Prove

Overview

Prove, founded in 2008, provides phone-centric identity verification and authentication, using phone number intelligence and possession signals to verify and authenticate users with low friction. It is strongest in US financial services, where phone-based trust streamlines onboarding. See all identity verification vendors for alternatives.

What it is good at

Phone-based verification and authentication that cut onboarding friction are the strengths, backed by deep phone-intelligence data and possession signals. The same signals support ongoing authentication, so Prove spans both verify and login, which is unusual in this category and valuable for banks fighting drop-off. Because possession and phone-tenure signals can verify a returning user almost invisibly, Prove is attractive for high-friction flows like account recovery and step-up where document re-capture would lose customers.

Where it falls short

Coverage and accuracy depend on phone-intelligence data, which varies by market and is weaker outside the US. It is not a document-first verifier, so buyers needing global document and biometric checks will pair it with another vendor. Pricing is quote-based. Outside its strongest US data markets, coverage thins and the model leans more on supplementary checks, so a global rollout cannot rely on phone intelligence alone.

Pricing

Quote-based, structured around verification and authentication volume. Model your real volume with the TCO calculator. Costs are typically negotiated against verification and authentication volume, with no public list price.

Best for, and who should look elsewhere

Choose Prove when phone-centric, low-friction identity and authentication fit your users, especially in US finance. For document-first verification consider Onfido; for fraud and device signals consider Sardine; for US synthetic-fraud detection consider SentiLink.

Bottom line

A strong phone-centric identity and authentication choice, especially for US financial services.
