ZA ID Validation


ID Validations is a web service that uses an algorithm the ID number of an employee, debtor or creditor. Any software that allows for the capture of bank account details should implement this web service as it is critical for the success of other Netcash services requiring bank details such as ID number, verification, bank codes or payments. This service does NOT verify (See ID Verification) that the ID number is active or belong to the employee, debtor or creditor.

This service is to be used on input of data into the application to ensure that the Banking details supplied are valid. It is recommended that Universal Branch Code processing is used for the validation to be effective
