Guides to SMS verification

How virtual numbers work, and where they fall down.

What do these guides cover?

Four questions people actually hit: how to receive a code without giving up your own number, why a code sometimes never arrives, how to pay without the payment identifying you, and what actually gets an account flagged. Each is written to be useful whether or not you buy anything here.

Where should you start?

If you have never used a virtual number, start with receiving a code without a phone number. If you have one and it is not working, start with the guide on codes that never arrive — most failures happen before a message is ever sent, and it explains how to tell which case you are in.
