What is ORIAS?

ORIAS is the French register of credit providers and banks, and the number on it is how you tell two similar looking lenders apart. BNP Paribas shows 07 022 735, and Hello bank! shows the same identifier, 07 022 735, with Hello bank! Pro listing 07 022 735 too. Cetelem has its own, 07 023 128, and Meilleurtaux another, 07 022 955, so matching numbers are a useful hint of shared backing.
