Detect tampered and deepfake Business Registration
A fake business registration certificate usually fails on its number rather than its appearance. This is the first document a payment provider or marketplace asks a merchant for, so it is the first thing manufactured by anyone who wants a payout account for a business that does not trade. The common approach borrows a live registration number from a company in good standing and prints a different entity name above it, leaving everything else on the certificate authentic.

What a genuine business registration document contains
A business registration certificate records the registration number in the registry's own format, the legal name of the entity and any trading name it operates under, the entity type, the date of registration or incorporation, and the registered address. Most registries add the authorised or paid-up capital, the name of the registrar who signed, the date of issue, and a stamp or seal. Newer certificates carry a QR code or a verification reference that resolves back to the registry's own record of the same entity.
The registration number is the field the rest hangs off. In most registries it encodes the jurisdiction, the office, and the year of registration, so its format has to agree with the date printed further down the page. The entity type has to match the suffix carried by the legal name, the issue date cannot precede the registration date, and the registered address has to be the one the registry holds. A borrowed number brings all of those with it, and the swapped name then contradicts every one.
How business registration document forgeries are made
Number transplanted from a trading company
A registration number belonging to a real, active business is printed under a different entity name. The number survives a format check and sometimes a lookup, and the mismatch only surfaces when the name returned by the registry is compared against the name on the page.
Entity name substitution
The legal or trading name on a genuine certificate is overwritten so an unregistered merchant can present someone else's registration as their own. A replaced name rarely shares the kerning and baseline of the line it sits on, and its glyphs carry a different compression history from the text beside it.
Incorporation date pulled back
The registration date is moved earlier to clear a minimum-trading-history rule at a payment provider or lender. It is one of the cheapest edits available and one of the most consequential, because tenure is what many onboarding policies use in place of underwriting.
Registry stamp and seal reproduction
The registrar's stamp is rebuilt or scanned in and applied to a template. Reproduced stamps come out uniformly inked, where a real rubber stamp varies in coverage across its face and picks up the texture of the paper it was pressed onto.
Address and capital edits
The registered address is changed to a serviced office in a more favourable jurisdiction, or the paid-up capital is raised so the entity clears a size threshold. Both edits leave a field whose rendering differs from its neighbours on a page that is otherwise entirely genuine.
Certificates sold as a service
Complete registrations are produced to order from registry templates, with the number, name, and dates chosen to be self-consistent. Since nothing was edited, there is nothing for a field comparison to find, and detection falls to substrate, print, and generation analysis.
What TamperCheck checks on a business registration document
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.
Embossed seal analysis
A physically embossed seal deforms the paper it sits on. A seal that was scanned and reprinted is flat, and the two separate cleanly under analysis even when they are hard to tell apart by eye.
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.
Reference and document number checks
Document, account, and reference numbers are checked for issuer format conformance and against every other place the same value appears on the page.
And many more checks
The three above are the layers that carry the most weight on a business registration document. 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 business registration document, and why
Payment providers, marketplaces, and banks onboarding business customers. 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 business registration document in 4 steps
Check the fields against each other
Read registration number, entity name, and incorporation date together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original.
Inspect the file metadata
Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look.
Ask for a second document
Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare.
Run a forensic check
Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on a business registration document and returns a risk score from 0 to 100 within seconds, at $0.50 per document.
Frequently asked questions
How do I verify a business registration certificate?
Search the registry that issued it for the registration number and confirm the entity name, type, registration date, and registered address the registry returns are the ones printed on the certificate. Scan any QR or verification reference and check it resolves to the same record. Then examine the file itself, because a certificate copied from a real record and reprinted will pass every one of those checks.
How do payment providers check business registration documents?
Payment providers run the registration number against a registry or a KYB data vendor, match the entity name and directors against the person applying for the account, and screen those names for sanctions and adverse media. The certificate itself is often the weakest link in that chain, because it is uploaded as an image and reviewed by eye rather than analysed.
What does a forged business registration certificate look like?
It usually looks correct, which is the point. The visible tells are a registration number whose format does not fit the stated year or office, an entity type that contradicts the suffix on the legal name, a stamp with unnaturally even ink coverage, and a single field whose text is fractionally crisper or softer than the lines around it.
How much does it cost to check a business registration document?
TamperCheck charges $0.50 per document, with no subscription and no minimum volume. A certificate uploaded as a PDF, scan, or phone photo comes back with a risk score from 0 to 100 and findings tied to the specific regions of the page that failed, usually inside a minute, through one REST endpoint.
TamperCheck analyses business registration uploads with a hybrid forensic and AI pipeline tuned for this document class. Upload endpoints accept PDF and common image formats; class is inferred automatically. See the API & MCP documentation for authentication, async jobs, and webhooks.
