About United States Postal Service (USPS)
The United States Postal Service (USPS) is an independent agency of the federal government and the only carrier bound by a universal service obligation, meaning it delivers to every residential and business address in the country, including remote rural routes and PO Boxes that private carriers often skip. Handling well over a hundred million delivery points six days a week, USPS is the backbone of American last-mile delivery. It also completes the final leg for many UPS, FedEx, and international shipments through workshare programs. USPS is best known for flat-rate Priority Mail boxes, First-Class letters, and its dense network of neighborhood post offices. On PackageTrackNow, an independent aggregator, you can follow USPS scans without visiting the official site. PackageTrackNow is not affiliated with the Postal Service.
USPS Services & Delivery Times
USPS offers a tiered lineup priced mostly by weight, zone, and speed:
- USPS Ground Advantage — economy ground service, typically 2–5 business days, with tracking and up to $100 insurance included.
- Priority Mail — 1–3 business days, popular for its flat-rate boxes and envelopes where zone doesn't affect price.
- Priority Mail Express — the fastest option, overnight to 2-day delivery with a money-back guarantee.
- First-Class Mail — letters, postcards, and lightweight envelopes.
- Media Mail — discounted rate for books, discs, and educational materials, usually 2–8 days.
Parcel Select and Marketing Mail cover bulk commercial shippers. Priority Mail Express even delivers on Sundays and major holidays in many areas for an added fee, and flat-rate packaging ships the same price to any domestic zone. Delivery windows are estimates, not guarantees, except on Express.
USPS Tracking Number Format
USPS uses the Intelligent Mail package barcode (IMpb), a 20–22 digit number that usually begins with 92, 93, or 94—for example 9400 1000 0000 0000 0000 00. You'll find it printed beneath the barcode on your shipping label, mailing receipt, or Click-N-Ship confirmation email. International items mailed through USPS instead use the 13-character S10 format: two letters, nine digits, and a country code such as US (for example LZ123456785US). If your tracking number starts with two letters rather than a 9, it is an international or registered-mail format. Enter the full string with no spaces on PackageTrackNow.
USPS Delivery Schedule
USPS delivers Monday through Saturday to virtually every US address, with no surcharge for residential or rural delivery. Priority Mail Express is delivered 365 days a year, including Sundays and holidays in most areas. USPS also handles Sunday and holiday delivery for many Amazon packages. There is no guaranteed delivery time window for standard mail classes, though Priority Mail Express carries a money-back delivery guarantee.
Tips for Tracking USPS
- Sign up for Informed Delivery to get emailed grayscale scans of mail and packages arriving that day.
- A number that shows no movement for a day or two is common—USPS scans at acceptance and delivery more reliably than at intermediate stops.
- Use USPS Hold Mail before travel so parcels aren't left on your porch.
- "Delivered" with nothing in hand? Wait 24 hours; carriers sometimes scan early. Then contact your local post office directly, as they have route-level detail the website doesn't.
- For Priority Mail Express delays, you may qualify for a refund of postage.

Frequently Asked Questions
Quick answers to common USPS tracking inquiries.
Your USPS tracking number appears in the shipping confirmation email from the retailer, on your receipt if you shipped in person, and in your order history on most e-commerce sites. It is usually labelled "tracking number", "tracking ID", or "consignment number".
USPS only records an update when the parcel is physically scanned. On long legs between facilities — or over weekends and holidays — a parcel can travel for a day or two without any new scan appearing. This is normal and does not mean the parcel is lost.
It means the parcel has left one USPS facility and is on a vehicle or aircraft heading to the next one. It is the most common status in any parcel's life and requires no action from you.
Check every entrance, your mailbox, and any parcel locker or safe place you have on file with USPS. Ask household members and immediate neighbors. If it has not appeared after 24 hours, contact USPS to open an investigation and let the sender know.
