Frequently asked questions
Does CheckID replace KYC?
No. CheckID performs structural validation and decodes the information in a South African ID number. It does not replace KYC, document checks, or other due-diligence steps.
Can our engineers use the API?
Yes. Solo + API supports single production calls. Professional and Business include REST API access, bulk validation, and team workflows.
Will raw ID numbers be stored?
No. ID numbers are processed in memory only and discarded immediately after validation. See the privacy policy for details.
Does this work for bulk processing?
Yes. Professional accounts can use bulk validation for high-volume customer onboarding.
