UPU S10 standard · 20 postal operators

Postal & EMS tracking

Paste any 13-character UPU S10 number. We identify the destination postal operator from its country code and link you to their official tracking.

13 characters: 2 service letters + 9 digits + 2-letter country code (origin).

Try example: EE123456785US

How it works

  1. 1 Enter the 13-character S10 number from your shipping label or postal receipt.
  2. 2 We validate the check digit and read the 2-letter country code at the end.
  3. 3 You are redirected to the corresponding national postal operator (or shown their search page).

What is a UPU S10 number?

S10 is the international postal tracking standard administered by the Universal Postal Union. Every cross-border tracked, registered, EMS, or insured mail item carries an S10 number — 2 service letters, 9 digits (with a check digit), and the 2-letter ISO origin country code.
