About USPS Package Tracking Service

The United States Postal Service (USPS) is the independent agency of the federal government responsible for providing postal service in the United States. Founded in 1775, USPS is the oldest federal institution in the country and operates the world's largest civilian fleet of vehicles, delivering mail and packages to every address in the United States, including 160 million residences, businesses, and Post Office Box addresses.

Our free USPS tracking service allows you to monitor your shipments in real-time, from the moment they're accepted at a USPS facility until they reach their final destination. Whether you're tracking a Priority Mail package across the country or an international First Class package, our tracking tool provides detailed status updates and estimated delivery dates for all USPS services with tracking.

Track your USPS packages easily by entering your tracking number in the search box above.

Complete Guide to USPS Tracking

Understanding USPS Tracking Numbers

USPS tracking numbers follow specific formats depending on the service type and shipping method. Understanding your tracking number format helps you identify the service type and expected delivery speed.

Priority Mail and Priority Mail Express: These services use 22-digit numeric tracking numbers starting with "9400" or "9407" for Priority Mail and "9270" for Priority Mail Express. For example: 9400100000000001234567 or 9270100000000001234567. These tracking numbers include comprehensive end-to-end tracking throughout the USPS network.

First-Class Package Service: First-Class Package tracking numbers are 22 digits long and start with "9205", "9214", or "9261". Example: 9205500000000001234567. These provide the same level of tracking as Priority Mail but are used for packages under 13 oz.

International Services: USPS international tracking numbers use different formats depending on the destination and service level:

• Priority Mail International: 13-character alphanumeric numbers starting with "CP", "RA", or "RB" followed by 9 digits and ending with "US" (e.g., CP123456789US, RA987654321US)
• Global Express Guaranteed: 13-character alphanumeric numbers starting with "82" followed by 9 digits and ending with "US" (e.g., 82123456789US)
• First-Class Package International: 13-character alphanumeric numbers starting with "LK", "RX", "CP", or "RR" followed by 9 digits and ending with "US" (e.g., LK123456789US)

Certified Mail and Special Services: Certified Mail tracking numbers are 20 digits long and start with "9407" or "9414". These provide proof of mailing and delivery but may not include the same detailed scan history as package services. Registered Mail tracking numbers start with "9208" and provide maximum security with chain-of-custody tracking.

How USPS Tracking Works

USPS's tracking system uses barcode scanning technology at every stage of the shipping journey. When a package is created and accepted, the tracking number's barcode is scanned, creating the first "Shipping Label Created" or "Electronic Shipping Info Received" scan in the system. This initial scan confirms USPS has custody of the package.

As the package moves through USPS's network, it's scanned at each processing facility, during sorting, when loaded onto transport vehicles, upon arrival at destination facilities, and finally during delivery. Each scan generates a tracking update with a timestamp and location, allowing customers to monitor the package's progress in real-time.

USPS operates major processing plants in strategic locations across the United States including Chicago, Dallas, Los Angeles, and New York. Packages are typically scanned when entering and exiting these facilities. For long-distance shipments, there may be 3-5 scans during transit before the package reaches the local delivery center.

The tracking system integrates with USPS's delivery network to provide estimated delivery dates based on service type, origin, destination, and current package location. While premium services like Priority Mail Express offer guaranteed delivery timeframes, other services provide estimated delivery windows that may vary based on weather, volume, and other factors.

USPS Delivery Guarantees and Timelines

Priority Mail Express Delivery: USPS guarantees overnight to 2-day delivery for most US addresses with delivery by 6:00 PM or 8:00 PM depending on the destination. This service includes a money-back guarantee if the package isn't delivered by the guaranteed date. Major metropolitan areas typically receive same-day delivery, while rural addresses may have 2-day delivery.

Priority Mail Delivery: Priority Mail provides estimated delivery dates based on origin and destination zip codes. Delivery typically occurs within 1-3 business days for most domestic addresses. While not guaranteed like Priority Mail Express, Priority Mail has a high on-time delivery rate and includes $50 insurance automatically.

First-Class Mail Delivery: First-Class Mail delivery times vary by distance:

• Local (same city/county): 1-2 business days
• Regional (same state/surrounding states): 2-3 business days
• National (opposite coast): 3-5 business days

International Services: USPS Priority Mail International delivers to most major destinations in 6-14 business days with typical delivery times of 6-10 days to Canada, 6-12 days to Europe, and 6-14 days to Asia and South America. Global Express Guaranteed provides 1-3 business day delivery to most countries with date-certain delivery and money-back guarantee.

