How to Choose the Right Area Code for Your Business

Your area code is more than a string of digits. It tells customers where you are, shapes their first impression, and influences whether they pick up the phone. With over 610 geographic area codes available across the UK, choosing the right one matters — whether you're setting up your first business number or expanding into new markets. Here's how to make the right choice.

Start With Your Customer, Not Your Address

The most common instinct is to choose the area code for where your business is based. And for many businesses, that's exactly right. But the better question is: where are your customers?

Your area code is a signal aimed at the person calling you, not a label for your office. If your customers are primarily in one area, you want the area code they recognise as local. That might be the town you're based in — or it might not.

Consider these scenarios:

• A web designer in Solihull whose clients are mostly in Birmingham — an 0121 number makes more sense than using a mobile, since Solihull shares Birmingham's area code anyway.
• A consultant who lives in Cheshire but whose clients are in Manchester — an 0161 number positions the business where the clients are.
• An accountant working from home in a village outside Leeds — an 0113 number connects the business to the city where most clients are based.

UK numbering rules don’t require a geographic number to be answered at an address in that area — out-of-area use of geographic numbers is an accepted, long-standing practice, and it’s exactly how virtual numbers work. There's nothing misleading about it as long as you genuinely serve the area — you're simply choosing a number that reflects where you serve, not just where you sit.

Understanding Your Number Options

Before choosing a specific area code, it's worth understanding the different types of UK business numbers and what each one signals to customers:

For most small and medium businesses that serve customers in a specific area, a geographic 01 or 02 number is the strongest choice. Most people recognise 01 and 02 numbers as ordinary local landlines, and calls to them are typically included in mobile and landline call allowances. Customers trust them because they're familiar, and they're especially valued when someone is searching for a business close to home.

The number people see really does affect their behaviour. Ofcom found that over 90% of mobile users decide whether to answer a call based on the number displayed on the handset at least some of the time^[1]. And in a Censuswide survey for Zen Internet, 35% of Brits said they wouldn’t trust an SME that operates solely with a mobile number^[2]. For a deeper look at these preferences, see our article on why customers prefer calling local business numbers.

Matching Your Area Code to Your Market

The right area code depends on the shape of your business. Here's how to think about it based on the area you serve:

The UK's Key Business Area Codes

While every area code has value in its local market, certain codes carry additional weight because of the cities they represent. If you're choosing a number to project a strong business presence, these are the area codes that matter most:

A London 020 number, for example, carries a particular weight. It signals a capital-city presence that can be valuable for businesses in finance, law, consulting, or any field where London credibility matters. A Manchester-based tech startup might add a 020 number to win London clients, while keeping 0161 as its primary line.

But don't overlook smaller area codes. If your customers are in Exeter, an 01392 number is more powerful than a prestigious 020 because it tells Exeter customers you're local. The best area code is always the one your specific customers recognise.

The Multi-Number Strategy

One of the biggest advantages of virtual local numbers is that you're not limited to a single area code. You can use different numbers for different purposes, and they all forward to the same phone or team.

Here are the most effective multi-number strategies:

• One number per service area — If you're a tradesperson or service business covering multiple towns, use a different local number for each. Customers in each area see a number they recognise. You know which area generated the call.
• One number per marketing channel — Use different numbers on your website, leaflets, van signage, and directory listings. This gives you built-in call tracking — you'll know exactly which marketing is generating calls. See our article on how local area codes improve marketing response rates for more on this approach.
• Strategic city presence — A consultancy might use a 020 London number for its website, a 0161 Manchester number on its northern marketing, and a 0131 Edinburgh number for Scottish clients — all ringing the same team.
• Separate departments — Use one number for sales enquiries and another for existing customer support. Both can be local numbers, but forwarding to different people or teams.

Each additional number costs from just £4.95 per month with Virtually Local. There's no limit on how many you can have, and they're all managed through a single online portal. For a detailed look at this strategy, see our article on how virtual numbers let you appear local anywhere in the UK.

How Your Area Code Affects Local SEO

Your choice of area code has a direct impact on how well you rank in local Google searches. Google's algorithm uses your phone number as a location signal, and your NAP (Name, Address, Phone number) consistency across the web is a key ranking factor.

Here's what to consider:

The compounding effect matters: a local number helps you rank higher in local search results, which means more people see your listing, and the local area code on that listing makes them more likely to call. For a full guide, see our article on how local phone numbers help your Google rankings.

Common Mistakes to Avoid

Choosing an area code is straightforward, but there are a few pitfalls worth avoiding:

Already Have a Number on a Copper Line?

If your business already has a landline number running over a traditional copper line, the right area code may be the one you already own. The UK’s old analogue phone network (PSTN) is being switched off on 31 January 2027 — now just weeks away — and Openreach has said there is no extension to the deadline^[3]. Rather than lose a number customers have dialled for years, you can port it to Virtually Local free of charge; most ports complete within around a week. Our PSTN switch-off checklist for the final 12 weeks covers the steps.

Five Steps to Choosing and Setting Up Your Number

1. List where your customers are. Look at recent invoices, enquiries or delivery postcodes and note the two or three towns that come up most.
2. Look up the area codes for those places. Some neighbouring towns share a code (Solihull and Birmingham both use 0121); others don’t.
3. Pick your primary number. This is the one that goes on your website, Google Business Profile and directories — and stays there.
4. Add secondary numbers only where they earn their keep. A second area you actively market to, or a campaign you want to track.
5. Set your forwarding and greeting. Decide which phone each number rings, what happens out of hours, and how you’ll answer so callers know they’ve reached the right business.

If you’re new to how this works behind the scenes, our explainer on what a virtual phone number is and how it works covers the basics.

The Bottom Line

The right area code is the one your customers recognise as local. It builds trust before the phone even rings, strengthens your local search visibility, and makes people more likely to call. The wrong one — or no landline number at all — costs you enquiries you'll never know you missed.

With Virtually Local, you can choose from over 610 UK area codes, set up your number in minutes, and add more as your business grows. Each number costs from £4.95 per month with no setup fees and no contract. Calls forward to your mobile, so you answer wherever you are — but your customers see a local business they trust.
