WhatsApp Phone Numbers

Pre-validate KYC address

Deprecated alias of /v1/phone-numbers/kyc/validate-address; same contract. New integrations should use that path.

Optional early check for the address step of a Tier 4 (end-user identity) registration: validates a postal address for deliverability BEFORE the full KYC submit, so it can be corrected before any documents are uploaded. The full submit (POST /v1/whatsapp/phone-numbers/kyc) re-validates the address, so this call is purely a fast feedback path and skipping it is safe. Only the postal address is sent (no documents, no gov-ID fields). A region (administrative_area) is required by the validator; when it is omitted the pre-check is skipped and { ok: true, skipped: true } is returned (the final submit still validates).
