How to Contact USPS Online
USPS does not maintain a public general-support email address.Digital requests are handled through official web forms.
- Primary Portal: Access all official forms, tools, and updates on the main USPS Contact Us page.
- Online Help Request Form: Filling out an online inquiry generates a case number and is routed to the appropriate USPS support team. Follow-up notes and case updates are sent to your email.
Choose the Right Contact Method by Problem
A tracked package shows “Delivered” but is missing
Carriers log a “Delivered” scan when the item is dropped off.
Check the mailbox, parcel locker, porch, side or back entrance, garage, household members, neighbors, building management, and reception desk.
USPS advises waiting more than one full postal business day after the delivered scan — carriers occasionally scan an item slightly ahead of physically dropping it off.
If the item is still missing after that, don’t call the main hotline first: phone agents see the same tracking status you do.
Submit an online Help Request Form instead, which flags the item for review at the local delivery unit.

Regular mail is late and has no tracking number
Phone representatives can’t track standard First-Class mail without a tracking number.
Ask the sender to confirm the mailing date and address, and compare the timeline against the USPS service standard.
For a missing item or a recurring delivery problem at a specific address, use the USPS locator to find your local Post Office’s direct number, or submit the online form.
A USPS website, account, PO Box, or Click-N-Ship feature isn’t working
Call Technical Support at 1-800-344-7779, or open a technical ticket online.
Keep screenshots, the page address, the time of the error, browser/device details, and the exact error message ready.
Looking for a virtual PO Box instead of dealing with USPS PO Box logistics? That’s a different route entirely.
You need stamps, a Postal Store order, or free supplies
Postal Store orders and free shipping supplies use different numbers and schedules — see the table above. Use the issue-specific contact rather than General Customer Care.
You need a local service or facility
Use the USPS location finder for a Post Office, collection box, self-service kiosk, passport service, PO Box service, pickup, and published hours. Call the listed retail location only when the issue belongs to that specific facility.

When to Contact a Local Post Office
- Repeated missed or irregular mail delivery at the same address
- A local hold-mail, redelivery, pickup, or PO Box issue
- A delivery notice naming that specific Post Office
- A package status that instructs you to contact the local delivery unit
Use the official locator to confirm the address, hours, and phone number.
A regional processing facility shown in tracking is not normally a customer pickup location — these are automated sorting hubs without public service counters.
Complaints, Theft, and Fraud
Start an ordinary service complaint through USPS customer service or your local Post Office, and keep the service-request number.
For suspected mail theft, mail fraud, or a crime involving the mail, use the reporting path provided by the U.S. Postal Inspection Service — don’t send a routine late-package complaint to a law-enforcement channel.
For workplace misconduct, waste, or internal fraud involving USPS operations or employees, the USPS Office of Inspector General has a separate reporting role.
Use the description on the official site to choose the correct agency.