Factors Affecting Delivery Times: Weather events, particularly winter storms or hurricanes, can delay deliveries. USPS doesn't operate regular delivery services on Sundays or major holidays like Christmas Day, New Year's Day, Thanksgiving Day, and July 4th. Address accuracy is critical - incomplete addresses cause significant delays. During USPS peak season (November-January), delivery times may be extended due to increased volume.

Common USPS Tracking Statuses Explained

"Pre-Shipment Info Sent to USPS": This is the first status you'll see when a shipping label is created. It means the sender has created the label and USPS has received the electronic shipping information, but the physical package hasn't been scanned yet. This is normal for the first 24 hours. If this status persists for 3+ days, the package may not have been dropped off yet.

"Accepted at USPS Origin Facility": USPS has physically received and scanned your package at a USPS facility. This is the first confirmed scan showing USPS has custody. The package will now enter the sorting and transportation network. This scan typically occurs within 24 hours of drop-off or pickup.

"Departed USPS Regional Facility": Your package has left the regional processing center and is in transit to the destination regional facility or local post office. This status indicates the package is moving through the USPS network and is typically seen 1-2 days after acceptance for domestic shipments.

"Arrived at USPS Regional Destination Facility": Your package has arrived at the USPS facility serving the destination address. This is a key milestone indicating the package is in the local area and will be delivered soon. For Priority Mail Express and Priority Mail, this scan typically appears on the day before delivery.

"Out for Delivery": Your package is loaded on a USPS delivery vehicle and scheduled for delivery today during normal delivery hours (typically 8 AM - 5 PM local time). Most items showing this status are delivered the same day. USPS carriers deliver to the same addresses on the same days each week, so delivery time estimates become more accurate as the day progresses.

"Delivered": Your package was successfully delivered. The tracking shows the delivery time, date, and location (e.g., "Delivered to Front Door," "Delivered to Mail Room," "Delivered to Package Locker"). For signature-required items, the tracking will show who signed for the package.

"Notice Left (No Authorized Recipient Available)": The USPS carrier attempted delivery but couldn't complete it because no authorized recipient was available to accept the package. A PS Form 3849 notice is left with instructions for pickup at the local post office. Items are typically held for 15 days before being returned to sender.

"Available for Pickup": Your package is ready to collect at the post office shown in the tracking details. Bring valid government-issued photo ID and the notice card if you received one. For USPS Package Pickup locations, you may need to show the confirmation email or text message. Packages are held for 15 calendar days before being returned to sender.

"Forwarded": Your package has been redirected to a new address based on a USPS Change of Address form filed by the recipient. This scan appears when the package reaches the destination post office and is rerouted. Delivery time may be extended by 1-3 additional business days.

"Return to Sender": The package is being returned to the original sender. Reasons include multiple failed delivery attempts, incorrect or incomplete address with no way to correct it, refused by recipient, or undeliverable as addressed. The tracking will show return journey details.

What to Do If USPS Tracking Isn't Updating

First 24-48 Hours - Normal Delays: If you just received a tracking number and it shows "Pre-Shipment Info Sent to USPS" or no information at all, wait 24-48 hours. Tracking numbers activate when packages are physically scanned, not when labels are printed. The sender may have printed the label but not dropped off the package yet. This is the most common reason for "no tracking updates."

Stuck in Transit - Check Timeline: Review the expected delivery timeline for your service level. Priority Mail can take up to 3 days, and rural deliveries naturally have fewer scans. If tracking hasn't updated in 2-3 days for Express services or 4-5 days for Priority Mail, there may be an issue. Long-distance shipments may legitimately have longer gaps between scans.

Verify Tracking Number Accuracy: Confirm you have the complete, correct tracking number with no missing digits or typos. USPS tracking numbers are case-insensitive but must be exactly as provided. Try tracking on both usps.com and third-party tracking sites. If the tracking number format doesn't match USPS's standard formats, verify with the sender.

Weekend and Holiday Considerations: USPS doesn't operate regular delivery services on Sundays or major holidays. If your last scan was on Friday, the next update will likely be Monday. Processing facilities have reduced operations on weekends, which can cause tracking update gaps. During major holidays, there may be no tracking updates for 2-3 days.

Weather and Service Disruptions: Severe weather events, particularly winter storms in northern states or hurricanes in coastal areas, can delay shipments and scanning operations. USPS posts service alerts on their website when weather significantly impacts operations. During USPS labor disputes or peak season volume, tracking may not update regularly and delivery timelines are unpredictable.

