[User guides](/user-guides/overview) Coverbase collects supplier bank details, addresses, and tax registrations according to the country the details belong to. Each country has its own set of fields, its own formats, and its own checks, and this section documents what each one asks for. Use these pages when you want to know what a supplier in a given country will be asked for before you send them a request, or when you are looking at a warning on a submitted record and want to know what produced it. For how collection and review work, see the [Supplier information guide](/user-guides/supplier-information). ## Countries | Country | IBAN | Tax registrations | Rule confidence | |
