# Phone Number Setup

> Reserve your AI Receptionist's phone number.

Your AI Receptionist needs a dedicated phone number that callers can dial. Atllas provisions this number for you — every account gets exactly one number, purchased through Atllas.

## Reserving a Number

During the receptionist setup wizard:

1. Navigate to the **Phone Number** step
2. Search for available numbers by area code (e.g. enter `415` for San Francisco)
3. Select a number from the list
4. Click **Reserve Number**

The number is immediately assigned to your account and ready to receive calls.

## Using the Number

Once reserved, share this number as your business phone number — on your website, Google Business Profile, email signatures, and marketing materials. All calls to this number are handled by your AI Receptionist.

## Limits

* **One number per account.** Multiple-number setups are not supported.
* **No porting.** You can't bring an existing business phone number into Atllas. The number you reserve here is the only one your receptionist can use.
* **Atllas-provisioned only.** Numbers must be reserved through the portal. You can't connect a number from another carrier.

If you outgrow these limits, your alternative is to forward an external number to your Atllas number using your carrier's call-forwarding feature.