Contact USPS Customer Service: If tracking hasn't updated beyond expected timeframes or shows unusual patterns, call USPS customer service at 1-800-ASK-USPS (1-800-275-8777). Have your tracking number ready. They can file a service ticket to investigate the package's location and status. USPS also provides online chat support through their website and mobile app.

File a Service Ticket Online: Visit usps.com and navigate to "Track & Manage" > "Help with Missing or Delayed Mail." Provide the tracking number, shipping and destination addresses, and description of the issue. USPS typically responds within 2-5 business days with an investigation update. This creates an official record of the delay.

Contact the Sender: If you're the recipient and tracking shows no movement, contact the sender to confirm they actually shipped the package and provided the correct tracking number. The sender has more options and authority to file claims or investigate with USPS since they purchased the shipping service.

When to File a Lost Package Claim: USPS packages can be considered lost if tracking shows no updates for 7 days for Priority Mail Express, 14 days for Priority Mail and First-Class Package Service, or 30 days for other services. Don't file lost package claims prematurely - USPS won't process them until these waiting periods expire. Most "stuck" packages eventually show up, especially during USPS peak season when volume is high.

Filing Claims for Lost or Damaged Items

Eligibility and Coverage: USPS packages include automatic insurance coverage at no additional cost: $100 for Priority Mail Express, $50 for Priority Mail, and up to $5,000 for Registered Mail. Additional insurance can be purchased up to $5,000 for most services. Items improperly packaged, prohibited items, and perishables may not be eligible for claims.

When to File a Claim: For lost items, you must wait the minimum time periods mentioned above before filing. For damaged items, file within 60 days of the mailing date. Claims must be filed within 120 days of the mailing date for most services. Don't wait too long - time limits are strictly enforced. For international shipments, additional documentation may be required.

Who Can File: Only the sender (person who paid for shipping) can file claims with USPS. Recipients cannot file claims directly. If you're the recipient of a lost or damaged package, contact the sender and request they file a claim on your behalf. The sender is the USPS customer and has the contractual relationship.

Required Documentation: To file a successful claim, you'll need: (1) the complete tracking number, (2) original receipt or proof of purchase showing item value, (3) detailed description of contents including brand, model, serial numbers, (4) for damaged items: photos of damage to packaging and contents, and (5) original packaging if damaged - don't throw it away.

How to File Online: Visit usps.com, log in to your USPS account, navigate to "Track & Manage" > "File a Claim." Complete the online claim form with all required information and upload supporting documentation (receipts, photos, invoices). The online system guides you through each required field and document type.

Claim Valuation: USPS reimburses the lesser of: (1) the item's actual purchase price, (2) current market value, or (3) the coverage limit ($100 standard or higher if additional coverage was purchased). Sentimental value, potential earnings, and consequential damages are not covered. For damaged items, repair costs may be covered instead of full replacement if lower.

Processing Timeline: USPS typically investigates and resolves claims within 5-7 business days. Complex cases or high-value claims may take longer. You'll receive email updates as the claim progresses through investigation, review, approval/denial stages. If additional information is needed, USPS will contact you - respond promptly to avoid claim rejection.

Claim Denial and Appeals: Common reasons for claim denial include: insufficient wait period, inadequate packaging, incomplete documentation, prohibited items, missing proofs of value, or filing after the deadline. If your claim is denied and you disagree, you can appeal with additional supporting documentation within 30 days of the denial decision.

Packaging Requirements for Claims: USPS requires specific packaging standards for items to be eligible for damage claims. Fragile items must be bubble-wrapped and placed in rigid boxes with at least 2 inches of cushioning material on all sides. Liquids must be in sealed plastic bags. Electronics need anti-static protection. Inadequate packaging is the #1 reason for damage claim denials.

Tips for Successful USPS Tracking

Choose the Right Service Level: Select shipping services based on urgency and value. Use Priority Mail Express for time-sensitive items that need guaranteed delivery. Use Priority Mail for non-urgent packages where cost is more important than speed but tracking is still needed. Use First-Class Mail for lightweight letters and documents under 13 oz where cost is the primary concern.

Ensure Address Accuracy: Double-check recipient addresses including apartment numbers, suite numbers, and zip codes. Use USPS's Address Validation Tool to verify addresses before shipping. Include phone numbers and email addresses so USPS can contact recipients about delivery issues. Incorrect addresses are the leading cause of delivery failures and returns.

