USPS Tracking FAQ
How long does USPS tracking take to update?
USPS tracking typically updates within 24 hours of a scan. Initial scans may take up to 48 hours to appear in the system after the package is accepted.
What does "In Transit to Next Facility" mean?
This status means your package is moving between USPS facilities and is on its way to the next processing center or delivery post office.
Why is my USPS tracking not updating?
Tracking may not update due to the package being in transit between facilities, weekends/holidays, or occasionally system delays. If no update for 7+ days, contact USPS.
Can I track USPS packages without a tracking number?
No, you need a valid tracking number to track USPS packages. Check your receipt or shipping confirmation email for the tracking number.
What should I do if my package is lost?
If your tracking shows no updates for more than 7 days, file a missing mail search request at usps.com or call 1-800-275-8777. For insured packages, you can file a claim.
