To confirm someone’s identity to meet JMLSG and UK regulator guidelines a verification known as a 2+2 is the expectation. This involved taking two pieces of information about the person and matching them against two different data sources. Typically for the UK this would be name and address against one source (such as electoral register) and name and date of birth against another source (such as credit record). The data sources used and matching terms defined will differ from country to country depending on the service and data available.
