Service area

A service area is the set of towns, counties or ZIP codes a company will send a truck to. For a plumber, electrician or HVAC shop it does two jobs: it decides which calls get an appointment, and it is what Google shows customers when the business has no storefront they visit.

What a service area ZIP code is

A service ZIP code is simply a ZIP code on that list. When a caller gives an address, whoever answers checks the ZIP against the list: inside, the call is booked; outside, the caller hears that the shop doesn’t cover that area and is offered a message instead. Shops often list ZIP codes rather than town names because a town line and a ZIP boundary rarely match, and every address already carries its ZIP.

Service area on a Google Business Profile

Google calls a company that visits or delivers to customers, and doesn’t serve them at its own address, a service-area business, and gives plumbers as an example. Its rules, from Google Business Profile Help:

• If you don’t serve customers at your business address, remove the address from the profile and set a service area instead.
• You can set up to 20 service areas, by city, postal code or another type of area.
• The boundaries of your overall area shouldn’t be more than about 2 hours of driving time from where the business is based.
• A service-area business can have only one profile for the whole area it serves.

Keep the list on your profile and the list your phone team works from the same, so a caller who found you on the map isn’t turned away on the phone.

Why it matters for a service company

A booked job forty minutes past your usual edge is not a win. The tech spends most of an afternoon slot driving, the fuel and the hour come out of the ticket, and the two calls that came in from your own town while the truck was gone get tomorrow. That is the arithmetic: if the ticket is $89 and the round trip costs an hour of a tech’s day, you paid to do the job.

The boundary also moves. You take a job across the county in February because the board is empty, then get called back to the same house in July when every truck is spoken for. A heat wave or a first freeze fills the board fast, and the edge of the map is the first thing an owner tightens.

Then there is the caller who wants you anyway. A landlord with three units on the far side of the line, a repeat customer who moved. A hard no on the phone loses them; a message the office can review keeps the decision with you.

How DispatchLine handles it

In DispatchLine the service area is one of the business facts you set in the portal. The agent asks every caller for the address, books callers inside the area into an arrival window, and offers callers outside it a message instead of an appointment.
