The main USPS customer service number and what it handles
The general United States Postal Service customer service line is 1-800-275-8777. This number connects you to representatives who handle questions about mail delivery, package tracking, post office locations, and account issues. The line operates Monday through Friday, 9 a.m. to 7 p.m. Eastern time, and Saturday 9 a.m. to 5 p.m. Eastern time. It is closed on Sundays and federal holidays.
When you call, you will hear an automated menu. Press 1 for English or 2 for Spanish. From there, the system will route you based on your question — tracking a package, finding a post office, reporting mail theft, or speaking to a representative about billing or account problems. If you know what you need before calling, having that information ready (tracking number, ZIP code, or account details) will speed up the process.
Wait times vary by time of day and season. Early morning calls and mid-week calls typically have shorter waits than late afternoon or Monday mornings. If you reach an automated system that cannot solve your problem, you can usually press a button to hold for the next available representative rather than hanging up and calling back.
Key Takeaways
- The main USPS customer service number is 1-800-275-8777, available Monday through Saturday during business hours.
- The automated menu routes you by topic, so having your tracking number or ZIP code ready will get you to the right department faster.
- For package tracking, you can also use the USPS website or the Informed Delivery email service instead of calling.
- If you need to report mail theft or a missing package, the phone line can file a report and provide next steps.
- Post office locations have their own direct numbers, which you can find on the USPS website by entering your ZIP code.
Tracking a package without calling
If you only need to track a package, calling is usually not necessary. The USPS website at usps.com has a tracking tool where you enter your tracking number and see real-time updates on delivery status. This is faster than waiting on hold and works 24 hours a day.
You can also sign up for Informed Delivery, a free USPS email service that shows you images of mail and packages arriving at your address each day. This service alerts you when a package is out for delivery and when it has been delivered. Many people find this more useful than calling for individual tracking updates.
If your package shows as delivered but you have not received it, the website will guide you through filing a claim. You can start this process online before calling, which gives you documentation to reference if you do need to speak to a representative.
Reaching a specific post office directly
If you need to speak to someone at a particular post office — to ask about hours, hold mail, or pick up a package — calling that location directly is faster than the main customer service line. Go to usps.com, click "Find Locations," enter your ZIP code or address, and the results will show phone numbers for nearby post offices.
Post office hours vary by location. Many branches close for lunch and have shorter Saturday hours. Calling ahead before you visit saves a wasted trip, especially if you need a specific service like passport photos or certified mail.
Reporting mail theft or missing mail
If mail or a package has gone missing, call 1-800-275-8777 and select the option for reporting mail theft or loss. The representative will ask for details: what was expected, when it should have arrived, and whether you have a tracking number. They will file a report and explain what happens next.
For packages, USPS will investigate if the package shows as delivered but you did not receive it. For regular mail, the process is slower, but reporting it creates a record. If the missing item contained checks, money, or important documents, also contact your bank or the sender to report the loss.
If you suspect mail is being stolen from your mailbox regularly, the post office can advise you on options like a locked mailbox or holding mail at the post office until you can pick it up.
Business and commercial accounts
If you have a business account or use USPS for shipping at volume, there is a separate line for commercial customers: 1-800-222-1811. This number connects you to representatives who handle account billing, shipping discounts, and bulk mail services. Hours are Monday through Friday, 8 a.m. to 8 p.m. Eastern time.
Business customers can also set up a dedicated account manager through this line, which is useful if you ship regularly and want consistent support. The representative can discuss options like Commercial Plus pricing or negotiated rates for high-volume shippers.
International mail and customs questions
For questions about sending mail or packages outside the United States, or about customs forms and restrictions, the main customer service line (1-800-275-8777) can help. Have the destination country and package contents ready when you call.
USPS also publishes detailed information about international shipping on its website, including which countries accept certain types of mail and what forms are required. For many international questions, the website is faster than calling because the information is already organized by destination.
Frequently Asked Questions
Can I schedule a package pickup by phone?
Yes. Call 1-800-275-8777 and tell the representative you need a pickup. They will ask for your address, the number of packages, and when you want them collected. USPS will pick up packages at no extra charge if you already have postage on them or if you are a regular shipper.
What should I do if I cannot reach anyone after waiting on hold?
If the line disconnects or you reach a message saying all representatives are busy, you can try again later or use the online tools instead. For package tracking, the website is always available. For other issues, calling early in the morning or mid-week usually means shorter waits.
Is there a way to file a complaint about mail service?
Yes. Call 1-800-275-8777 and ask to file a complaint. The representative will document the issue and may open an investigation if it involves repeated problems. You can also file a complaint online through the USPS website under "Contact Us."
Do I need to pay to call USPS customer service?
No. The 1-800 number is toll-free. You will not be charged for calling, though standard phone rates explore if you are using a mobile phone plan with limited minutes.
Can I get a refund for postage over the phone?
You can request a refund or file a claim for lost or damaged mail by phone, but the process usually requires documentation. The representative will explain what you need to provide and how long the review takes, which is typically two to four weeks.
