Frequently Asked Questions
What USPS services can I track with this tool?
You can track any USPS service with a tracking number, including Priority Mail, Priority Mail Express, Certified Mail, First-Class Package Service, Parcel Select, Media Mail, Registered Mail, and more. The tracking number is typically 20-22 digits for domestic mail or 13 characters for international mail.
Where do I find my USPS tracking number?
Your tracking number is on your mailing receipt (PS Form 3817 for Certified Mail, or your Priority Mail receipt). For online services, it's in your email confirmation. Tracking numbers usually start with specific prefixes: 9407 (Certified Mail), 9205/9208 (Priority Mail), 9270 (Priority Mail Express), or EA/CP/LK followed by numbers for international mail.
How long does it take for tracking to show up?
Tracking information typically appears within 24 hours after the item is mailed. The first scan usually happens at the origin post office when your item is accepted. If tracking doesn't show after 24 hours, check that you entered the number correctly or contact USPS.
What does each tracking status mean?
Common statuses include: "Accepted" (USPS received your item), "In Transit" (moving through mail network), "Out for Delivery" (on carrier's truck today), "Delivered" (successfully delivered), and "Notice Left" (delivery attempted but signature required and no one available). For detailed status explanations, check our tracking status guide.
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.
Is USPS tracking free?
Yes! USPS provides free tracking for all trackable mail classes. Services like Priority Mail, Priority Mail Express, and Certified Mail include tracking at no additional cost. You can check your tracking as many times as you want.
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.
