To find your USPS tracking number, check your mailing receipt, online postage record, or retailer’s shipment confirmation. If someone else mailed the item, ask the sender. Enter the number on the official USPS Tracking page to see the latest recorded status and available delivery information.
USPS Tracking reports scan events. It does not show a live map of your package or guarantee a delivery time. The next step depends on whether USPS has received the item, is transporting it, or has recorded a delivery attempt.

Where to find your USPS tracking number
Start with the record you created when you purchased postage or shipped the item. USPS’s tracking-number help page identifies these places to check.
| Your situation | Check first | What to look for |
|---|---|---|
| You mailed it at a Post Office | Mailing or sales receipt | The tracking or article number associated with that item |
| You used a self-service kiosk | Printed receipt or eReceipt | The package’s tracking entry |
| You bought postage online | Click-N-Ship or the label provider’s shipment record | The number attached to the purchased label |
| You ordered from a retailer | Shipment email or order’s shipping details | The USPS number for that parcel |
| You have the package or a label image | Shipping label | The number below the tracking barcode |
Receipt layouts vary. Look for the tracking entry rather than assuming every receipt places it at the bottom. A receipt can contain several numbers, so match the entry to the package and service.
If you lost the receipt
Check email, saved label files, and the account used to buy postage. Ask the sender for the shipment record. USPS says local Post Offices and Care Center agents cannot recover lost tracking numbers.
If you already use Informed Delivery, check whether the expected package appears in your dashboard. The service can associate eligible packages with your verified address. It is not a guarantee that every parcel will appear or that a newly created account will recover an old shipment.
Not every mailpiece has tracking. Ordinary First-Class Mail letters, flats, and postcards do not automatically come with a package-style tracking number. Keep that distinction in mind before searching for a number that was never assigned.
What a USPS tracking number looks like
Many domestic package numbers contain 20–22 digits, but formats vary by service. USPS examples include long numeric codes and 13-character codes made up of two letters, nine digits, and two final letters. Some US-origin international examples end in US.
Priority Mail Express can use different formats, so don’t reject a number just because it differs from a domestic package code you used before. Copy the complete identifier from the receipt or label. Do not shorten it to fit a guessed digit count.
How to track a USPS package
- Open the official USPS Tracking tool.
- Paste the full number into the tracking field and submit. Remove accidental punctuation or copied text.
- Read the latest event, its date and location, and any delivery estimate or instructions.
- Save the number with your shipment record and request text or email updates if offered.
USPS’s receiving page lets you check multiple numbers at once, with a field for up to 35. When reviewing the results, keep each number tied to its own package.
You can also text a tracking number to 28777 (2USPS). Standard message and data rates may apply. Sending the number alone requests the current status; future alerts require the appropriate notification selection or keyword. The USPS Mobile app provides another way to check.
Switching from the website to a text message does not create a new physical scan. If no new event occurs, another notification channel may show the same information.
Read the status before deciding what to do
Use the latest event and the USPS tracking status together. The table summarizes common situations.
| Status or situation | What it indicates | Next step |
|---|---|---|
| Label created | Label data exists; USPS receipt is not shown | Ask the sender about handoff |
| Shipping partner awaiting USPS | Another company is handling the parcel | Ask the shipper about transfer |
| In transit | Processing or transportation continues | Compare progress with service expectations |
| Out for delivery | The local office prepared it for delivery today | If undelivered after one full postal business day, submit a service request |
| Delivered | USPS recorded a delivery time and location | Check delivery spots and building staff |
| Notice left | Delivery needs follow-up | Follow pickup or redelivery directions |
If a delivered package remains missing after more than one postal business day, USPS directs customers to submit a service request for eligible items. Check the recorded location first, including parcel lockers and building management where relevant.
A number that does not work differs from a status that has not changed
If USPS does not recognize the number, compare it with the original label or shipment record. Confirm the carrier, the full identifier, and whether the sender has created a USPS shipment. Ask the sender to correct a mismatch.
If the number works but its history has stopped changing, check the mail service and delivery expectations. A gap between events does not by itself prove loss. Avoid applying a universal waiting period to every service and status.
For an unresolved delay, use the steps shown in the tracking result. Missing Mail searches can generally begin seven days after mailing, subject to the mail class and search requirements. Count from mailing, not the last tracking update. Our guide to lost USPS mail and packages explains how to recover it.
A service request, a Missing Mail search, and an insurance claim serve different purposes. A stalled tracking page does not automatically make a shipment eligible for reimbursement.
Save tracking records before access expires
USPS lists different storage periods for tracking records.
| Service or record category | Standard record period |
|---|---|
| USPS Tracking service | 120 days |
| Signature Confirmation | 1 year |
| Priority Mail Express, Certified Mail, and Registered Mail | 2 years |
These are service-specific periods. Do not assume an ordinary Ground Advantage or Priority Mail tracking history remains available for one or two years. Save the receipt and relevant delivery records while you can access them.
USPS Tracking Plus is a paid option for extending access to eligible histories. Options can extend access to 10 years for domestic products and 7 years for eligible international products. Review the expiration date and available options on the item’s tracking page. USPS says you can purchase it as long as the tracking history remains accessible.
Tracking Plus concerns records. It does not make a package move faster, add live location data, or turn an ordinary scan into a recipient signature. Select services appropriate to your proof-of-delivery needs when mailing.
Check delivery texts through USPS directly
If a message asks you to follow an unfamiliar link or pay to resolve a delivery issue, open USPS.com yourself and check the known tracking number. Do not use the message as proof that a shipment problem exists.
The US Postal Inspection Service identifies unsolicited package-tracking texts as a common smishing tactic. Use your sender records and the official tracking result to decide what action, if any, the shipment needs.
Track the right shipment when using a virtual mailbox
When you send a package to a virtual mailbox, carrier delivery and account check-in are separate events. PostScan Mail receives the item and uploads its image after processing. A carrier delivery scan does not itself confirm that the item has appeared in your account.
If you later request package forwarding, the onward shipment has its own carrier record. Keep the retailer-to-mailbox tracking number separate from the forwarding number.
For example, a retailer parcel can show delivery to your receiving facility while you are still waiting for check-in. Check the facility’s processing status for that stage. After dispatch, use the onward carrier’s number to follow the new shipment. Rechecking the original number will only show the first delivery as completed.
Save both numbers with the corresponding order and mailbox item. If you need a receiving address, compare PostScan Mail locations and confirm the facility’s services before ordering. USPS Tracking follows the carrier journey; your mailbox account handles requests after receipt.
