ZIP Code Strategy: How to Choose Your Service Areas

01Why the ZIP code matters as much as your advertising

A locksmith is a hyper-local service: a customer almost always picks whoever is closer and arrives faster, not whoever has the nicer website. Because of that, a customer's ZIP code is more than a line in an address field: it's one of the factors driving a job's profitability. Drive time between calls costs more than gas and wear on the vehicle. While a tech spends forty minutes driving across town, he physically can't take a closer call — and that's a lost job.

At the same time, different neighborhoods rarely bring the same profit. Some ZIPs have a higher average ticket, often thanks to commercial properties and jobs involving parts, while others are mostly one-off lockouts at the minimum rate. Demand density and locksmith ad competition also vary from area to area, and that affects how much actually ends up left over after ad spend and drive time.

02How to analyze jobs by ZIP

If you already have some job history, the most honest way to figure out which areas are worth it is to look at the actual numbers instead of relying on a gut feeling that "this neighborhood seems decent." Grouping completed jobs by customer ZIP shows where the average ticket is higher, where repeat customers and commercial contracts show up more often, and where one-off lockouts at the minimum price dominate.

It's also worth looking not just at revenue per job, but at how much time and ad budget it took to land that job. A ZIP with a modest average ticket but short drive time and cheap ads is sometimes more profitable than a distant area with big jobs but expensive ads and a long drive.

03Ad geotargeting: radius or ZIP

In Google Ads and Local Services Ads, geotargeting is usually set up one of two ways: a radius around a specific point — an office, a parts warehouse, a tech's home — or a list of specific ZIP codes. Both options generally work better than targeting an entire city or county at once: a budget spread thin over a huge territory more often gets burned on clicks from areas it isn't worth physically driving to.

Specific ZIPs are handy because you can fine-tune the zone precisely: drop one ZIP with a low average ticket, add a neighboring one with a higher ticket, without touching the rest of the campaign setup. A radius is simpler to start with, but it accounts less for the fact that neighboring ZIPs can differ a lot in profitability, even when they're geographically close.

04Expand your radius or concentrate

Expanding your ad radius almost always increases reach — and almost always increases competition and average drive time at the same time. More locksmiths compete for the same leads, and some of the new jobs end up physically far from your current service area, which eats into part of the gain from the increase in leads.

Concentrating on a handful of ZIPs works the other way: fewer competitors, especially if you manage to establish yourself as the local specialist in a specific neighborhood, but the available demand is also capped by that territory's ceiling. In practice, many locksmiths combine both approaches — keeping a core of a couple of proven ZIPs and cautiously testing neighboring areas with a small budget.

05Signs of an unprofitable ZIP

A few signs usually indicate that expanding into a specific ZIP isn't worth it yet. The first is a long drive to that zone with no other jobs along the way: if you have to drive there specifically instead of "on the way," a single job there costs more than it looks like on the ticket. The second is a consistently low average ticket compared to areas you've already established.

• Long drive with no jobs along the way — drive time doesn't pay for itself given the volume of leads from that zone.
• Low average ticket — compared to ZIPs you've already established.
• High saturation of competitor ads — which, as a result, means an expensive CPC before the tech even rolls out.

If at least two of these signs line up, it's smarter to test the zone with a small ad budget first rather than committing to a full-scale expansion right away.

06How to tell which areas pay off

It's fairly hard to eyeball which areas actually pay off and which only look promising — there might be plenty of leads but little actual profit. If your ads and jobs are tagged by source and tied to the customer's address, a breakdown by ZIP turns from a guess into a checkable number: average ticket, share of repeat customers, and the ratio of leads to completed jobs for each zone.
