Exclusivity is not automatic
A number may be exclusive for an order, shared, or later recycled. The offer must state its privacy model instead of leaving users to assume.
Message retention
The interface should explain how long received messages remain visible, who can access them, and when they are deleted.
Protect future access
Do not place sensitive personal, financial, identity, or recovery flows on a temporary number. Prefer app-based authentication or a durable number you control for long-term security.
