Detect tampered and deepfake Nepal Citizenship Certificate

What a genuine Nepal Citizenship Certificate contains

The certificate prints the citizenship number, issue date, issuing district, full name in Nepali, date of birth, sex, permanent address down to ward level, parents' names, photograph, and the issuing officer's signature and office seal. Dates are written in Bikram Sambat, and an English or AD rendering may appear on translations or newer prints. It carries no expiry, chip, or MRZ.

Layout, handwriting, and typed styles differ by district and era, endorsements and marginal notes are normal, and the English spelling of a name can differ from the passport. Because issue date and birth date are separate fields, date logic carries much of the analysis, alongside seal and signature resolution.

How Nepal Citizenship Certificate forgeries are made

• Bikram Sambat date logic

  BS dates must be possible calendar dates. A month thirteen or a day beyond the end of any month is a gross error that points to retyped or invented fields.

• BS and AD year offset

  Where both calendars are shown, the BS year runs roughly fifty-six to fifty-seven years ahead of the AD year. A gap far outside that range contradicts the document's own dates.

• Issue date against age

  A standard certificate is issued to an adult, so an issue date earlier than the holder's sixteenth birthday contradicts the issuing rules and the story the file tells.

• Seal and signature integrity

  The district office seal and officer signature are pasted in by forgers. Resolution that differs from the surrounding text, or edges that sit apart from the paper texture, localises the paste.

• Devanagari text patching

  Edited names, addresses, and dates leave font weight shifts, baseline breaks, and spacing changes. Genuine endorsements are expected, so the analysis separates them from retyped primary fields.

What TamperCheck checks on a Nepal Citizenship Certificate

TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class.

• Portrait substitution and face-swap analysis

  The document is isolated from whatever it was photographed on, then the portrait region is assessed against the card surface around it. A pasted or generated face rarely matches the substrate it was placed onto.

• Signature forgery analysis

  Signature regions are assessed for ink consistency and for how the stroke sits on the page, which distinguishes a genuine pen stroke from a pasted image of one.

• Date and validity consistency

  Issue, expiry, and period dates are checked against one another and against the file's own creation metadata, which catches backdating and validity extension.

• And many more checks

  The three above are the layers that carry the most weight on a Nepal Citizenship Certificate. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks.

Who verifies a Nepal Citizenship Certificate, and why

Nepali banks, passport offices, and eKYC platforms. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging.

How to verify a Nepal Citizenship Certificate in 4 steps

1. 1

   Photograph the document

   Capture the certificate flat at full resolution, including seals and any marginal notes, so Devanagari text and stamps survive close analysis.

2. 2

   Check the dates

   Confirm every Bikram Sambat date is a possible date, and where an AD year is also shown, that it sits about fifty-six to fifty-seven years behind the BS year.

3. 3

   Weigh issue date and issuer

   Compare the issue date against the holder's age, and the seal and signature against the issuing district named.

4. 4

   Run a forensic check on the file

   TamperCheck runs 200+ forensic checks including date logic checks and seal and patch detection, returning a risk score from 0 to 100 with findings tied to specific regions of the image.
