User guides / Supplier countries A supplier whose bank account is held in the United Kingdom sees the fields below. The country is chosen on the form, and changing it changes the fields, so a supplier is never asked for a detail their country does not use.

​
Bank details

​
IBAN

An IBAN is optional for the United Kingdom. It is 22 characters and is checked against the ISO 7064 MOD-97 algorithm, which catches a mistyped or transposed digit before the details reach your finance system.

​
Currency

Every account also records its currency. The form opens on GBP, the currency of the United Kingdom, and the supplier changes it for an account held in another currency.

​
Tax and company registrations

After a registration is saved, Coverbase checks it against Companies House and HMRC in the background. That check never blocks the supplier: it annotates the record once it completes, and a reviewer can retry it.

​
Country rules

  • Postal codes are checked against the national format. A postal code that does not match produces a warning, not a rejection.
