What is USPS Tracking?

USPS Tracking is a package monitoring service by the United States Postal Service that shows a shipment’s progress from pickup to final delivery. It uses barcode scans at key locations—post offices, distribution centers, and delivery points—to update tracking details. Tracking is included with most USPS services and helps you see delivery status, estimated arrival times, and any delays along the way.

USPS Tracking Number

To access your shipment data, you need the unique label identification number assigned to your mailpiece. Our USPS tracking tool uses these specific codes to locate your item within the federal mail stream:

Tracking Number: The standard 22-digit numeric code found on your receipt or shipping label.
Article Number: Used for extra services like Certified Mail or Registered Mail.
Customs ID: An alphanumeric code assigned to international packages for customs clearance tracking.

USPS Tracking Number Formats

Identifying the correct format is essential, as the USPS uses different numbering schemes for different classes of mail. Here is a breakdown of the most common formats:

USPS Tracking (Standard): A 22-digit numeric string, typically starting with 9 (e.g., 9400 1000 0000 0000 0000 00).
Priority Mail Express: Consists of 2 letters, 9 digits, and 2 letters (e.g., EC 000 000 000 US).
Priority Mail International: Generally starts with CP or CJ, followed by 9 digits, ending in US (e.g., CP123456789US).
Registered Mail: Starts with RA, followed by 9 digits, ending in US (e.g., RA123456789US).

About the United States Postal Service (USPS)

The United States Postal Service (USPS), also known simply as the “Post Office,” is an independent agency of the executive branch of the United States federal government. Its roots trace back to 1775, with Benjamin Franklin appointed as the first Postmaster General.

The USPS is one of the few government agencies explicitly authorized by the U.S. Constitution and operates under a universal service obligation to provide mail service to all Americans, regardless of geography, at uniform prices and quality. With a workforce of over 600,000 employees and a fleet of more than 230,000 vehicles, the USPS maintains the largest civilian vehicle fleet in the world.

It delivers to more than 160 million addresses across the country, handling everything from personal letters and ballots to e-commerce parcels and pharmaceuticals. Unlike private carriers, the USPS receives no direct tax dollars for operating expenses and relies on the sale of postage, products, and services to fund its operations.

USPS Informed Delivery Feature

USPS offers a unique digital feature called Informed Delivery, which complements physical tracking. This service sends a daily email to users with grayscale images of the letter-sized mail arriving that day, along with tracking information for incoming packages. It allows users to manage deliveries and leave instructions for carriers before the mail even arrives.

Delivery Times and Schedules

Delivery times shown in USPS tracking results depend on the service class and distance. The network operates six days a week for mail, with expanded parcel delivery:

Ground Advantage: Typically delivers within 2 to 5 business days.
Priority Mail: Delivers within 1, 2, or 3 business days based on origin and destination.
Sunday Delivery: Generally restricted to Priority Mail Express and high-volume Amazon parcels in select areas.

USPS Insurance and Extra Services

Many tracked shipments include insurance or special handling. You can verify if these services are active on your package:

Certified Mail: Provides proof of mailing and delivery record. Often used for legal or important documents; requires a signature upon delivery.
Registered Mail: The most secure mail service offered. Items are kept under lock and key and signed for at every handoff point in the network.
Included Insurance: Ground Advantage and Priority Mail include up to $100 of insurance coverage automatically.

If you are not home to receive a package that requires a signature or is too large for the mailbox, the carrier will leave a PS Form 3849 (Peach Slip).

Redelivery: You can use the number on the slip to schedule a redelivery for a specific date via the USPS website.
Pickup: Alternatively, the package is held at your local Post Office for a limited time (usually 15 days) for you to pick up in person.
