Stage 1: ID Verification (The Structural Check)

ID Verification is the process of confirming that the South African ID number is structurally and mathematically sound. This relies only on the 13 digits themselves. Your ID Validator service primarily performs this, confirming Format Validity, Date of Birth Validity, Gender Digit Validity, and the Luhn Checksum Validity.

Stage 2: Identity Confirmation (The Data Match)

Identity Confirmation requires cross-referencing external, trusted data sources. This confirms that the structurally valid ID number belongs to the person providing it, checking for Name Match and Liveness/Existence. The Critical Takeaway for KYC: True KYC compliance requires both Verification (structural integrity) and Confirmation (person validation).
