Every piece of marketing you produce — every leaflet, every Google ad, every directory listing — asks the customer to do something. And the phone number you put on that material directly affects whether they do it. Research consistently shows that local area codes generate higher answer rates, more inbound calls, and better conversion than mobile numbers, non-geographic numbers, or withheld numbers. Here's why, and how to use local numbers strategically across your marketing.

Local Numbers Get Answered More Often

The single biggest factor in marketing response is whether the customer actually engages. For phone-based marketing, that starts with whether they answer the call or make the call in the first place. And the number they see makes a dramatic difference.

Research by Software Advice found that people are nearly four times more likely to answer a call from a local area code than from a toll-free or non-geographic number. Specifically, 27.5% of people answer calls from local numbers, compared with just 7% for toll-free numbers. That's the difference between roughly one in four and one in fourteen.

Businesses that implement local presence dialling — displaying a local area code that matches the recipient's region — consistently report answer rate improvements of 300–400%. One case study documented a 400% increase in appointment setting after switching from a generic number to local area codes.

The reason is straightforward: people screen calls. With 32% of unknown calls to UK mobiles now being spam according to Hiya's Global Call Threat Report, and UK fraud losses from scam calls reaching £1.17 billion in 2024, consumers have learned to be suspicious of unfamiliar numbers. A recognisable local area code cuts through that suspicion because it looks like a call from someone nearby, not a sales operation in a distant call centre.

A Local Number on Your Marketing Generates More Inbound Calls

It's not just about outbound calls. When a local number appears on your marketing materials, more customers pick up the phone and call you. The data shows why:

  • 50% of consumers would call a landline first when given a choice, compared with just 6% who'd choose a mobile (Zen Internet)
  • 35% of consumers wouldn't trust a business that only uses a mobile number
  • 48% of UK consumers trust businesses more if they have a landline — rising to 54% among Millennials
  • 67% of customers prefer to contact businesses by phone over any other channel (Communications Management Association)

When your leaflet, van signage, or local newspaper ad shows a recognisable area code, the customer sees a local business they can trust. That perception translates directly into more calls. Using local geographic numbers has been shown to increase call volume by over 200% compared with generic or non-geographic alternatives.

The maths: If your current marketing generates 50 calls per month, and switching to a local number doubles your call volume to 100, that's 50 additional enquiries. At a phone call conversion rate of 25–40%, that's 12–20 extra customers per month — from changing nothing except the number on your marketing.

Phone Calls Are Your Highest-Converting Marketing Channel

Not all marketing responses are equal. A phone call is worth far more than a website visit, a form submission, or a social media click. The conversion gap is enormous:

Response Channel Typical Conversion Rate Relative Value
Inbound phone call 25–40% Highest intent, most likely to buy
Click-to-call from search 5–25% High intent, immediate action
Web form submission 1–3% Moderate intent, may go cold
Website visit (no action) <1% Low intent, browsing

Phone calls convert at 25–40% — up to 20 times better than web-based leads. And 65% of businesses say their most valuable leads come from phone calls, with phone leads converting to customers 10–15 times more often than web leads.

This means that anything you do to increase the number of phone calls your marketing generates has a disproportionate impact on revenue. A local number does exactly that: it makes the phone call feel easier, safer, and more natural for the customer.

How Local Numbers Improve Each Marketing Channel

A local area code strengthens every marketing channel where a phone number appears. Here's how it works across the channels most UK small businesses use:

Google Business Profile & local search — 88% of consumers who search locally on mobile visit or call within 24 hours. A local area code on your Google listing confirms you're genuinely local, encourages click-to-call, and strengthens your NAP consistency for better rankings. Businesses with consistent NAP data are 40% more likely to appear in the Local Pack.
Google Ads with call assets — Adding call extensions to Google Ads can increase click-through rates by up to 15%. A local number in those extensions looks more relevant to the searcher than a mobile or national number, especially for location-specific searches like "electrician near me."
Leaflets & direct mail — The DMA reports an average 4% response rate for direct mail, with warm campaigns reaching 7.9%. A local number on your leaflet makes the business feel nearby and established. More importantly, it gives you something to measure — a dedicated local number per campaign lets you track exactly which drops generate calls.
Vehicle signage & outdoor advertising — People see your van or sign for seconds, not minutes. A local landline number is easier to remember and more trustworthy than a mobile number. It tells passing customers you're a local, established business worth calling.
Online directories & listings — Yell, Thomson Local, Checkatrade, Bark — every listing that shows your phone number is a potential customer touchpoint. A consistent local number across all directories strengthens your SEO and gives customers the confidence to call. For more on this, see our article on how local numbers help your Google rankings.
Social media profiles — Your Facebook page, Instagram bio, and LinkedIn profile all display contact information. A local landline looks more professional than a mobile, and 44% of consumers say calling is their preferred way to communicate with businesses.

