# Check DNC status for a phone number

> Returns whether the given E.164 phone number appears on any of the platform's Do-Not-Call sources (tenant contacts.dnc, tenant dnc_list, platform-wide DNC, explicit consent opt-out). Read-only — does not perform a send. Use this before any outbound SMS / Voice initiation to pre-flight the compliance check that the actual send path enforces.

**Gated behind `organizations.settings.dnc_sync_enabled` (audit #SCAN-CMP-005).** Federal/state/TCR feed ingestion is currently a stub; tenants must explicitly opt in (acknowledging the gap) before the endpoint is served. When the flag is OFF, responses are HTTP 403 with code `DNC_SYNC_NOT_ENABLED`. When ON, responses include `federal_feeds_synced: false` until real FTC/state/TCR sync lands.
