Before you call
aicrazed will never ask you for a password, one-time passcode, gift card, or payment over the phone or in chat. Neither will USPS’s real support team. If someone claiming to represent USPS asks for these, hang up — you’ve reached a scammer, not support.
- We never ask for your password, one-time code, or payment details.
- The links above go to USPS’s own official domain — check your browser’s address bar.
- If a search result or ad shows a different number for USPS, treat it as unverified until you confirm it on their official site.
Common issues & how to resolve them
General guidance based on what usually works for this kind of issue — not USPS’s official policy.
Missing, late, or damaged mail
Use USPS's "Where Is My Package" tool first with your tracking number — it often surfaces more detail than the basic tracking status. Contact USPS above if a package shows no movement for several days.
Filing a claim
Domestic claims for insured mail can be filed online through USPS's claims system with proof of value and, for damage, photos. Keep your original mailing receipt — USPS typically asks for it.
Change of address and mail forwarding
Submit a change of address directly through USPS's official online form rather than a third-party site, since those sometimes charge an unnecessary fee. Contact USPS above if forwarding doesn't start as expected.
Package tracking
Tracking numbers can be entered directly on USPS.com for the most current scan history. Contact USPS above if a package is marked delivered but hasn't arrived.
PO Box services
PO Box rental, renewal, and payment can usually be managed online or at your local post office. Contact USPS above for availability or access issues at a specific location.
Click-N-Ship account issues
Password resets and label history are available directly in your Click-N-Ship account settings. Contact USPS above if a label was purchased but isn't showing in your account.
Average wait time
USPS doesn’t publish wait-time data — this isn’t a verified figure.
Best time to contact
General rule of thumb, not brand-specific data: contacting outside peak hours tends to mean a shorter wait.
