Shipping Carrier Identifier
Enter a tracking number to see which carrier's format it matches. This is a best guess based on the number's pattern, not a lookup in any carrier's system.

What this carrier identifier can and cannot tell you
Online shops sometimes send a bare tracking number without saying who is delivering the parcel. This page compares the number's format with the patterns used by ten carriers (UPS, FedEx, USPS, DHL, Amazon Logistics, China Post / EMS, SF Express, YTO Express, ZTO Express and Royal Mail) and suggests which one probably issued it, with a link to that carrier's own tracking page. It is pattern-based guessing: the page never contacts a carrier, so it cannot confirm that a number exists or show where a parcel is. Two extra tabs cover a carrier reference list and rough delivery-time ranges between six regions.
How to use it
- Paste the number into the box and press Identify or Enter. Spaces and hyphens are removed and letters are converted to capitals before matching.
- Read the result card. One match gives a single carrier; several matches mean the format is shared, and each gets its own Track Package link.
- Click a Track Package link to open the carrier's official site with the number filled in, where the real status is shown.
- For many parcels, open Bulk Identifier, paste one number per line and press Identify All; each line links to the first matching carrier.
- Use Carrier Directory to see each carrier's website and the pattern the page checks, or Shipping Estimator to compare typical transit times between two regions.
How the matching works
Each carrier has one or two regular expressions, and the number is tested against all of them. Some formats are distinctive: UPS numbers usually start with 1Z followed by 16 letters and digits, Amazon Logistics uses TBA plus 12 or 13 digits, SF Express SF plus 13 digits and YTO YT plus 13 digits. International postal items follow the Universal Postal Union pattern of two letters, nine digits and a two-letter country code, so …CN points to China Post, …US to USPS and …GB to Royal Mail. Purely numeric numbers are the weak spot: the FedEx rule accepts any 12 to 22 digits, ZTO any 13 to 15 digits and DHL any 10 or 11 digits, so a 13-digit number matches both FedEx and ZTO, and a 22-digit USPS number starting 94 also matches FedEx. Carriers change their formats, and many regional couriers are not covered at all, so treat a match as a hint.
Everything runs in your browser and nothing you type is stored or sent anywhere. The only time a number leaves your device is when you click a tracking link, which passes the number to that carrier's website in the address. The Amazon link opens your Amazon order history, which needs you to be signed in.
About the delivery-time estimates
The Shipping Estimator shows fixed day ranges stored in the page for common services, for example DHL Express at 3-5 days between the United States and China, or Royal Mail 1st Class at 1-2 days within the UK. Choosing the same origin and destination gives domestic services. A reversed route reuses the data for the opposite direction when only that one is listed, and routes not in the table fall back to a generic DHL, FedEx and UPS list. These are rough typical times, not quotes: they ignore customs clearance, remote areas, holidays and the exact service you buy, and they include no prices.
Frequently asked questions
Why does my number match two carriers?
Several carriers use plain digit strings of similar length. The tool lists every carrier whose pattern fits; the sender's confirmation email or the label usually settles it.
Why is my number not recognised?
It may come from a carrier the page does not cover, such as a regional courier, or contain a typo. Copy it again from the original message and check with the seller if needed.
Can this page show where my parcel is?
No. It only identifies the likely carrier. Live status and delivery updates come from the carrier's own tracking page, reached through the links.
Is it safe to paste my tracking number here?
Yes. Matching happens locally in your browser and nothing is saved. A tracking number is only sent to a carrier's website if you click its tracking link.
