GET /v1/projects/{id}/platforms/sms/numbers/area-codes Lists current provider coverage for US local numbers, sorted and deduplicated. Coverage does not guarantee inventory carrying every required feature. New area-specific purchases must use a listed code; accepted purchases keep waiting if coverage later changes. Requires platforms:read for the path project.
