Every upload is analysed by an ensemble of models trained on UK-specific document layouts — HMRC forms, high-street bank statements, PAYE payslips and Home Office share-code letters. The engine cross-checks visual layout against known genuine templates and reconciles numeric fields (running balance, PAYE deductions, NI contributions) against what the maths should produce.
In parallel, TrueDoc reads the PDF's internal metadata — the software that produced it, edit history, embedded fonts and object structure — to spot tell-tale traces of tools commonly used to alter statements and payslips. AI-generated documents are flagged by a dedicated synthetic-content classifier.

Under the Immigration Act 2014, private landlords in England must check that every adult tenant has the right to rent before granting a tenancy. Getting this wrong is not a paperwork slip — the Home Office can issue civil penalties of up to £5,000 per lodger and £10,000 per occupier for a first breach, rising to £10,000 and £20,000 for repeat breaches.
The most common way fraudulent documents enter the rental market is through forged or altered payslips and bank statements used to prove affordability, and manipulated share codes or BRPs used to prove right to rent. TrueDoc gives letting agents, landlords and guarantors a fast, free way to sanity-check what a prospective tenant has sent them before signing.
These are the fastest checks a reviewer can run before escalating a document. TrueDoc runs every one of them automatically.
The first two letters must be one of the ranges published by HMRC. Prefixes like BG, GB, NK, KN, TN, NT and ZZ are never issued.
Format is three digits + '/' + up to ten alphanumerics (e.g. 120/AB12345). Employer office number should exist in HMRC's register.
Every UK sort code maps to a real bank via the ISCD reference. A code that doesn't resolve is almost always fabricated.
On a genuine statement, opening balance ± every transaction = closing balance to the penny. Forged statements often have a rounding gap.
Genuine HMRC and high-street bank PDFs are produced by known software. A statement 'produced by Microsoft Word' or 'Photoshop' is a strong red flag.
P60s, SA302s and BRP letters use specific embedded fonts. Substituted fonts often reveal edits that layout alone would hide.
Payslips, bank statements, HMRC forms, right-to-rent documents and IDs — all in one place. No card required to start.
