Proof of address is among the most forged documents, because it is requested everywhere and verified almost nowhere. In most cases it is a genuine bill belonging to somebody else, with the name and address swapped.
Unlike a fraudulent invoice, a forged proof of address rarely starts from scratch. The forger takes a real bill — their own, or one found online — and replaces only the fields they care about: name and address.
That very localised edit is what makes it detectable: the rest of the document is genuine, so every inconsistency concentrates on the edited area.
Large utilities and telecom operators generate bills through industrial pipelines with very stable technical fingerprints: same PDF producer, same embedded fonts, same internal structure month after month.
A document claiming to come from a major supplier whose producer is an office suite, an online converter or a screenshot tool contradicts what it claims to be.
When the name is replaced with an image rather than text, the paste leaves measurable traces.
A document scanned and flattened into an image has no text layer, no fonts and no revision history left. Nearly every check described here becomes inapplicable.
This matters methodologically: the absence of anomalies means nothing when there was nothing to examine. TrustyFile therefore reports such documents as unverifiable rather than giving them a good score by default. Many tools do the opposite, which is misleading.
Asking for the digital original instead of a scan or a photo turns an impossible verification into a possible one. It is the single best move when you are in a position to insist.
