Discord says this phone number is already in use
Quick answer
Discord links a phone number to one account. If it's already in use, you may have an older Discord account on it, or the number was recycled from someone else. Log in to the old account and remove the number, or use another number. With a Noir SMS number, cancel and try another one; Discord also rejects many VoIP numbers outright.
This shows up when you verify a phone in Discord's settings or for a server. Here's how to deal with it.
If it's your old account
Log in to the old account, go to User Settings, My Account, and remove the phone number. Then add it to your new account.
If it's not yours
You can't unlink a number from another account. Use a different number.
VoIP and invalid numbers
Discord rejects many VoIP numbers with a message that the number is invalid. Noir SMS numbers are mobile numbers from carriers, which Discord usually accepts.
