Google Expands Local Advertising Codes: What to Update

Listen to this article:

Google has expanded its list of local advertising codes. For most local service businesses, this sounds like a technical footnote that belongs to someone else. It is worth more attention than that. If you run Google Ads for a pest control company, an HVAC shop, a plumbing outfit, or a roofing crew, the codes Google uses to define places and local categories decide who sees your ads, where your budget goes, and whether your campaigns stay on the right side of advertising rules.

This article explains what these codes are and why an expansion matters to a business that serves customers in a defined area. It walks through how to audit your campaigns so you benefit from the change instead of being caught off guard by it. We will not guess at details we cannot confirm. Google publishes its own announcements and reference lists, and your account is the final word on what has changed for you. What we can offer is a practical way to think about the update and a checklist you can work through this week.

What Google's Local Advertising Codes Actually Are

When you tell Google Ads to show your ads in "Wake County" or "Cary, North Carolina" or a specific ZIP code, you are not typing free text that Google interprets on the fly. Behind every location you pick, Google uses a standardized identifier. These identifiers cover countries, states, counties, cities, postal codes, neighborhoods, airports, universities, congressional districts, and other defined areas. Google maintains a published list of these location codes, and advertising tools, reporting systems, and third-party software all rely on that list to stay consistent.

Local codes also show up in other places that affect a service business:

Location targeting and exclusions. Every place you include or exclude in a campaign maps to a code.
Location reports. When you look at where clicks and calls came from, Google groups that data using the same codes.
Local business categories. Programs built for local service providers use defined service categories and service areas to decide which searches a business can appear for.
Regional policy requirements. Some advertising rules apply only in certain countries, states, or regions, and Google uses location definitions to decide where those rules apply.

When Google expands this list, it can mean new locations become targetable, existing areas are defined more precisely, boundaries are updated to match real-world changes, or new categories become available. Any of these can change how a campaign behaves, even if you never touched the campaign yourself.

Why an Expansion Matters to a Local Service Business

A national retailer can tolerate a bit of fuzziness in location targeting. A local service business usually cannot. Your trucks go to specific towns. Your technicians have drive-time limits. Your licensing may cover some counties and not others. A click from a homeowner forty miles outside your service area is not just wasted money; it can turn into a phone call your office has to politely turn down, and that eats staff time too.

An expanded code list can help you in several ways:

More precise targeting. If a newly defined area matches your real service footprint better than the broad city or county you used before, you can target it directly and stop paying for clicks just outside your range.
Cleaner exclusions. New or refined areas can let you carve out neighborhoods, developments, or pockets you do not serve without cutting off the areas around them.
Better reporting. Finer location data in reports can show you which parts of your market actually produce calls, so you can shift budget toward them.
Compliance clarity. When regional requirements are tied to clearer location definitions, it becomes easier to know which rules apply to which campaigns.

An expansion can also create problems for accounts that nobody is watching closely:

Silent shifts in reach. If a boundary is redefined, a campaign targeting that area may start reaching slightly different households than it did last month.
Outdated targeting lists. Campaigns built years ago may rely on broad areas that now have better alternatives, leaving money on the table.
Broken spreadsheets and tools. If you or a vendor uploads targeting in bulk using codes, an outdated reference list can cause errors or mismatched locations.
Missed compliance steps. If a regional requirement now applies to an area you serve, the campaign may need updated information or verification to keep running smoothly.

None of this is cause for alarm. It is a reason to schedule a review instead of assuming last year's setup still fits.

How Campaign Targeting Drifts Out of Date

Many owners find that their Google Ads account looks reasonable on the surface but contains settings nobody has questioned in a long time. Location targeting is one of the most common examples. Here is how it usually happens.

The original setup was built for speed

When a campaign launches, someone picks a radius around the shop or a handful of cities and moves on to keywords and ad copy. That is a fair way to start. The trouble is that the first draft often becomes the permanent version.

The business changed but the campaign did not

You added a second location. You stopped serving a town because the drive was not worth it. You hired a technician who lives on the other side of the county, so now you can cover areas you used to skip. Each of these is a reason to revisit targeting, but in a busy season, updating ad settings rarely makes the to-do list.

Google's definitions changed

This is where the expanded code list comes in. Even if your business stayed exactly the same, the menu of places Google lets you target may have grown. A campaign built on the old menu may not take advantage of the new options.

The "presence or interest" setting was never checked

Google Ads lets you choose whether to show ads to people who are physically in your target area or also to people who have shown interest in it. For a service business that has to send a truck to a property, reaching people based on interest alone can waste budget. A homeowner researching a vacation rental in your town is not likely to book a termite inspection. This setting is easy to miss, and an update to location codes is a good moment to confirm it.

A Step-by-Step Audit for Your Google Ads Account

The following checklist works for most local service businesses. You can do it yourself if you are comfortable inside Google Ads, or hand it to whoever manages your account and ask for a written summary of what they found.

