What South Africa DHA Fingerprint Match Verification validates

Verifies provided fingerprint images against the Department of Home Affairs fingerprint register. Didit exposes it through a single endpoint so you can verify the submitted data against authoritative government data sources and receive a structured, normalized result — not a raw registry dump you have to parse yourself.

A conclusive response returns the matched source_data and a per-field validation block, so your risk engine gets a clear, machine-readable verdict.

Why it matters

Government-held records are the strongest authoritative source for confirming a person exists at the stated identity.

For regulated businesses in South Africa — fintechs, crypto platforms, lenders, marketplaces, and gaming operators — checking against an authoritative source produces a defensible, auditable record that identity was confirmed at the source, not merely captured from a form or a photo.
