The Problem

Validating Israeli ID numbers, company registration numbers, and amuta (nonprofit) numbers is critical for any system that accepts customer data. The check digit is calculated using a unique algorithm, and validation failures can lead to registering fictitious customers, billing errors, or issues with government authorities. Despite this, many systems simply skip the validation entirely.
