Why Do You Need an 0345 Number for Your Business?

The UK’s telecom framework can be complex, with countless telephone number prefixes and plan offers. Among the most popular for businesses is the 0345 prefix. You have undoubtedly seen them used by banks, retailers, and service providers.

But what are they, and why should your business use one? This guide explains the benefits of 0345 numbers, how much they cost customers to call, and how you can get one.

Quick Answer: Why Get an 0345 Number?
Yes, most UK businesses should get an 0345 number. It gives your company an instant national, professional image (not tied to a local area code) and is low-cost for customers to call. By law, 0345 numbers are included in all mobile and landline bundled-minute plans, just like a standard 01 or 02 number.

What Is an 0345 Number?

An 0345 number is a “non-geographic number” in the UK. Unlike 01 or 02 numbers (like 020 for London or 0161 for Manchester), it is not tied to any specific town or city. This allows you to have a single, national number for your entire business.

The most important fact about 03 numbers (including 0345, 0330, 0370, etc.) is set by Ofcom, the UK regulator. Ofcom mandates that calls to any 03 number must be charged the exact same rate as calls to standard geographic landlines (01 and 02 numbers). Crucially, they must be included in any free call bundles or inclusive minutes on mobile or landline plans.

Key Benefits of an 0345 Number for Your Business

0345 numbers are popular for a reason. They provide significant advantages to both the business and its customers.

• National Presence: An 0345 number instantly makes your business look larger and more professional. Customers from all over the UK will see you as a national company, not just a small, local shop.
• Low Cost for Customers: This is the biggest benefit. Because these numbers are included in call bundles, most customers can call you for free. This removes any fear of high charges, encouraging more calls, which leads to more sales and better customer service.
• Increased Trust and Credibility: Unlike 0800 numbers (which customers can’t always call for free from mobiles) or premium 0845/0870 numbers, the 0345 prefix is widely trusted as a standard, low-cost business number.
• Flexibility and Call Management: 0345 numbers are “virtual.” This means you can route calls to any landline or mobile phone you want, wherever you are. You can set up smart routing (e.g., “press 1 for sales”), track your call data, and manage everything from a simple online dashboard.

How Much Do Customers Pay to Call an 0345 Number?

This is the most common question. As mentioned, the cost is set by Ofcom, not the phone companies themselves.

This means for a customer on any network, whether it’s EE, O2, Vodafone, Three, or a landline provider like BT, the rule is the same:

• If they have a call bundle: If their plan includes a certain number of minutes to UK landlines (01 or 02 numbers), then calls to your 0345 number will be deducted from that same bundle. For most people, this means the call is effectively free.
• If they do not have a bundle: If they pay as they go, the call to your 0345 number will be charged at their standard landline rate, no more. There are no extra “service charges” or premium fees.

This is what makes 0345 numbers so customer-friendly and a great choice for your business.

How to Get an 0345 Number for Your Business

Getting an 0345 number is simple. You get them from a VoIP (Voice over IP) or cloud communication provider.

These virtual number providers operate online and offer a variety of numbers. Because the numbers are “in the cloud,” it’s very easy for you to manage your calls. You can:

• Choose your own “memorable” number.
• Forward all 0345 calls to your personal mobile, your office landline, or a remote team member.
• Set up welcome menus and voicemail-to-email services.
• Add or remove numbers as your business grows.

These services are typically very low-cost, flexible, and give you powerful tools to manage your business calls without needing any special hardware.

Conclusion

You now have all the information about 0345 numbers. They provide a huge number of benefits for your business by making you look more professional and making it cheap (or free) for your customers to contact you. If you want to build a national brand and encourage more customer interaction, you should get one right away.

Frequently Asked Questions (FAQ)

What is the difference between 0345 and 0800?

An 0800 number is a “Freephone” number. It is always 100% free for the person calling from any UK landline or mobile. However, the business owner pays a fee to receive that call. An 0345 number is low-cost for the caller (included in their bundles), and it is also very cheap for the business owner to run, often just a small monthly fee.

Are 0345 numbers free on EE?

They are “free” if you are an EE customer and your plan includes bundled minutes to UK landlines (01 or 02 numbers). The call to an 0345 number will simply use those minutes. This is true for all UK providers, not just EE, as it is an Ofcom regulation.

Do 0345 numbers look professional?

Yes. 0345 numbers are widely used by major, trusted UK businesses, including banks, insurance companies, and national retailers. Using one makes your business appear established, credible, and national in scope, rather than tied to a small, specific town.
