A release call in the owning account that deletes the incoming number and, best-effort, its Messaging Service. It is only safe before an A2P campaign is attached, which the route layer guards.
Also called: release number · wrong number · cancel the number · stop the monthly charge
- 1Operator or admin releases a number that has no campaign attached.
- 2The number is deleted in the account that owns it; a 404 is treated as already released.
- 3The Messaging Service is deleted best-effort — an orphaned empty service costs nothing.
- 4The monthly charge stops immediately.
Documented directly on the function: 'the "actually, I want a different number" path. Only safe BEFORE an A2P campaign is attached (the route layer guards that). Stops the number's monthly charge immediately.'
- A mistakenly purchased number kept billing with no way to hand it back.
- Releasing a number attached to a campaign would break compliance.