Write down your real service area first. Before you open Google Ads, list the towns, ZIP codes, or counties you actually want work from. Note any areas you will serve only for high-value jobs, such as a roof replacement but not a minor leak repair. This list is your reference point for everything else.
Export current location targeting for every campaign. Look at each campaign individually. It is common to find that different campaigns target different areas for no clear reason, usually because they were built at different times.
Compare targeting against your real service area. Mark any area that is targeted but not served, and any area that is served but not targeted. Both are problems: one wastes money and the other misses customers.
Search for more precise options. For each broad area you target, check whether Google now offers a narrower or better-matched location. Postal codes, neighborhoods, and smaller municipalities may be available where they were not before, or may be defined more accurately.
Review exclusions. Add exclusions for areas inside a broad target that you do not serve. Remove old exclusions that no longer apply, such as a town you now cover.
Confirm the presence setting. For most service businesses, targeting people who are in or regularly in your locations is the safer default. If you choose otherwise, have a clear reason.
Check location reports for the last several months. Look at where clicks, calls, and form fills actually came from. If a meaningful share of activity comes from outside your service area, your targeting or presence setting needs attention.
Review location bid adjustments. If your campaign uses bid strategies that allow location adjustments, consider whether certain areas deserve more or less budget based on job value, drive time, and close rate. If you use fully automated bidding, focus instead on giving the system clean targeting and accurate conversion data.
Update any bulk tools or spreadsheets. If you or a vendor manage targeting through uploads or third-party software, make sure the tool uses Google's current location reference list.
Document what you changed and when. Write a short note with the date and the changes. When you review results next month, you will want to know what caused any shift in performance.

This audit usually takes an experienced person an hour or two for a small account. For a larger account with many campaigns or multiple locations, budget more time. It is still a small investment compared with months of clicks from the wrong places.

The Compliance Side of Local Advertising Codes

The topic summary for this update mentions compliance alongside visibility, and that pairing makes sense. Location definitions are not only about reach. They also help determine which advertising rules apply to a given ad in a given place.

Regional rules apply by location

Advertising requirements can differ by country, state, or region. Some rules relate to disclosures, some to who may advertise certain services, and some to identity verification of the advertiser. When Google refines how it defines places, the boundaries of where those rules apply can become clearer. If your campaigns reach an area where a specific requirement applies, you may see prompts in your account asking for additional information or confirmation.

The practical step here is simple: do not ignore notifications in your Google Ads account. Many owners find that account warnings pile up because nobody logs in regularly except to pay the bill. A policy notice or verification request left unanswered can limit how your ads serve, sometimes without an obvious drop that you would notice right away.

Advertiser verification

Google asks many advertisers to verify their identity and business details. If your business name, address, or legal entity information in the account does not match what appears elsewhere, such as your Google Business Profile or state registration, verification can stall. An update to local codes is a reasonable prompt to confirm that your account information is current and consistent everywhere it appears.

Licensing and local service categories

Trades like pest control, HVAC, plumbing, electrical, and roofing are often licensed at the state level, and sometimes at the local level as well. Programs that place local service providers at the top of search results generally check licensing and insurance as part of their screening, and they organize businesses by service category and service area. If category or area definitions expand, it may open new job types or locations you can appear for. It may also mean you need to confirm that your licensing actually covers those additions before you turn them on.

A good rule: never advertise a service or area your license does not cover, even if the ad platform technically allows it. The platform's settings are not legal advice, and the consequences of advertising outside your license fall on you, not on Google.

Claims in your ad copy

Compliance also covers what your ads say. Statements about pricing, guarantees, response times, and certifications should be accurate and specific to the areas you target. If you offer same-day service in one town but not another, an ad that promises same-day service across your whole target area creates a problem. When you narrow or expand targeting, reread the ads that run in each area and make sure every promise holds up there.

Matching Targeting to How Local Customers Search

Codes and settings are tools. The goal is to put your business in front of the people who are likely to call, in the places you can serve well. A few principles help.

Radius targeting versus defined areas

A radius around your shop is easy to set up, but real service areas rarely look like circles. Rivers, highways, county lines, and traffic patterns shape where you can reach quickly. Defined areas such as ZIP codes or towns often match your real footprint better. An expanded code list can make defined-area targeting more practical because there are more precise building blocks to work with.

That said, very small target areas can limit how much data a campaign gathers, which can make automated bidding less effective. The right balance depends on your budget and market size. A company with a modest budget in a dense metro area may do best with a focused set of ZIP codes. A company serving a rural region may need broader areas to generate enough volume.

Separate campaigns for separate markets

If you serve two very different markets, for example a dense city and a spread-out rural county, consider separate campaigns. That lets you set budgets, bids, and ad messages that fit each market instead of averaging them together. Refined location codes make this kind of split cleaner.

Local relevance in ad copy and landing pages

Precise targeting works better when your message matches it. An ad that names the town the searcher is in, paired with a landing page that speaks to that area, tends to feel more relevant than a generic message. You do not need a separate page for every ZIP code, but grouping your service area into a few logical regions with tailored messaging is often worth the effort.

Audio branding can play a role here too. Many local service businesses use a short, memorable jingle across radio, video, and on-hold messaging so that people in their area recognize the name when they see it in search results. If that interests you, our jingles page explains how we approach it.

