The type of address:

Details of the address, such as **Country**, **City**, **State**, **Postal code**, and street address.

## Phones

In this section, the following information is provided:

**Phone**

The client's phone number provided during registration (if your registration procedure requires phone numbers) or added by a Back Office user.

The option to dial the specified client's phone number from the Back Office.

To use this option, a phone service provider, such as Twilio, must be configured (for details, refer to [How to configure Twilio](https://docs.b2core.b2broker.com/how-to-articles/manage-communication-platforms/how-to-configure-twilio)).

This option is available if you're granted the `Update clients` permission, which includes the ability to edit client information on the **Contacts** tab. By clicking the icon, you can delete any added phone numbers, including the confirmed phone number.

After removing a confirmed phone number, a client can add and confirm a new phone number to associate with their profile.

Once removed, the phone number becomes available for registering a new client profile, assuming that your registration procedure requires [phone numbers to be unique](https://docs.b2core.b2broker.com/system/settings#client-settings).
