Check the signing Owner's PAN against the confirmed company's directors

The Owner enters their own PAN and the name on it; the register provider checks it against the directors and signatories of the registration confirmed by POST /v1/activation/business-registration:confirm. DIRECTOR_MATCH completes rail step business_verification (no hosted KYB session needed); NOT_A_DIRECTOR is a 200 result, not an error: the step reads needs_you (needs[] signatory.pan) and the hosted KYB session (POST /v1/activation/verification-sessions) stays the fallback. result is x-extensible-enum. Before a registration is confirmed the check is 409 CONFLICT details.reason REGISTRATION_NOT_CONFIRMED. The PAN is sent to the provider and never stored or echoed: the answer carries panLast4 only. A PAN that does not match the pattern is 400 VALIDATION details.field pan. The check is for the signed-in Owner only: when the Owner's name is known (AccessContext.givenName and familyName), nameOnPan must equal givenName + " " + familyName compared without regard to case or whitespace, else 400 VALIDATION details.reason SIGNATORY_NOT_SIGNED_IN_USER and nothing is sent to the provider. At most 5 checks per tenant per UTC day (replays of an Idempotency-Key do not count): the sixth is 429 RATE_LIMITED details.reason SIGNATORY_ATTEMPTS_EXCEEDED with Retry-After (seconds to the next 00:00 UTC) and details.retryAfterMs; step business_verification then reads needs_you (needs[] kyb.hosted) and the hosted KYB session is the path. Human session only; Owner only. Idempotency-Key required. Audited (activation.signatory_checked, with the result and panLast4). method picks the check. PAN (the default when method is absent) is the check above and needs pan and nameOnPan (India). NAME_DOB needs dateOfBirth only: the signed-in Owner's name (AccessContext.givenName and familyName) and date of birth are checked against the directors, officers, members or managers the register names for the registration confirmed by scheme and number (GB, AE, US, CA). DIRECTOR_MATCH (GB, AE, CA) or OFFICER_MATCH (US, an officer or member named on the register) completes the signatory part of business_verification; NOT_A_DIRECTOR leaves it needs_you with hosted KYB the fallback. Exactly one method's fields: pan or nameOnPan with NAME_DOB, or dateOfBirth with PAN, is 400 VALIDATION details.field naming it, and a missing field of the method is 400 VALIDATION details.field naming it; NAME_DOB on an India registration is 400 VALIDATION details.field method (India checks by PAN). Either method needs a confirmed registration first (409 REGISTRATION_NOT_CONFIRMED, above). The date of birth is sent to the provider and not kept by this route (the business-people record holds the representative's). result also takes OFFICER_MATCH (x-extensible-enum); panLast4 is absent on NAME_DOB and method echoes the check made. The attempt limit above counts both methods.Headers