Use Different Local Numbers to Track What's Working

One of the most powerful marketing advantages of virtual local numbers is the ability to use a different number for each campaign or channel. When each marketing activity has its own number, you know exactly which one generated the call.

Marketing Channel Dedicated Number What You Learn
Leaflet drop in Coventry 024 7xxx xxxx How many calls the leaflet generated
Google Ads campaign 0121 xxx xxxx Which ad keywords drive phone calls
Van signage 01902 xxx xxx Whether people actually call from seeing your van
Local newspaper ad 0161 xxx xxxx Whether print advertising is worth the spend
Yell listing 0113 xxx xxxx How many leads your directory listing produces

This is basic call tracking, and it solves one of the oldest problems in marketing: knowing which half of your budget is working. Without call tracking, you're guessing. Marketers who don't track phone calls can't accurately account for 50% or more of the conversions their campaigns drive.

With Virtually Local, each additional number costs from £4.95 per month. For the price of a coffee, you can track whether a £500 leaflet campaign actually generated any calls. That's marketing intelligence that pays for itself many times over.

Practical tip: Start simple. Use one number on your website, a different number on your leaflets, and a third on your van. After a month, check which number received the most calls. You'll know immediately where to invest more — and where to stop wasting money.

Target Different Areas With Area-Specific Numbers

If your business serves multiple areas, using area-specific numbers in your marketing lets you target each location with a number that feels local to those customers. This is geographic marketing at its simplest and most effective.

Consider a bathroom fitter based in Birmingham who also serves Solihull, Coventry, and Wolverhampton. Instead of using a single 0121 number across all marketing, they could use:

  • 0121 for Birmingham leaflets — The home area code. Customers recognise it instantly as local.
  • 0121 for Solihull campaigns — Solihull shares Birmingham's area code, so the same number works.
  • 024 for Coventry marketing — A Coventry number on Coventry leaflets makes the business feel local to Coventry customers.
  • 01902 for Wolverhampton ads — The right area code removes the perception that this is an "out of area" business.

All four numbers forward to the same mobile. The fitter answers the same way regardless of which number rang. But the customer in Coventry sees a Coventry number and thinks "that's a local company" — and is significantly more likely to call.

This approach is especially effective for businesses that advertise on platforms like Checkatrade, Bark, or MyBuilder, where customers compare multiple options side by side. The business with the local area code looks more established and more relevant than one showing a mobile number or an area code from a different town. For more on this strategy, see our article on how virtual numbers let you appear local anywhere in the UK.

Measuring the Return on Your Marketing Spend

The combination of higher call volumes and higher conversion rates means local numbers have a measurable impact on marketing ROI. Here's a simple worked example:

Metric Mobile Number Local Landline Number
Leaflets distributed 5,000 5,000
Response rate 0.5% (low trust) 1.5% (local trust)
Phone calls received 25 75
Conversion rate 25% 30%
New customers 6 22
At £300 avg. order value £1,800 £6,600

Same leaflet, same distribution, same offer. The only difference is the phone number. The local number triples the calls, slightly improves conversion (because callers already trust the business), and generates £4,800 more revenue. The virtual number costs £4.95 per month.

Even if the real-world improvement is more modest, the principle holds: a local number removes friction from the response, and less friction means more calls, more customers, and better return on every pound you spend on marketing.

The Bottom Line

Your phone number is part of your marketing. It's on every leaflet, every ad, every listing, and every search result. And the research is clear: a local area code generates more calls, higher answer rates, and better conversion than a mobile number or a non-geographic number.

Local numbers work because they trigger trust and familiarity. They cut through spam suspicion. They confirm you're a local business worth calling. And when you use different local numbers for different campaigns, they give you the tracking data to know exactly which marketing is working and which isn't.
