# Save (or update) the Display Identity Record draft

> Persists the brand display name + call reason against the caller's enterprise. Saved as DRAFT until `POST /v1/caller-trust/brand/submit` flips it to PENDING_SUBMIT (which is then batch-pushed to the carrier by a nightly worker once Branded Calling launches).
