# 'This phone number cannot be used for verification'

That message means the app refused the number before sending anything. It checked the number type or its history and said no.

## Why does the app say the number cannot be used for verification?

The app looked up the number and found it is in a range it does not trust: usually VoIP, a range used too often for sign-ups, or a country it limits. It never sent an SMS, so nothing is charged. Take a number from the physical-SIM pool, or from a different country, and try once.

## What triggers the message

- VoIP or virtual ranges: Google, WhatsApp, PayPal, Uber and banks run a carrier lookup and refuse non-mobile lines.
- Over-used ranges: a prefix that produced many accounts gets rate-limited for everyone.
- Country limits: some apps only accept numbers from certain countries, or from the country matching your IP.
- Account history: a number that already had an account on that app can be refused for a cooling period.

## What to do

- Use the physical-SIM pool for strict apps; the app pages list which ones need it.
- Match the country with your IP when the app checks location (most do for payments).
- Do not retry the same number; cancel and take another.
- If every country fails, the limit is on your device or IP, not the number.

## FAQ

**Was I charged?** No. Nothing was sent, so nothing is charged.

**Which countries pass Google?** Physical-SIM pools in the US, UK, Germany, Indonesia and the Philippines have the best recent rates; the Google page shows the live ranking.
