The Problem

Guessing Your Service Area Leaves Money on the Map

Most businesses describe their area as about 25 miles, then list towns from memory.

Memory misses towns
Smaller places inside your radius often never make it onto your profile or website.
Pick a center, set a radius
Type a ZIP or a city, or click the map, then slide the radius from 5 to 100 miles.
Get the full list
Every ZIP and city in the circle, sorted by distance, ready to copy or export.

Under the Hood

How the Radius Math Works

Distances are straight line miles from your center to the center point of each ZIP.

Haversine distance

The formula measures distance over the curve of the earth, not a flat map.

ZIP center points

Each ZIP is one point. A ZIP whose edge crosses your circle but whose center does not is left out.

City lookup

A city search uses the average center of that city's ZIPs. Without a state, the largest match wins.

ZIP and population data come from GeoNames, shared under the CC BY 4.0 license.

Radius vs Areas

Radius vs Named Service Areas in Google Business Profile

Business Profile service areas are named places like cities or ZIPs, not a drawn radius.

Named areas

What Google asks for.

Up to 20 cities, ZIPs or regions
Shown on your profile
Easy to match on your website
Needs you to choose which places

A rough radius

What most owners think in.

Simple to describe to staff
Good for planning routes
Not something you can enter in your profile
Hides which towns you skip

Google suggests keeping service areas within about two hours of driving from where your business is based.

Suggestions

How the 20 Suggested Service Areas Are Picked

The tool ranks cities by population when it has the number, and by distance when it does not.

Rule	What happens
Population known	Largest cities first, using whole city population from GeoNames
Population missing	Smaller places with no number on file come after, closest first
No population at all	The list falls back to the 20 closest cities
Cap	Never more than 20, the Business Profile limit

Population known

What happens: Largest cities first, using whole city population from GeoNames

Population missing

Cap

Choosing Well

How to Choose Your Service Areas

The suggestion is a starting point, so trim it to the places you really want work from.

Places you serve today

Only list towns where you take jobs now.

Reasonable drive times

Straight line miles can hide a long drive around mountains or water.

Where the jobs are

Check your past invoices for the towns that bring the most work.

Where you have proof

Towns with reviews and job photos make stronger city pages later.

Next Step

From ZIP List to Service Area Pages

Once you know your cities, turn them into a page plan with no retyping.

Find your cities
Run the radius search and review the suggested list.
Send to the planner
One click opens the service area page planner with up to 20 cities filled in.
Plan the pages
Get slugs, titles, priorities and a link map for each city.

Need the same area as a map file? The KML generator draws a radius circle you can import into Google My Maps.

Why It Matters

What a Vague Service Area Costs You

If you do not name the places you serve, customers and search engines have to guess.

Customers bounce

Someone in a small town sees no mention of it and calls a competitor who lists it.

Wasted slots

Twenty profile service areas filled with overlapping names, while real towns go missing.

No ranking promise

Service areas do not decide rankings on their own. They make your coverage clear.

Fix Guide

ZIP Radius Problems and Fixes

Odd results usually come from how ZIP codes work, not from the math.

The city search picked the wrong state

Add the state code, like Springfield, IL.

A ZIP you serve is missing

Its center sits outside the circle. Raise the radius a little or add it by hand.

A ZIP is not found

PO box and military ZIPs may not be in the data. Use a nearby ZIP as the center.

Population shows n/a

Smaller places may have no number on file. They still appear in the results.

FAQ

ZIP Radius Finder FAQ

10 answers about limits, results and how the tool works.

How do I find all ZIP codes within a radius?

Type a ZIP code or a city and state, or click the map, then set a radius between 5 and 100 miles. The tool lists every ZIP whose center point sits inside that circle, sorted by distance. You can copy the ZIPs, export them as a CSV, or group them by city.

Is this ZIP radius finder free?

Yes. There is no signup and no limit on searches or exports. The ZIP list loads once as a file, and all the distance math runs in your browser. Nothing you type is sent to our server. You can run as many radius searches as you need for yourself or your clients.

Are the distances driving miles?

No. They are straight line miles from your center to the center point of each ZIP, measured over the curve of the earth. Driving distance is usually longer, especially around mountains, lakes or rivers. Treat the radius as a planning guide, then trim towns with long drives.

How many service areas can I add to Google Business Profile?

Google lets you add up to 20 service areas. They can be cities, ZIP codes or other named regions. Google also suggests keeping them within about two hours of driving from your base. That is why this tool suggests no more than 20 cities from your radius.

Should I add ZIP codes or cities as service areas?

Most businesses use cities, because customers recognize town names and 20 slots go further. ZIP codes can make sense in dense metros where one city is too large to serve fully. Whichever you choose, use the same places on your website so your profile and pages agree.

How are the suggested cities chosen?

Cities with a known population from GeoNames are ranked largest first. Smaller places with no number on file come after, closest first. The list stops at 20. It is a starting point, so remove towns you do not serve and add any you work in often.

Does it work outside the United States?

Yes. Pick your country first. The US uses a built in list of more than 40,000 ZIP codes. For 44 other countries, including the UK, Canada, Australia, India and Pakistan, the tool finds postcodes and towns in your radius from OpenStreetMap, in miles or kilometers.

Why is a ZIP I serve missing from the results?

Each ZIP is stored as one center point, not a boundary. If part of the ZIP sits inside your circle but its center sits outside, it is left out. Raise the radius by a mile or two, or simply add that ZIP to your list by hand.

Can I export the ZIP codes to Excel?

Yes. Export the ZIP CSV for one row per ZIP with city, state, distance and coordinates. Export the city CSV for one row per city with its ZIPs and population. Both open in Excel, Google Sheets and Numbers. You can also copy the plain ZIP list with one click.

Do service areas help my local rankings?

Google has not said that service areas are a ranking factor, and we will not claim they are. They tell customers where you work and appear on your profile. Clear service areas, matching city pages and real local reviews work together to show your coverage honestly.

Turn Your Radius Into 20 Real Cities

Draw the circle you really drive, copy the cities into your profile, and plan the pages that back them up.