Your Google Business Profile still matters

Paid ads and your Google Business Profile work together. Make sure your profile's service area matches the areas you target in Google Ads. A mismatch can confuse customers and weaken the trust signals that help both your ads and your map listing perform.

Measuring Results After You Update

Changing targeting without measuring the effect is guesswork. Before you make changes, note your current numbers so you have something to compare against. Useful measures for a local service business include:

Calls and form submissions from ads, tracked as conversions in Google Ads.
Cost per lead, meaning total spend divided by real leads, not just clicks.
Share of leads from inside your service area, which you can estimate by reviewing call logs and form addresses.
Booked jobs and revenue, if you can connect leads to your scheduling or CRM system.

Give changes enough time to settle. Automated bidding systems often need a learning period after significant targeting changes, and a single slow week does not tell you much. Many owners find it helpful to compare a full month before and after, while keeping in mind seasonal swings. A plumbing company's December looks different from its May no matter what you change in the account.

If results get worse after a change, your documentation from the audit makes it easier to identify the cause and roll back a specific adjustment instead of guessing.

Watch conversion tracking closely

Targeting changes are only as useful as the data that judges them. If your call tracking is broken or your form conversions fire twice, you will draw the wrong conclusions. Before trusting any before-and-after comparison, place a test call and submit a test form, then confirm they appear correctly in your account.

Common Mistakes to Avoid

When owners or agencies respond to platform changes, a few mistakes come up again and again.

Changing everything at once. If you overhaul targeting, bidding, ad copy, and landing pages in the same week, you will not know which change helped or hurt. Stage your changes when you can.
Targeting too narrowly too soon. Cutting your area down to a handful of ZIP codes can starve a campaign of volume. Narrow gradually and watch the numbers.
Forgetting exclusions. Adding a new area without excluding the parts you do not serve can expand waste instead of reducing it.
Ignoring account notifications. Policy and verification messages exist for a reason. Read them and act on them.
Assuming the agency handled it. If someone else manages your account, ask directly whether they have reviewed targeting in light of the update. A good manager will welcome the question and give you a clear answer.
Advertising outside your license. Expanded options do not expand your legal authority to do the work. Check before you add new areas or service categories.

How Digital Marketing Raleigh Handles Updates Like This

Digital Marketing Raleigh is a done-for-you local marketing service operated by Petronella Technology Group, Inc. in Raleigh, North Carolina. We work with local service businesses that would rather spend their time running jobs than reading platform announcements. When Google changes something like its local advertising codes, our job is to figure out what it means for each client and make the right adjustments, not to send a newsletter and hope the owner handles it.

For a change like this one, our process looks much like the audit above. We start with the client's real service area and licensing, compare it against current targeting, look for better-matched location options, tighten exclusions, confirm presence settings, check policy and verification status, and document every change. Then we watch results over the following weeks and adjust based on real leads, not just clicks.

We also believe owners deserve clarity about what they are paying for. You can read how we stand behind our work on our guarantee page, and you can find more practical articles like this one on the Field Notes blog.

Frequently Asked Questions

Do I need to change anything right away?

Not necessarily. Existing campaigns generally keep running after Google updates its location codes. However, it is wise to review your targeting soon, because you may be missing better options or reaching areas you did not intend. Treat it as a scheduled task within the next few weeks rather than an emergency.

Where can I see what changed?

Google publishes announcements and reference materials for advertisers, and your Google Ads account may show notifications related to targeting or policy. The most reliable view of what matters for your business is your own account: search for locations you serve and see what options are now available.

Will this affect my Google Business Profile?

Your Google Business Profile is managed separately from Google Ads, but the two should agree. If you refine your ad targeting, check that your profile's service area reflects the same reality. Consistency across both helps customers and supports trust in your listing.

Is radius targeting still a good option?

Radius targeting can work, especially for a business with one central location and an even spread of customers. Many service businesses find that defined areas such as ZIP codes or towns match their real routes better. The expanded code list may make defined-area targeting more practical than it was before.

How does this relate to compliance?

Some advertising requirements apply only in certain regions, and Google uses location definitions to decide where they apply. Clearer definitions can mean clearer rules. Keep your advertiser information current, respond to any verification requests, and make sure you only advertise services and areas your licenses cover.

My agency manages my ads. What should I ask them?

Ask whether they have reviewed your location targeting since the update, whether your presence setting targets people physically in your area, whether exclusions match the areas you do not serve, and whether any policy or verification notices are pending. Ask for a short written summary of what they checked and changed.

Can a narrower target area hurt my results?

It can if you narrow too far. Very small target areas may not generate enough searches for a campaign to perform well, especially with automated bidding. Narrow in stages, watch lead volume and cost per lead, and widen again if volume drops too much.

How long should I wait before judging the results of a change?

Give significant targeting changes several weeks at minimum, and compare similar time periods where possible. Seasonal demand in pest control, HVAC, plumbing, and roofing can swing a lot, so a fair comparison accounts for the time of year.
