# Deactivate a brand/campaign registration

`DELETE /v1/sms/registrations/{id}`

Terminates the campaign with the carrier registry so the recurring
monthly campaign fee stops (carriers bill the first 3 months of a
campaign regardless). Numbers covered by it can no longer SEND texts —
receiving is unaffected — until they're registered under a new brand.
Irreversible: a deactivated campaign cannot be restored; texting again
later requires a new registration (new one-time and review fees).
Idempotent.
