Most Indian identifiers have a structure you can check before a form is submitted. This page reads six of them, tells which one you pasted from its shape, names each part, and tests the check digit where one exists and is published.
| ID | Length | Built from | Check digit tested here |
|---|---|---|---|
| GSTIN | 15 | State code, PAN, entity number, Z, check | Yes, base 36 |
| PAN | 10 | Series, holder type, name initial, number, check | No, formula not published |
| Aadhaar | 12 digits | 11 random digits and a check | Yes, Verhoeff |
| IFSC | 11 | Bank code, 0, branch code | None defined |
| UPI ID | Varies | Name, @, handle | None defined |
| PIN code | 6 digits | Region, sub-region, district, post office | None defined |
What a pass does not mean matters more. A correct format and check digit prove that the number was copied without a typo. They do not prove it was ever issued, that it is still active, or that it belongs to the person or business in front of you. Each result links to the official service that answers that question: Search Taxpayer on the GST portal, Verify Your PAN on the Income Tax e-filing portal, Verify Aadhaar on UIDAI's myAadhaar, the RBI's IFSC search, and India Post's Know Your PIN Code. For a UPI ID there is no public lookup, and the name your UPI app shows before you pay is the check.
The rest of the article, and all 6 questions about India ID Number Validator, are on the India ID Number Validator page.
No. A correct format and check digit only prove the number was copied without a typo. Whether it was issued, is active, or belongs to a given person or business is known only to the issuer: use Search Taxpayer on the GST portal, Verify Your PAN on the Income Tax e-filing portal, or Verify Aadhaar on UIDAI's myAadhaar.
Each of the first 14 characters becomes a number from 0 to 35 (digits, then A as 10 up to Z as 35). Alternate characters are multiplied by 1 and 2, each product adds its quotient and remainder by 36 to a total, and the check character is 36 minus the total's remainder, modulo 36. The page shows every step.
The twelfth digit of an Aadhaar number is a Verhoeff check digit, the scheme UIDAI's numbering design chose because it catches every single wrong digit and every swap of two neighbouring digits. Numbers starting with 0 or 1 are reserved, so a resident's Aadhaar begins with 2 to 9. Checking needs no internet connection.
No. Every check runs in your browser and the page makes no network request with what you type. An Aadhaar number is shown masked to its last four digits, nothing typed is kept in browser storage, and share links never include an Aadhaar number, PAN, GSTIN or UPI ID.