Package Properly for Protection: Use sturdy corrugated boxes appropriate for item weight and size. Cushion items with bubble wrap, foam peanuts, or crumpled paper - minimum 2 inches on all sides for fragile items. Seal boxes with quality packing tape (not masking tape). Mark fragile items clearly. Proper packaging prevents damage and ensures claim eligibility.

Save Your Receipt and Tracking Number: Always keep your USPS mailing receipt with the tracking number. Take a photo or write down the tracking number immediately. If the receipt is your only proof of mailing and you lose it, filing claims becomes difficult. For valuable items, consider emailing yourself the tracking number as backup.

Enable Delivery Notifications: Sign up for USPS Informed Delivery to receive automatic email notifications when packages are shipped, out for delivery, delivered, or delayed. This is free and much more convenient than manually checking tracking. Informed Delivery also provides grayscale images of incoming mail pieces for residential addresses.

Use USPS Collection Points When Appropriate: If you're frequently not home during delivery hours or live in an area with package theft concerns, use USPS Collection Points (Post Office Boxes, Package Pickup locations) for secure pickup. Having packages sent directly to Collection Points eliminates failed delivery attempts and ensures secure storage until pickup. It's free for most USPS services and more secure than doorstep delivery for valuable items.

Insure Valuable Items: For items worth more than the automatic insurance coverage, purchase additional insurance. Priority Mail Express includes $100, Priority Mail includes $50, but additional coverage costs only a few dollars extra and protects your valuable shipments. Always keep receipts and documentation proving item value - required for filing claims. Don't skip insurance thinking "it won't happen to me."

Ship Early for Deadlines: Don't wait until the last minute for birthday gifts, holiday packages, or deadline-sensitive documents. Even Priority Mail Express can be delayed by weather or operational issues. Ship at least 2-3 business days before critical deadlines. During holiday seasons, add even more buffer time - December is USPS's busiest month.

Track Proactively: Check tracking regularly, especially around estimated delivery dates. If you notice unusual delays or tracking hasn't updated in expected timeframes, contact USPS immediately rather than waiting. Early intervention often resolves issues before they become serious problems. Don't assume "no news is good news."

Understand International Requirements: For international shipments to USPS, research destination country customs requirements, prohibited items, and typical processing times before shipping. Accurately complete customs forms - errors cause delays and can result in package seizure. Inform recipients they may owe duties and taxes. Set realistic expectations for international delivery timelines.

Keep Communication Open: If you're the sender, provide tracking numbers to recipients immediately after shipping. If you're the recipient expecting a package, stay in contact with the sender about tracking updates and any issues. Good communication between sender and recipient resolves most tracking problems quickly.

People Also Ask About USPS Tracking

What does a USPS tracking number look like?

USPS tracking numbers are typically 20 or 22 digits long and start with specific prefixes depending on the service type:

• Priority Mail: 9400 1000 0000 0000 0000 00 (22 digits)
• Priority Mail Express: 9270 1000 0000 0000 0000 00 (22 digits)

• International: CP 123456789 US or EA 987654321 US (13 characters)

Why is my USPS tracking number not found?

If your USPS tracking number isn't found, it's usually because:

1. The shipping label was printed but not scanned yet (wait 24-48 hours)
2. You entered the tracking number incorrectly (check for typos)
3. The service doesn't include tracking (First-Class Mail letters don't have tracking)
4. The package hasn't been dropped off at USPS yet

How accurate is USPS tracking?

USPS tracking is generally accurate for packages (Priority Mail, Priority Mail Express, First-Class Package Service) with 95%+ scan rate at major facilities. However, tracking may be less frequent for rural deliveries or during peak holiday season. Expect scans every 4-8 hours during transit for domestic shipments.

Can I see exactly where my USPS package is right now?

USPS tracking shows the last scanned location, not real-time GPS tracking like some private carriers. Your package location updates when scanned at processing facilities, during transit, and at delivery. The most recent scan in your tracking history shows the current known location.

What does "Pre-Shipment Info Sent to USPS" mean?

This status means the sender created a shipping label and USPS received the electronic shipping information, but the physical package hasn't been scanned at a USPS facility yet. This is normal for the first 24-48 hours after a label is printed. The status will update to "Accepted" once USPS scans the package at a Post Office or during pickup.

How long does USPS tracking take to update?

USPS tracking typically updates within 24-48 hours of package acceptance. After the first scan, updates occur at key points: departure from origin facility (4-8 hours), arrival at destination facility (next day), out for delivery (morning of delivery day), and delivered (within minutes of drop-off). Express services update more frequently than standard services.
