A USPS tracking number is a unique identifier for every package or mail item sent through the United States Postal Service. More than just a series of digits, it is a key tool for tracking a shipment's progress, verifying its delivery, and addressing any issues if the package is lost or delayed.
Tracking numbers vary in format depending on the mail class and service used, and they can be found on shipping receipts, confirmation emails, and package labels.

Conversely, alpha-numeric tracking number formats are also prevalent, particularly in parcels originating from abroad.
Less common USPS tracking number formats may comprise solely ten digits or a 13-character alpha-numeric sequence, beginning with two letters, followed by nine digits, and concluding with US. If your USPS tracking number starts with specific letters, such as EC or CP, it likely belongs to an international shipment category.
The initial four digits within a USPS tracking number disclose the type of mail service utilized by the package. These digits are commonly referred to as the service code.
For instance, tracking numbers commencing with 9400 signify the traditional USPS tracking code, while those starting with 9270 indicate Priority Mail Express shipments.
