We do not recognise that number
We do not recognise that number: what the ForestVPN message cp.account_unknown means, why it appears and what to do about it.
Updated October 11, 2026
The app says: "We don't recognise that number. Check it and try again."
What it means
No account has the number you typed.
What to do
Check the number for typing mistakes. If you changed your number, the old one stops working everywhere. See lost your number.
Why it happens
The number has a typo, belongs to a deleted account, or has been changed.
Where you see it
The ForestVPN apps show this message where the step failed: on the Account, Devices or link screens, and on the console at fvpn.net. The code is cp.account_unknown.
