Package Tracker: Identify Your Tracking Number and Open the Official Carrier Page
Paste the tracking number from your Temu, SHEIN, AliExpress or Amazon order. We tell you what kind of number it is, validate the check digit on international postal numbers, and open the official carrier page with the number already copied.
Runs in your browser: we don’t send or store what you type.
How it works
- Paste the number exactly as it appears in your order (spaces are fine).
- Check the detected format. For international postal numbers (the Universal Postal Union’s S10 format, like
RR123456785GB) we verify the check digit and show the issuing country. - Open the carrier. The button copies the number to your clipboard and opens the carrier’s official tracking page, so you just paste it.
We don’t fetch the shipment status ourselves: no carrier we checked documents a public deep link for tracking numbers, so we send you to the official page rather than show third-party data that may be stale.
Formats it recognizes
| Format | What it looks like | Used by |
|---|---|---|
| UPU S10 (international postal) | 2 letters + 9 digits + 2 letters (13 characters) | National posts: USPS, China Post, Royal Mail… |
| UPS | Starts with “1Z”, 18 characters | UPS |
USPS, FedEx, DHL, Amazon and OnTrac don’t publish a complete official format for their numbers, so if yours isn’t recognized, pick the carrier your order page names from the list.
FAQ
How do I know which carrier has my package?
Your order page usually names the carrier next to the tracking number. If you only have the number, this tool tells you whether it’s an international postal (S10) or a UPS number.
What do the two letters at the end mean?
In the UPU S10 format, the last two letters are the country code of the postal operator that issued the number (for example CN for China). The first two letters identify the service.
It says the check digit is wrong. Is my number fake?
Most likely it was mistyped. Check look-alike characters (O and 0, I and 1). If the store shows it that way, ask the store.
Why don’t you show the tracking status here?
Because we couldn’t verify an official link that allows it. We’d rather send you to the official source than show third-party data.
Do you store the numbers I paste?
No. Detection runs in your browser.
