ibankit

A library for generation and validation of the International Bank Account Numbers (IBAN ISO_13616) and Business Identifier Codes (BIC ISO_9362).

Key Features

• Drop in replacable with iban-js
• Currently conformant with Version 80 of the IBAN registry
• Decodes bank, branch and account numbers from IBAN
• Supports random BBAN / IBAN generation for testing
• Has BIC validation as a bonus
• Supports validation of National Check Digits if part of BBAN format
• This library provides full TypesScript support
• No external dependancies

Iban quick examples:

// How to generate Iban
const iban = new IbanBuilder()
  .countryCode(CountryCode.AT)
  .bankCode("19043")
  .accountNumber("00234573201")
  .build();

// How to create Iban object from String
const iban = new IBAN("DE89370400440532013000");

// The library ignores spaces in IBANs, this is valid
const iban = IBAN("DE89 3704 0044 0532 0130 00");

// For testing, the library will also generate random IBANs
const iban = IBAn.random(CountryCode.AT);
const iban = IBAN.random();
const iban = new Iban.Builder()
  .countryCode(CountryCode.AT)
  .bankCode("19043")
  .buildRandom();

// For simplicity in porting from iban-js applications
// you can quickly check validity
IBAN.isValid("AT611904300234573201"); // ===  true
IBAN.isValid("DE89 3704 0044 0532 0130 00"); // == true
IBAN.isValid("hello world"); // == false

Bic quick examples:

// How to create Bic object from String
const bic = BIC("DEUTDEFF");

// Check to see is BIC code is valid
BIC.isValid("DEUTDEFF500"); // === true

TODO

[ ] For random IBANs the National Check digits is random, rather than "valid" [ ] Finish writing all national check digit validators (see Oracle spec)
