Best KYC API Providers
Compared (2026)

How to read this list of KYC providers

There are a lot of KYC solutions on the market, and more arrive every year, because the rules keep expanding and every new rule creates something to sell. That growth is why this list runs to 125 names, and why they are harder to compare than they look.

Some vendors sell ready-made KYC software: a dashboard your compliance team logs into, runs checks in and works a review queue. Others sell an API you build into your own onboarding, so the check happens where your signup happens. Plenty sell both. Some also cover KYB, verifying businesses as well as people, and some only do one of the two properly.

Coverage splits them again. A few providers are built around a single country and know its registry and its identity scheme inside out. Others work worldwide, at a shallower depth. Both are useful, depending on where your customers actually are.

The biggest difference is data quality, and it can vary enormously. Two providers will list the same country and return very different answers. We supply the underlying business data to 34% of the providers on this list, which gives us a good view of who delivers quality where, and who does not.

Which one fits you depends on who you are verifying, the markets you need, your budget and how you want to integrate. Set those four filters in the tool below and it will shortlist the providers that match.

What is KYC? (And how is it different from KYB?)

KYC (Know Your Customer) is the regulatory requirement for verifying the identity of customers — typically individuals — before they can use a financial product. KYB (Know Your Business) is the equivalent for verifying the identity, ownership and standing of a company. Both are part of a broader AML (Anti-Money-Laundering) programme that also includes sanctions screening, PEP screening and ongoing monitoring after onboarding.

The KYC market has fragmented into five distinct capability areas. Most mid-market compliance stacks combine two or three of them; banks typically run an enterprise CLM platform that orchestrates specialists.

Business KYC: when the customer is a company

Business KYC is what most teams call it before they meet the industry term. The regulation treats it as its own discipline — KYB — because verifying a company is a different job from verifying a person: there is no document to photograph and no face to match, and the thing you are checking is a registry filing that may be months out of date.

A business KYC check confirms the entity exists and is still active, pulls its registered address, officers and filing history, and walks the ownership chain to the people who ultimately control it. In the directory above, the providers marked KYB do this; the ones marked KYC verify individuals. Most regulated platforms need both, and buy them from different vendors.
