Notes on virtual numbers
How the numbers work, why codes go missing, and what the catalogue figures actually mean. Written by the people who run the rail.
X (Twitter) verification without your own number
X takes an email at sign-up and comes back for a number later, usually once it has locked the account. Which prompt is which, and what to do after.

Facebook will take an email at sign-up and ask for a number later — and there the number is also a way back in. Which prompt is which, and what to switch off.
Self-hosting an AI model: the accounts that still ask for a phone number
Open weights download in a single command and a GPU rents by the second — the compute stopped being the hard part. The friction is everything around it: the bot platform, the registry, the hub, each stopping to ask for a phone number at the worst possible moment. Which ones genuinely require one, and where a one-time code is the right answer.

TikTok takes an email at sign-up and wants a number later — for LIVE, for Shop, for a login it distrusts. Which prompt is which, and why the country sticks.
Instagram verification without your own number

Google asks for a phone number on most new accounts and is stricter than almost anything else about which ones it takes. What works, what does not, and the mistake that costs people the account later.
Non-VoIP numbers: why services reject VoIP
Platforms do not guess. They look your number up in the carrier databases before they send anything, and the line type they get back decides it. Here is what that lookup sees.
Free SMS numbers: what they actually do, and where they stop
Public inboxes are genuinely useful for some things and hopeless for others. Here is the line between the two, and how to tell which side your sign-up falls on before you waste an evening.
Where to start
Three ways in, depending on what you came for.
- How it works What a virtual number is, how a code actually travels, what it costs and whether any of it is legal. Start here if you have not bought one before.
- Guides Step by step, service by service — which country to pick, in what order to do things, and what to set up before the number goes back to the network.
- Troubleshooting The code did not arrive, the service refused the number, the account is asking again. What each symptom means and what actually fixes it.
