For USPS tracking support, call the Domestic and International Tracking line at 1-800-222-1811 or 1-800-ASK-USPS (1-800-275-8777), Monday–Friday 8 AM–8:30 PM ET and Saturday 8 AM–6 PM ET, or send an online help request at emailus.usps.com. If a package has stopped moving for 7 days or more, start a Missing Mail search instead, because that’s the channel USPS uses to look for it.
Before you contact anyone, have the tracking number, the mailing date, both addresses and a short description of the package ready. Most agents can see only the same scan history you see online, so the rest of this guide explains which channel can actually act on which problem.
Which USPS Contact Handles Which Tracking Problem?
USPS splits support across several phone lines and online forms. Choosing the right one first saves a second call.
| Problem | Best channel | When to use it |
|---|---|---|
| Tracking shows a status you don’t understand or an issue online tracking doesn’t explain | Tracking line 1-800-222-1811 | Any time during phone hours |
| Package marked delivered but not received, or a delivery complaint | Online help request (emailus.usps.com) or 1-800-ASK-USPS | After checking around the property and with neighbors, usually the next delivery day |
| No movement for a week or more | Missing Mail search (missingmail.usps.com) | Starting 7 days after mailing |
| Need to redirect or stop a package that hasn’t been delivered | USPS Package Intercept (sender’s USPS.com account) | Before it’s out for delivery |
| Insured package lost or damaged | Claim at usps.com/help/claims.htm | Damage right away; loss after the service’s waiting period |
| Problem with your USPS.com account, Click-N-Ship or a claim form | Technical Support 1-800-344-7779 or the chat in the online help form | During phone hours |
Our USPS customer service guide covers the non-tracking lines, including stamps, supplies and TTY relay access.
What Should You Check Before Contacting USPS?
A few minutes with the tracking page often answers the question, and it tells you what to say if you do call. Enter the number at USPS.com, in the USPS Mobile tracking app, or text it to 28777 (2USPS) and read the full scan history, not just the top line.
- “Label Created, Not Yet in System”: The sender bought postage, but USPS hasn’t scanned the package. Only the sender can fix this by handing it off.
- No new scan for a day or two: Packages don’t get scanned on every truck, so gaps are normal. Our guide to USPS tracking that’s not updating explains how long a gap is normal.
- No scan since drop-off: A package left in a collection box or on a counter may not get an acceptance scan until it reaches a processing plant. See why tracking doesn’t update after drop-off.
- Location questions: The USPS tracking map view shows which facility scanned the package last, which helps when you’re asked where it was last seen.
For a full walkthrough of the scan history page and alert options, our complete guide to USPS tracking for every package type starts from the basics.
How Do You Reach a Person About a Tracking Number?
Call 1-800-222-1811 for tracking questions or 1-800-ASK-USPS for general help. Both lines use the same hours: Monday through Friday 8 AM to 8:30 PM Eastern, and Saturday 8 AM to 6 PM Eastern, with no live agents on Sundays or postal holidays.
When you call, enter the tracking number first: the automated system reads back the latest scan, and the agent will ask for the same number. If you’ve already filed an online help request, give the case number so the agent can add to it instead of opening a new one.
How Do You Submit an Online Help Request?
The online form at emailus.usps.com is USPS’s written channel for delivery problems, and it creates a case number you can refer back to. It suits “delivered but not received” cases, damaged packaging, repeated missed deliveries or carrier behavior complaints.
- Go to the USPS Contact Us page and choose the Get Help Online form.
- Pick the category that matches your problem, such as a delivery issue for a missing package.
- Enter the tracking number, the delivery address and a factual description of what tracking shows versus what happened.
- Submit the form and save the case number from the confirmation email.
Keep each request to one package and one problem. If you need to follow up, call 1-800-ASK-USPS with the case number rather than opening a duplicate request.
When Should You Start a Missing Mail Search?
USPS accepts Missing Mail search requests starting 7 days after the mailing date. The search runs through missingmail.usps.com, and USPS sends a confirmation email and periodic updates while it looks.
The request asks for both mailing addresses, the size and type of the box or envelope, the tracking number and mailing date, a description of the contents (brand, model, color or size) and photos that would help someone recognize the item. The more specific the description, the better the chance a mail recovery center can match it.
For packages headed overseas, the process is different: the U.S. sender files an international inquiry, with waiting periods set by service. Our USPS tracking international guide lists those windows and explains why scans thin out after export.
What Can USPS Support Fix, and What Can’t It?
Support agents can explain scans, open a case with the local Post Office and start searches. They can’t move a package faster, change a delivery commitment or add tracking to an item that was mailed without it, such as a First-Class Mail letter without an extra service.
Some fixes belong to the sender. Package Intercept, which redirects or returns a package that isn’t out for delivery yet, is a paid service the sender requests from a USPS.com account, and USPS charges nothing if the intercept fails. Insurance claims can be filed by either the sender or the recipient, but the filer needs the original mailing receipt.
What Tracking Info Should You Have Ready?
- The full tracking number (domestic numbers are usually 20–22 digits; international ones are 13 characters ending in “US”)
- The mailing date and the service used, from the receipt or label record
- Sender and recipient addresses, including apartment or suite numbers
- What the last scan says, with its date, time and city
- A description of the box and contents, plus photos if it was damaged

Frequently Asked Questions
What is the USPS phone number for tracking help?
USPS’s Domestic and International Tracking line is 1-800-222-1811, for package issues beyond what online tracking shows. You can also call 1-800-ASK-USPS (1-800-275-8777). Both lines have live agents Monday through Friday 8 AM to 8:30 PM Eastern and Saturday 8 AM to 6 PM Eastern, and the automated menu reads back the latest scan at any hour.
How long should I wait before asking USPS to search for a package?
USPS accepts a Missing Mail search request starting 7 days after the mailing date. Before that, check the scan history at USPS.com, because short gaps between scans are normal. When you file, include both addresses, the tracking number, the mailing date, the box size and a detailed description of the contents, with photos if you have them.
Can USPS customer service change my package’s delivery address?
Not by phone. Redirecting a package in transit uses USPS Package Intercept, a paid service that only the sender or an authorized representative can request, from a USPS.com account. It works only while the package isn’t out for delivery or already delivered, and USPS doesn’t charge the intercept fee if the redirect doesn’t succeed.
Does USPS have live chat for tracking problems?
USPS’s Get Help Online form at emailus.usps.com includes a chat feature, but USPS describes it as help for technical issues with USPS.com services, such as accounts and Click-N-Ship. For a missing or delayed package, use the written help request, the 1-800-222-1811 tracking line or a Missing Mail search after 7 days.
