Should You Target One County or a Broader Radius When Hiring Certified Plumbers?
The right geographic scope depends on how many licensed plumbers live within a realistic commute of your job site and whether you are filling one role or building ongoing capacity. A metropolitan area with a deep pool can often be worked one county at a time. A rural county with a small pool usually needs a wider radius. This article is for contractors, service companies, and hiring managers weighing that choice before they commit to a direct mail audience.
- Start with one county if your job site is central, the local licensed pool is large, and you are hiring for a fixed location.
- Widen the radius if the county pool is small, your site sits near a border, or you are hiring for several roles.
- Commute reality beats county lines. Counties are administrative boundaries, and candidates think in drive time.
- Response tracking works at any scope. QR scans and landing-page traffic show you what each geography produced.
A note on fit: RecruitCard's deepest expertise is licensed healthcare hiring. The same model, targeting by license type or trade and by geography, extends to skilled-trade employers reaching licensed or certified candidates, including plumbers. The geographic trade-offs below apply to both.
Why does geographic precision matter for licensed plumber recruiting?
Precision matters because the plumbers you most want are usually already employed, and a mail piece only helps if it reaches someone who can realistically report to your site.
Mail reaches people who are not searching
Job boards and paid search only reach people who are actively looking. A working journeyman or master plumber who is reasonably happy where they are will rarely browse postings. A personalized card that arrives at home reaches that person with far less competing noise than a listing on a crowded page.
Location filters out wasted mail
Targeting by county, city, or radius keeps your audience to people within reach of your coverage area. Mail sent to candidates too far away to commute is mail that cannot produce a hire. A tighter geography keeps the audience relevant to your actual service area.
License type and location work together
Plumbing licensure is generally set at the state or local level, so the license and the location are linked. Targeting by license type and geography together means your card goes to people in the trade, not to generic professionals who happen to live nearby. It also lets you write the message in the language of the work.
When should you choose a single county or local radius?
Choose a single county when the local licensed pool is large enough to generate meaningful response and most of that pool can reach your job site without an unreasonable commute.
Your site is central and the role is permanent
A fixed location with a permanent opening is the classic single-county case. If the county is compact, or your shop sits near its center, most licensed plumbers in the county are plausible candidates. Your card can say you are a local employer, and that message carries weight with tradespeople who value a short drive.
A tighter radius keeps mail volume focused
A smaller audience means less mail to produce and send. It also concentrates your message on people who see you as part of their own community. For many employers that is a sensible first step.
Ongoing campaigns give you room to test
If you hire continuously, a single-county campaign is a clean baseline. You can see what the response looks like, adjust the message or the geography, and run it again. You are learning from real response data instead of guessing.
When should you expand beyond one county?
Expand when your home county does not hold enough licensed plumbers to produce a response you can learn from, or when commuting patterns cross county lines.
Small pools need a wider net
If the number of licensed plumbers in your county is small, even a well-written card may reach too few people to close the role. Adding neighboring counties, or moving to a multi-county radius, gives the campaign enough reach to be worth running.
Rural and specialized roles often need distance
Rural areas and smaller metro regions tend to have thinner local pools. Specialized roles, such as industrial or commercial service plumbing, narrow the pool further. In these cases a broader radius is often the only way to build an audience large enough to work.
Border sites share a labor market
If your shop is close to a county line, candidates on the other side may have a shorter drive than people in the far corner of your own county. Drawing the boundary at the county line would exclude people who are practically your neighbors.
Multiple openings or a pipeline call for steadier reach
If you are hiring for several roles, or you want a pipeline ready before the next vacancy, a larger geographic net keeps mail going out over time without exhausting a small audience too quickly.
How do you build the right audience for your specific hire?
Build it from three facts: the size of the local pool, the realistic commute to your site, and whether you are filling one role or hiring continuously.
Check the size of the pool
Before you choose a boundary, find out roughly how many licensed plumbers sit inside it. If the count is very small, a single-county campaign may not generate enough response to tell you anything. We can talk through audience size and scope when you plan a campaign.
Anchor on commute, not the map
Think about how far plumbers in your market will actually drive for a job. In a dense metro, that may be a short distance. In a rural area, people often travel much farther. Let that reality shape the boundary instead of the county line.
Match scope to the hiring need
One critical opening in a hard-to-reach market may justify a wide audience for a single push. Ongoing hiring in a deep market can run on a tighter audience, repeated over time.
Write the card for the geography
The card itself should reflect your scope. A good mail piece for a recruiting campaign includes four parts:
- The recipient's actual first name
- A message specific to the trade and the work
- Credible employer branding
- One clear action, such as a QR code with a short URL
For a wider radius, address distance directly. Say where the work is, and speak to commute or relocation if it applies. For a single county, lean on being local.
How do you measure results across different geographic scopes?
You measure them the same way at any scope: QR scans and landing-page traffic show what the campaign produced, so you are not guessing.
A single-county test gives you a clear read
If a tight campaign produces enough interest to fill the role, you have your answer. If it does not, the response data tells you the geography was likely too narrow, and you can widen it for the next round.
Multi-county campaigns show where interest comes from
When you mail several counties, you can see which areas generated the strongest response. That helps you refine the boundary for later hiring instead of repeating the same assumptions.
The tracking does not change with the radius
Whether you mail one county or several, the response mechanism stays the same. The card carries one clear action, and what happens after the scan is visible to you.

What questions should you ask before you decide?
Ask five practical questions before you set the boundary, and let the answers decide between a tight audience and a wider one.
- How many licensed plumbers are in my target county? A very small number points toward a wider radius.
- Where is my job site, and what is a realistic commute or relocation distance? This sets the true boundary of your labor market.
- Am I filling one role now, or do I expect ongoing hiring? Ongoing hiring can support a tighter, repeated audience.
- How far will plumbers in my market travel for the right opportunity? Your own experience here is valuable evidence.
- Do I have flexibility to expand if one county does not produce enough response? Knowing this in advance lets you plan a first test and a follow-up.
Frequently asked questions
Is one county ever enough for a plumbing role?
Yes. If your county has a healthy number of licensed plumbers and your site is reachable from most of it, one county can be enough. It is a reasonable first campaign, especially for a permanent role at a fixed location.
Can a campaign reach plumbers who might relocate?
It can. A wider geographic audience combined with a message about the move gives candidates outside your commute zone a reason to respond. Make the relocation point clear on the card and the landing page.
Can I mail across several counties or nationwide?
Yes. RecruitCard handles single-market campaigns and nationwide rollouts. The scope you choose should follow your hiring need and the size of the local pool.
How do I know which counties worked?
Response is tracked through QR scans and landing-page traffic. That lets you compare activity and use it when you plan the next round.
Does RecruitCard handle the design and printing?
Yes. The service is managed end to end: audience targeting, card design, printing, postage, delivery, and response tracking.
