Is it valid? Try our bank account and sort code checker
Read time: 3 minsLast updated: 31 December 2024
In the UK and Ireland, each bank account number is created using a unique algorithm specific to each bank, and sometimes to individual branches within a bank. These numbers are not generated sequentially; the generation system is designed to minimize similarities that could lead to errors in transferring money to the wrong account.
Bank Account & Sort Code Checker
How does it work?
Banks use "modulo" and "double-alternate" modulus checker algorithms, along with specific "weights" to perform calculations. These methods help ensure account numbers are entered correctly by identifying common errors such as swapped digits.
As new banks emerge and new sort codes are assigned, the relevant algorithms must be shared with other banks. Mintly keeps its system up-to-date with the latest algorithms, providing customers with current data.
