# Contacts tab

On this tab, you can view a list of a client’s addresses and phone numbers as well as add the required contact information by clicking the **+Add** button.

## Addresses

In this section, the following information is provided:

**Address type**

The type of address:

* **Residential** — the client’s primary living address.
* **Billing** — the address associated with billing or invoices.
* **Mailing** — the address where correspondence is sent.
* **Birth place** — the location where the client was born.
* **Legal** — the official address used for legal purposes.

***

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.

***

**Confirmed**

* **Yes** — indicates that this phone number was the last one confirmed by the client via SMS.

  For example, if two phone numbers are provided and the client confirms the first one, it is marked as confirmed. If the client later confirms the second number, the second number becomes confirmed, and the first number is marked as unconfirmed.
* **No** — indicates that the phone number is unconfirmed.

***

**Default**

This field is deprecated and no longer in use.

***

![phone-button](/files/AMLzcbrdrltq1azckiqP) — the **phone** icon

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](/how-to-articles/manage-communication-platforms/how-to-configure-twilio.md)).

***

![delete\_button](/files/VyFoTPIADcJcBQBot8Ag) — the **bin** icon

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](/back-office-guide/system/settings.md#client-settings).
