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?

Tracking may not update for 24 hours after mailing, during weekends/holidays, or when moving through facilities without intermediate scans. Rural routes have fewer scan points. If there are no updates for 3+ business days, contact USPS at 1-800-ASK-USPS (1-800-275-8777).

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?

First, check around your delivery location (porch, mailbox, with neighbors, or building office). Wait 24 hours as carriers sometimes mark items delivered early. If still not found, file a claim with USPS using their online form or by calling 1-800-ASK-USPS.
