npm install @adia-technology/international-ssn-validator --save

import { validateSsn, ValidationResult } from '@adia-technology/international-ssn-validator';

let validationResult = validateSsn('756.1111.2222.00', 'ch');
let isValid = validationResult === ValidationResult.Valid;

This library exposes a single function, validateSsn, that accepts two parameters:

• ssn : string - SSN to validate.
• countryCode : string - country for which to check the SSN against. Currently supported are us and ch.

It returns a ValidationResult, which essentially is a string enum being set to one of the values: 'VALID', 'INVALID_FORMAT' or 'INVALID_CHECKSUM'.

This library uses the following other libraries:

• ahv13-validator (ISC License)
• ssn-validator (MIT Lincense)
