Frequently Asked Questions
USPS tracking says delivered but no package — what should I do?
Check around your mailbox, porch, and with neighbors. Wait 24 hours — packages are sometimes scanned delivered 1 day early. If still missing contact your local post office and submit a missing mail search at usps.com/help/missing-mail.htm. File an insurance claim if insured.
How long does USPS take to deliver?
Priority Mail Express: 1–2 calendar days (guaranteed). Priority Mail: 1–3 business days. First Class Package: 1–5 business days. USPS Ground Advantage: 2–5 business days. Media Mail: 2–8 business days. Times may extend during peak holiday seasons.
USPS package stuck in transit — what does it mean?
In transit arriving late means your package is moving but delayed. Common during holiday season Nov–Jan and after weather events. Submit a missing mail search at usps.com after 7 days with no update. Call 1-800-275-8777 to open a service request.
