The Letter Pilot

USPS Tracking Number Lookup

Enter a Certified Mail or USPS package tracking number to check its latest status and recent scans.

Enter 20-30 digits, or an international number such as EA123456789US. Spaces, hyphens, and lowercase letters are OK.

For overseas mail, our USPS international tracking guide explains tracking coverage and helps you find the destination country's postal service.

Certified Mail Tracking Number Lookup

Use the lookup above when you already have a USPS Certified Mail tracking number and want to check its current delivery status. Certified Mail numbers are typically 20-30 digits and commonly begin with 9407, 9208, or 9307.

Paste the number with or without spaces or hyphens. When USPS data is available, the tracker shows the latest status, scan time, location, and recent delivery events. If USPS keeps the detailed record on its own site, you can continue with the USPS.com button.

Frequently Asked Questions

What USPS services can I track with this tool?

You can use this tool to look up Priority Mail, Certified Mail, and eligible international mail when you have a USPS tracking number.

Where do I find my USPS tracking number?

Check your email first. If you used The Letter Pilot, we sent the tracking number by email and saved it in your dashboard. If you mailed the item at a Post Office, the clerk should have given you a receipt with the tracking number on it.

Why isn't my tracking updating?

USPS updates tracking as scans become available. Check the latest status and the delivery standard for your mail service; a gap between scans alone does not establish that an item is lost. Follow the next steps on USPS.com when your item is eligible for additional research.

Can I track multiple packages at once?

This tool tracks one package at a time. For multiple packages, you can use USPS.com which allows tracking up to 35 numbers at once, or track each one individually with this tool.

What if my package shows "Delivered" but I didn't receive it?

Check your mailbox, parcel locker, porch, other sheltered locations, household members, and building office. If it is still missing more than one postal business day after the delivered scan, USPS says to submit a service request to your local Post Office for eligible items. A service request is not an insurance claim: claims have separate coverage requirements and filing periods.
