# Phone Number Setup

> Reserve your AI Receptionist's phone number.

Your AI Receptionist needs a dedicated phone number that callers can dial. hyzl provisions this number for you. Each receptionist gets its own dedicated number. If you run [multiple receptionists](/docs/ai-receptionist/managing-receptionists), hyzl provisions a number for each one.

## Reserve a number

During the receptionist setup wizard:

1. Go to the **Number** step
2. Enter an area code (e.g. `415` for San Francisco)
3. Click **Search**
4. Choose a number from the list
5. Click **Next**
6. Finish the wizard
7. Click **Launch AI Receptionist Agent** on the Review step

hyzl reserves the number at that last click. It then assigns the number to your account, ready to receive calls.

## Use the number

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

## Multiple numbers

Each receptionist has its own dedicated number, and you can run more than one receptionist. hyzl provisions every added receptionist with its own number and bills you accordingly. There is no cap. See [Manage multiple receptionists](/docs/ai-receptionist/managing-receptionists).

## Limits

* **No porting.** You cannot bring an existing business phone number into hyzl. The numbers you reserve here are the only ones your receptionists can use.
* **hyzl-provisioned only.** Numbers must be reserved through the portal. You cannot connect a number from another carrier.

If you need to use an existing external number, forward it to your hyzl number using your carrier's call-forwarding feature.
