Start with the question you need to answer: how to receive a code, how long to keep a number, how to order, or why a message did not arrive.

 

## Choose how to receive a code

These resources separate a shared public inbox, a private short order, a rental and your own mobile line. The right model depends on message visibility and whether a later sign-in needs the same number.

## Resolve a failed or finished order

Read the sender’s screen and the number order together. A missing message, a rejected number and an expired order call for different next steps.
