USPS tracking
Track your USPS package in real time — status, estimated delivery, and the full timeline, no sign-up required.
How to find your USPS tracking number
USPS tracking numbers are usually 20–22 digits (e.g. 9400 1000 0000 0000 0000 00) or a 13-character format like EA 000 000 000 US for international mail.
Find the number on your shipping receipt, confirmation email, or the label.
USPS covers First-Class, Priority Mail, Priority Mail Express, and Ground Advantage.
Status can take a few hours to appear after the label is created.
