Free App Verification Numbers to Receive SMS Codes

This is the index of SMS verification numbers by app. Every app below has its own page carrying the numbers that have actually received a message from it, how that app verifies, and a straight answer about whether a public number is likely to work. If you want app verification numbers but do not much mind which app you start with, read the table under the list — it sorts them by odds rather than by popularity.

Apps differ on this more than countries do, and the gap between the best and the worst is wide. The table summarises what the twelve pages explain in full:

The rule behind the table: the more an app treats your number as the permanent identity of the account, the harder it screens public lines. An app that asks once at signup is relaxed about it. An app that makes the number the key to account recovery is not — and there a public number is a risk to you before it is a problem for them.

1. Start with the app, not the country. The app is what accepts or refuses the number. The country only matters when the service itself is geo-restricted.
2. Pick a line that received something recently. It is the clearest evidence the line is still live; one that has been silent for days may have stopped.
3. Read the failure mode before you try. Every app in the middle and bottom rows above has a known reason it rejects public numbers, and reading it saves you ten attempts.
4. Do not build a permanent account on a public number. The inbox is open to every visitor, and whoever reads your code can recover your account.

If you want a specific country for a specific app — a US number for WhatsApp, say — each of those pairs has its own page, linked from the app page itself.
