Answers to Questions

What is a BBAN?

A BBAN (Basic Bank Account Number) is composed of 10 to 30 characters, depending on countries, corresponding to the bank codes (including the account number) and a checksum key.

How to verify an BBAN number? (Validity check)

The algorithm checks the BBAN key via a modulo 97href:

Consider the RIB: 12345 12345 0123456789AZ 96

Step 1: Remove the key BBAN code.

The key is composed of the last 2 digits: 96. The rest of the calculation is done with 12345 12345 0123456789AZ.

Step 2: replace any lettershref by figures in the table

A, J1
B, K, S2
C, L, T3
D, M, U4
E, N, V5
F, O, W6
G, P, X7
H, Q, Y8
I, R, Z9

The BBAN becomes 12345123450123456789AZ

Step 3: Calculate the value of the result modulo 97href.

$$ 12345123450123456789AZ \mod 97 \equiv 96 $$

The checksum key is therefore 96 (the key removed at the beginning), the BBAN is valid.

To make this modulo calculation you must use a calculator that accepts calculation with large numbers (arbitrary precision) as proposed on dCode.
