## Questions

### What does the IBAN check test?

Three things: that the length matches the country in the SWIFT IBAN Registry, that each position holds a digit or letter where that country's layout says it should, and that the two check digits work out under the ISO 7064 MOD 97-10 rule. Together they catch almost every typing mistake, including two swapped digits.

### Does a valid IBAN mean the account exists?

No. A valid IBAN is well formed; only the bank can say whether the account is open and whose it is. In the euro area and the UK, a payee-name check (Verification of Payee, or Confirmation of Payee in the UK) is done by your bank when you pay.

### Do the United States and Canada use IBANs?

No. Neither is in the IBAN Registry: US accounts are paid with a routing number and account number, Canadian ones with an institution number, transit number and account number. For an international transfer to either, the bank also asks for a SWIFT/BIC code.

### What is a BIC?

A bank's international identifier, also called a SWIFT code: 8 or 11 characters made of a 4-character bank code, a 2-letter country, a 2-character location and an optional 3-character branch. The checker tests that shape; it cannot tell whether a BIC is issued.
