Verify customer information using a wealth of data sources.

We use many data sources to verify the information your customers provide. We correlate data across credit bureaus, motor vehicle records, address histories, watchlists, and other records in order to provide a superior solution to single-source verification services.

Learn about our ID verification

Authenticate your users with Knowledge-Based Authentication

We provide a series of questions to which only your customer knows the answer using information separate from someone’s identity. This provides a better, practical solution to photo ID verification because it is difficult to know correct answers to these questions unless you are actually the person.

Comply with Know Your Customer and anti-money laundering regulations

As part of every verification, we instantly scan dozens of government watchlists and red flag lists to protect your business from wanted individuals. We can optionally proactively scan your entire user base every time the list changes and inform you if anything changes.
