# Set up zones and assign technicians to them

> Create service-area zones in ServiceTitan and put technicians in them so Avoca only offers times in the areas each technician covers.

A zone is a service area in ServiceTitan, made up of ZIP codes. Zones tell ServiceTitan which technicians cover which parts of town. Skip this guide if all of your technicians cover your whole service area. In ServiceTitan, find zones under **Settings → Operations → Zones**.

## Create a zone

**1. Open Zones**

In ServiceTitan, go to **Settings → Operations → Zones** and select **Add**.

**2. Name it and add ZIP codes**

Name the zone and add the ZIP codes it covers. To add a whole range at once, use a wildcard, like `912*` for every ZIP code that starts with 912.

**3. Choose its business units**

Pick the business units that work in this zone. If you don't see this field, ask your ServiceTitan contact to turn on business unit filtering by ZIP code.

**4. Save**

Repeat for each area you serve.

## Assign technicians to zones

**1. Open the technician**

In ServiceTitan, open **Settings**, then **Employees & Technicians**, and select the technician.

**2. Choose their zones**

In the **Zones** field, pick the zone they work in. Add more if they cover several.

**3. Save**

Repeat for each technician who works in a specific area.

A technician with a zone only takes jobs in that zone. A technician with no zone takes jobs in every zone.

> [!WARNING]
>
> If you use zones in Adaptive Capacity, check that the setting that includes zones in availability is on. If you turn it off, zones stop limiting who can take a job. Make sure every zone that has ZIP codes also has technicians and business units, or customers in that area may get no times.

## Test it

**1. Pick a ZIP code in one zone**

Choose a ZIP code covered by a zone, and a technician assigned to that zone.

**2. Open Call Booking**

In ServiceTitan, enter a customer address in that ZIP code. You should see times from that technician.

**3. Try a ZIP code in another zone**

The technician's times should not show there.

## More options

> [accordion] What does Avoca check?
>
> If you assign technicians by zone, Avoca checks that each zone with ZIP codes has at least one technician and one business unit. This check is optional, so a gap shows as a warning and doesn't block setup.

> [accordion] How do zones relate to my Avoca service areas?
>
> Your Avoca service areas decide which callers your assistant will book. You can import your ServiceTitan zones into them. See [Catalog and service areas](https://help.avoca.ai/business-info/catalog-and-service-areas.md).

> [accordion] I want a technician left out of regular booking
>
> One way is to put them in a zone outside your normal service area. This only works when zones are included in availability.

> [accordion] Zones differ by business unit
>
> Zones are tied to business units in ServiceTitan. If you run several business units, set up each one's zones separately.
