Aadhaar Number Masker

Mask the 12-digit Aadhaar number in your scan or photo before sharing — auto-detected with on-device OCR, blacked out permanently. Free, private, nothing uploaded.

Your files never leave your device — all processing happens in your browser.
🔒 We can't see your documents — ever.
Your photo or file never reaches our servers. Everything happens 100% in your browser, on your own phone or computer — it all stays with you.
What this tool does: detects the Aadhaar number format in your scan and blacks it out. What it does not do: verify identity, connect to UIDAI or any government database, or fetch any data. It is not affiliated with UIDAI. You must review every detection before downloading — OCR can miss numbers on blurry scans.

Why You Should Mask Your Aadhaar Number Before Sharing

Your Aadhaar number opens doors — bank accounts, SIM cards, government benefits. That is exactly why a photocopy of your Aadhaar floating around on WhatsApp is dangerous: the full 12-digit number, name, address and photo in one image is an identity-theft kit. UIDAI itself advises sharing a masked Aadhaar — one showing only the last four digits — wherever the full number is not required.

The official route is UIDAI's myAadhaar portal: OTP on your registered mobile, tick "Do you want a masked Aadhaar?", download. But that only helps when you are downloading fresh. When you already have a scan or photo of your Aadhaar — the one the hotel, the broker or the HR portal asked for — you need to mask the number on that file before sending it. That is what this page does, entirely on your device.

How to mask the Aadhaar number in a scan

  1. Drop your scan or photo onto the page. JPG, PNG, PDF or HEIC — it is read locally, never uploaded.
  2. Let the on-device OCR scan it. The tool reads the text in your scan and keeps only 12-digit numbers that pass the Verhoeff checksum — the check-digit system behind real Aadhaar numbers.
  3. Review every detection. Each found number is listed with a preview of exactly what will be blacked out. Tick the ones to mask — this step is mandatory, because OCR can miss numbers on blurry scans.
  4. Download the masked file. The numbers are covered with solid black boxes, permanently. Look at the result once yourself before sharing it.

Masked Aadhaar: where it works and where it doesn't

A masked scan is accepted for most everyday identity checks: hotel check-ins, airport and railway verification, private-company KYC, job verification, SIM registration. But Indian law still demands the full Aadhaar number in several places — opening a bank account, government welfare schemes, income-tax filing, PAN services. Masking is for the casual-sharing moments, not a replacement for the official document where the law requires it.

Official vs this tool. UIDAI's myAadhaar portal issues an official masked Aadhaar (OTP-verified). This tool masks the number on your existing scans for safe sharing — it is not affiliated with UIDAI, does not verify identity, and does not replace the official document.

Why "never upload" matters most here

Masking your Aadhaar on a random website is self-defeating: you hand your full, unmasked identity document to a server you do not control, hoping it comes back masked. The only safe way to mask is locally — which is why this tool downloads its OCR engine to your browser and processes everything on your device. Your scan never travels anywhere.

The bottom line

Share the masked copy, keep the original private. Mask before you send — on your own device, with your own eyes on the result.

Tips

  • Sharp scans detect best. Photograph straight-on in good light — blurry or tilted scans hide digits from OCR.
  • Check the whole file. Aadhaar numbers can appear twice (front and back). The tool scans everything it can read.
  • PDFs work too. Multi-page PDF scans are checked page by page.
  • When in doubt, use UIDAI. For an officially issued masked Aadhaar, download from myAadhaar with OTP.

Common uses

  • WhatsApp KYC requests — mask before sending to brokers, HR or landlords.
  • Hotel check-ins — share the masked copy, keep the original.
  • Online forms — where the full number is not required.
  • Old scans in email — mask before forwarding.

Frequently asked questions

Is Aadhaar Number Masker free to use without signup?

Yes. EzySize’s Aadhaar Number Masker tool is free to use without creating an account. Advertising may appear on this page; the tool remains free to use. Use the controls above and check the result against your requirements.

How can I mask my Aadhaar number in a photo?

Drop the photo or scan onto this page. On-device OCR finds the 12-digit Aadhaar number, you review each detection, and the tool blacks the number out permanently. Download the masked file and share that instead of the original.

What is a masked Aadhaar?

A masked Aadhaar shows only the last 4 digits of the 12-digit number (XXXX XXXX 1234). UIDAI issues official masked Aadhaar via its portal; this tool achieves the same visual result on your own existing scans by blacking out the number before you share the file.

Is a masked Aadhaar valid as ID proof?

For most everyday verifications — hotel check-ins, private company KYC, SIM registration — yes. But where the full number is legally required (bank accounts, government schemes, income tax, PAN services), you will still need the regular Aadhaar.

How do I download an official masked Aadhaar from UIDAI?

Go to myaadhaar.uidai.gov.in, choose Download Aadhaar, enter your Aadhaar/VID/EID and captcha, tick "Do you want a masked Aadhaar?", verify the OTP sent to your registered mobile, and download the password-protected PDF. Use the official route when you need an officially issued document.

Is it safe to upload my Aadhaar scan to a website for masking?

With most sites, you are trusting a stranger's server with your identity document. This tool never uploads anything — the OCR and masking run entirely in your browser on your own device, so there is no server that could leak, store or misuse your scan.

Does this tool verify my Aadhaar number?

No. It only detects the number's format (12 digits passing the Verhoeff check digit) and masks it. It does not verify identity, does not connect to UIDAI or any government database, and fetches no data about you.

What if the tool misses a number on my scan?

That is why the review step is mandatory: every detection is shown with a preview, and you must confirm each mask before downloading. OCR can miss numbers on blurry, tilted or low-contrast scans — always look at the final file yourself before sharing it.

Can I mask the Aadhaar number in a PDF scan?

Yes — upload the PDF and each page is scanned. The masked pages are rebuilt into a new PDF for download. (For multi-page PDFs the scan takes a little longer; progress is shown.)

How does the tool find the Aadhaar number?

It runs optical character recognition on your scan, groups digit sequences, and keeps only 12-digit numbers that pass the Verhoeff checksum — the check-digit system UIDAI uses for Aadhaar numbers. Random 12-digit strings that fail the check are ignored.

Where can I use a masked Aadhaar?

Hotels, airports and railway verification, private-company KYC, job verification, SIM registration and general ID proof with private services. For bank accounts, government welfare schemes, tax filing and PAN services, the full Aadhaar is still required.

Will masking work on a blurry photo of my Aadhaar?

Maybe not — OCR needs readable digits. If the scan is blurry, tilted or shadowed, detections may be missed. Retake the photo in good light, straight-on and sharp, for reliable detection. And always verify the masked result visually.

Is this tool affiliated with UIDAI?

No. This is an independent privacy tool by EzySize with no connection to UIDAI or the government. For an officially issued masked Aadhaar, use UIDAI's myAadhaar portal.
