In-depth guides to UPS, FedEx, USPS, DHL, Royal Mail, Canada Post, Amazon Logistics, and Chinese carriers. Everything you need to understand how each carrier works — and when to use which one.
UPS, FedEx, USPS, DHL, Amazon Logistics, Royal Mail, Canada Post, and Chinese carriers — eight different companies, eight different tracking systems, and eight different ways a package can be delayed. 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 has the most detailed tracking data in the industry — every scan tells you exactly where the package sits in their network. USPS delivers 421 million pieces a day through a network built around first-class mail, not parcel tracking, which is why ground packages go quiet for 48 hours and then arrive without warning. 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 is written to answer the specific question you arrived with, not to explain how shipping works in general.

Read articleUSPS First Class Mail is the cheapest for packages under 1 lb, typically $4–$7 depending on weight and distance. For 1–5 lb packages, compare USPS Priority Mail against UPS Ground and FedEx Ground — USPS wins on shorter distances, the others win on cross-country routes. The UPS vs FedEx vs USPS comparison covers the pricing breakdown with specific examples.
DHL Express delivers on Saturdays in most US cities at no extra charge. 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, which can be 12–24 hours later on domestic routes. 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. You can only track TBA shipments through Amazon's website or app. Amazon Logistics does not share real-time data with third-party tracking sites. 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 request a package intercept through USPS.com before the hold expires to extend pickup time or redirect the shipment.
