Frequently Asked Questions

Tracking your package is simple:

1. Go to our homepage
2. Enter your tracking number in the search box
3. Click "Track Package" or press Enter
4. View your tracking information

Our system automatically detects the courier from your tracking number, so you never select it yourself.

Tracking numbers vary by courier:

• USPS: 20-22 digits (e.g., 9400111899223456789012)
• FedEx: 12 digits (e.g., 123456789012)
• UPS: 18 characters starting with "1Z" (e.g., 1Z999AA10123456784)
• DHL Express: 10 digits (e.g., 1234567890)
• Amazon: TBA followed by 12 digits (e.g., TBA123456789012)
• China Post: 13 characters starting with letters (e.g., RB123456789CN)

We cover 1,000+ carriers through our tracking data providers, including:

• Major US Carriers: USPS, FedEx, UPS, Amazon Logistics, OnTrac (including former LaserShip numbers)
• International: DHL, FedEx, Aramex, SF Express, Deutsche Post
• Postal Services: China Post, Royal Mail, Canada Post, Australia Post, Japan Post
• Regional: Evri (formerly Hermes UK), Yodel, Purolator, and hundreds more

The tracker checks one number at a time. To follow several parcels:

• Your recent searches are automatically saved in your browser
• You can quickly access previously tracked packages from the homepage
• Open multiple browser tabs to track different packages simultaneously

There are several reasons why tracking might not work:

1. Package not in system yet: Wait 24-48 hours after shipment creation
2. Wrong tracking number: Double-check the number from your shipping confirmation
3. Wrong courier detected: Try the number on the carrier's own website
4. Courier system delay: The carrier's tracking system might be temporarily down
5. Invalid or expired number: Very old tracking numbers may no longer be in the system

If problems persist, contact the sender to verify the tracking information.

Tracking delays can happen for several reasons:

• Weekend/Holiday: Fewer scans happen on Sundays and public holidays, although USPS delivers on Saturdays and offers Sunday delivery for Priority Mail Express in many areas
• In transit: Long-distance shipments may not scan at every facility
• Customs: International packages can sit in customs for days or weeks
• Carrier delays: Storms, the late-November to December peak and network outages slow sorting, so gaps between scans grow

If tracking passes the worry threshold for its service in our guide to tracking that stops updating, contact the courier.

Follow these steps:

1. Check thoroughly: USPS notes the carrier may have left it in a safer spot, so check side doors, the mailbox, any parcel locker and with neighbors
2. Wait one business day: USPS asks you to wait one full postal business day after the delivered scan before submitting a service request
3. Check delivery photo: Some carriers provide photo proof of delivery
4. Contact the sender: They can file a claim or send a replacement
5. Contact the courier: File a missing package report with the carrier
6. Check your payment method: You may have buyer protection

Note: ParcelsZen cannot help with lost packages. Contact the sender or courier directly.

If auto-detection selects the wrong courier:

1. Check the number against our tracking number formats guide to see which carrier issued it
2. Track it on that carrier's own website, which is the authority

Some tracking number formats are similar across couriers, which can cause misidentification. A twelve-digit number can match more than one carrier.
