Guides to UPS, FedEx, USPS, DHL, Royal Mail, Canada Post, Amazon Logistics and the main Chinese carriers. Each one covers a single carrier's tracking statuses, delivery network and the problems you are most likely to meet with it.
UPS, FedEx, USPS, DHL, Amazon Logistics, Royal Mail and the Chinese carriers (China Post with its ePacket service, and Yanwen) each run their own tracking system, with their own status wording and their own scan points. This category covers each one specifically because treating all carriers as interchangeable is the reason most shipping confusion happens in the first place.
The guides here cover what each carrier's tracking statuses actually mean, how their delivery networks are structured, and which situations each handles well or poorly. UPS tracking lists the city of the facility at each scan. USPS processed and delivered an average of 361.1 million mailpieces a day in 2025, of which 22.7 million were packages (USPS Postal Facts), so parcels move through a network built for letters. That is one reason a ground package can show no new scan between facilities and then arrive. DHL Express is a different product entirely: built for international speed, priced accordingly, and worth understanding before you commit to it.
Start with the UPS vs FedEx vs USPS comparison if you are new here. Read the Amazon TBA guide if a tracking number starting with TBA has ever confused you. Each article answers one practical question, such as what a status means, how long a gap is normal or when to file a claim.

USPS Ground Advantage is the service for a parcel under 1 lb, priced in four weight tiers below a pound and by zone. As of October 2026, prices start at $8.40 at a Post Office, and Click-N-Ship labels get lower Commercial Rates. First-Class Mail is letters, postcards and flat envelopes only since July 2023, so it cannot carry a box whatever it weighs. For packages of 1 to 5 lb, compare USPS Priority Mail with UPS Ground and FedEx Ground in each carrier's own price calculator for your route, because the cheapest option changes with distance and weight. The UPS vs FedEx vs USPS comparison covers the pricing breakdown with specific examples.
DHL Express sells Saturday Delivery as an optional service at $46.00 per shipment (as of October 2026), and its 2026 US rate guide states that this service is not available in the U.S. or U.S. territories. DHL eCommerce, the slower, cheaper option: delivers Monday through Saturday. Sunday delivery is not standard for either service. If Saturday delivery is critical, confirm the specific service type on your shipment before assuming it will arrive.
"In Transit to Next Facility" means your package is physically moving between two UPS hubs, on a truck or aircraft. You will not see another scan until it arrives at the next facility, and the gap depends on how far apart the two facilities are. This status during overnight hours is normal and does not indicate a problem.
TBA numbers belong to Amazon Logistics: Amazon's own delivery network, not to UPS or FedEx. Amazon shows TBA tracking in Your Orders and on its Track a Package page (track.amazon.com), where you enter the tracking ID. Other trackers, ParcelsZen included, can only show the events Amazon passes to their data provider, so check Amazon's page first if another tracker shows nothing. The Amazon TBA guide explains exactly how these numbers work and how to get the most accurate delivery information.
USPS holds packages at the post office for 15 days after the first failed delivery attempt. After 15 days the package returns to sender. Priority Mail Express has a shorter hold, typically 5 days. You can schedule a Redelivery at usps.com or collect the parcel at the Post Office before the hold expires. Package Intercept is a different service: the sender files it, and it stops a parcel before delivery rather than extending a hold.
