Advanced tools
TypeScript class that validates UK bank account details using the modulus checking algorithm.
It only users vanilla typescript, and the 'fs' file-loading library.
From time to time, Vocalink updates the txt files here mapping sort-code ranges to validation weights. We currently use v7-90 (valid from 17 August 2024).
import ModulusChecker from 'UKModulusCheck';
let checker = new ModulusCheck()
checker.validate({ sortCode: '180002', accountNumber: '00000190'})
# true
checker.validate({ sortCode: '938063', accountNumber: '15763217'})
# false
', accountNumber: '', expectedResult: true
[todo add to npm and add]
This specification details logic to differentiate valid vs. invalid pairs of sort-code and account number.
A mathematical algorithm compares the two values, and check if the two can be paired together legitimately.
This page details any changes to the specification.
