MaskAadhaar is an independent private service, not affiliated with UIDAI, the Income Tax Department or the Government of India.
One API for identity documents from India and everywhere else
Mask, extract, verify and redact identifiers from a single key, with the same quota and billing rule on every endpoint.
Aadhaar, PAN, voter ID, driving licence and bank documents for KYC.

Anywhere an ID card, statement or passport is uploaded, stored or passed to another system.
Store a masked Aadhaar and PAN instead of the full numbers, as UIDAI recommends for shared copies.
Swap SSNs, IBANs and card numbers for tokens before a document reaches a model, and keep the context.
Redact payslips, tax forms and ID proofs before they are shared with vendors and reviewers.
Redact the passport MRZ, which repeats the number, name and date of birth in machine-readable form.
Remove card numbers and IBANs from statements and disputes, validated by Luhn and mod-97 checks.
Mask mode keeps the last four digits, so agents can reconcile an account without seeing all of it.
What happens to a document, stated precisely enough to put in a vendor assessment.
Documents are processed in memory and streamed back. No database, no object store, no copy after the request.
PDF text is removed from the content stream, not covered by a box, so copy-paste recovers nothing.
Verhoeff, Luhn, mod-97 and ICAO check digits stop invoice numbers being flagged as IDs.
PDF author and producer, plus image EXIF including GPS, are removed by default.
The API runs in AWS Mumbai (ap-south-1), which matters for data-localisation questions.
Each call is logged with endpoint, size, time and status, never the identifier values themselves.

Aadhaar masking means blacking out the first 8 digits of a 12-digit Aadhaar number, showing only the last 4. UIDAI recommends this when sharing your card with third parties such as landlords, hotels, banks, or employers.

Aadhaar is the official spelling UIDAI uses, but Aadhar, Adhaar and Adhar are all common in everyday writing and in search. They refer to the same twelve-digit number and the same document, and the tools here work identically whichever spelling brought you to them. Misspelled URLs redirect to the right page, so a mistyped or miscopied link still works.

The global endpoints detect and redact passport MRZ lines, payment cards, IBANs, US SSNs, UK National Insurance and NHS numbers, Canadian SINs, Brazilian CPFs, Australian TFNs, South African ID numbers, EU VAT numbers and more. Every identifier with a checksum must pass it before it is redacted. See the full list of identifier types.
