@Gargron Are they saying that many of us have the same bank account number and its only the sort code that divides them.

@Gargron

This is why I feel that all account identifiers need a checksum - like in IBAN.

A pity that my country's banks do not support IBANs.

@gargron that's why IBAN uses a 2-digit checksum. It is quite unlikely that you hit another valid code with changing two digits or less.
