The United States Postal Service (USPS) is the shipping company that utilizes "US" at the end of some of its tracking numbers.
Understanding USPS Tracking Number Formats
The United States Postal Service (USPS) employs various formats for its tracking numbers to provide customers with detailed information regarding their shipments. These formats are designed to be unique identifiers for each package as it moves through the postal system.
Specific Tracking Format Ending in "US"
One distinctive USPS tracking number format, commonly associated with international or specific service types, includes the "US" suffix. This particular format is identifiable by its structure:
- It is a 13-character alphanumeric sequence.
- It typically begins with two alphabetic characters.
- This is followed by nine numeric digits.
- The sequence concludes with the country code "US" for the United States.
Example:
An example of this format would be EA 999 999 999 US. This structure helps in identifying the origin country for international mail and provides a standardized format for tracking.
Here's a quick overview of this specific format:
| Company | Tracking Number Format | Description |

Other Common USPS Tracking Formats
While the "US" suffix is specific to certain types of mail, USPS also uses other common tracking number formats. The most prevalent one is a 20-digit numeric sequence. This format typically consists solely of numbers, providing a straightforward identifier for domestic packages. An example of this format would be 9999 9999 9999 9999 9999.
These varied formats ensure that USPS can manage and track a wide array of mail types, from standard domestic parcels to international shipments, each with its unique identifier structure.
