If you have a multi-currency account, you have the option to send and receive money from other people who have one, using just a phone number. This is because we match the phone number registered in your account with the one that’s in their phone’s contacts.
This feature is automatically switched off, so if you don't want people finding you using your phone number, you don't have to do anything.
This is how to switch the feature on and off in your account.
On the app:
When it's off, you also won’t be able to send money using your own phone’s contacts.
We never send or store your full phone’s contacts on our servers. We also never get in touch with your contacts. We only use this information to make it easier to send money between you and your friends.
Bear in mind that when you switch the feature on, any TransferWise customer with your phone number will see your account name and photo on their TransferWise app.
