0345 numbers have become a popular calling medium for enterprises, financial institutions, utility providers, government bodies, and mid-to-large businesses in the UK. They help organisations create a national presence without tying the business phone number to a specific city or local area code.
But what are 0345 numbers, are 0345 numbers free, and does your business really need one? This guide explains how 0345 numbers work, how much they cost from mobiles and landlines, which companies use them, and when a 0345 number is the right choice for your communication strategy.
Are 0345 Numbers Free?
0345 numbers are not freephone numbers. They are UK-wide non-geographic numbers that usually cost the same as calling a standard 01 or 02 landline number. In many UK mobile and landline plans, calls to 0345 numbers are included in bundled minutes. However, callers should always check their specific provider plan to confirm the actual charge.
For regulatory clarity, Ofcom’s 03 number guidance states that calls to 03 numbers cost no more than calls to 01 or 02 numbers and must count towards inclusive minutes in the same way.
What Is a 0345 Number?
A 0345 number is a UK non-geographic phone number. Unlike traditional landline numbers that begin with area codes such as 020, 0161, or 0113, a 0345 number does not reveal the physical location of your business.
This makes 0345 numbers useful for businesses that serve customers across the UK. Instead of showing a city-based identity, the number creates a national point of contact that works across branches, teams, departments, and customer service locations.
In simple terms, a 0345 number gives your business a central phone identity. Customers can call the same number whether your agents work from one office, multiple UK branches, or a cloud-based support setup.
Why Do Businesses Use 0345 Numbers?
Businesses use 0345 numbers because they are professional, flexible, memorable, and suitable for national communication. They are especially useful for companies that do not want customer calls tied to one local area.
1. UK-Wide Presence
A 0345 number allows customers across the UK to reach your business easily, regardless of where they live. This benefits companies with a nationwide reach, multi-location operations, or plans to expand into new regions.
2. Better Brand Consistency
A single 0345 number can appear across your website, advertisements, invoices, packaging, emails, and support pages. Customers do not need to choose between multiple local numbers, and the business can maintain one consistent contact identity.
3. Flexibility and Scalability
By getting 0345 numbers for your business, you do not need to acquire new phone numbers with different area codes whenever you grow. A 0345 number can act as your central point of contact while calls are routed to the right teams behind the scenes.
4. Improved Customer Experience
By offering a consistent and memorable contact number, you can create a professional image and elevate customer experience for your clients. Customers get one reliable number, while your team can manage calls through routing, IVR, call recording, and reporting.

Which Companies Use 0345 Numbers?
The versatility of 0345 numbers makes them suitable for a wide range of businesses across various sectors. Here are some examples:

Financial institutions
Entities like banks, insurance companies, and financial institutions often use 0345 numbers for smooth customer support services. 0345 numbers enable such institutes to reinforce trust and professionalism when dealing with sensitive financial matters.
Utilities
Many utility providers like gas and electricity companies frequently use 0345 numbers for customer service and account management. These numbers ensure customers have a centralized contact point for enquiries, meter readings, or troubleshooting issues.

How Much Does a 0345 Number Cost?
A 0345 number’s cost varies depending on the service provider you choose, the features included, and whether the number is part of a cloud phone system package. At Acefone, you can get a 0345 number for your business for as low as £4.99. Alongside 0345 numbers, businesses can also access 50+ cloud-based features to make inbound and outbound communication easier to manage.
When comparing providers, do not evaluate only the monthly number rental. Look at the full value of the plan, including call routing, IVR, analytics, call recording, number porting, CRM integrations, user access, uptime, and support.
Are 0345 Numbers Free to Call from Mobile?
0345 numbers are not automatically free to call from mobile phones. However, the call cost usually falls in the same price band as calling a standard UK landline number beginning with 01 or 02.
Many UK mobile providers include calls to 0345 numbers within bundled minute allowances. If the caller has inclusive minutes, the 0345 call may be covered under that allowance. If not, the mobile provider may charge a per-minute rate. For transparency, businesses should avoid calling 0345 numbers “free” and instead explain that they are charged like standard landline numbers.
Are 0345 Numbers Free to Call from Landline?
Similar to mobile calls, calling a 0345 number from a landline depends on the caller’s phone plan. In most cases, calling a 0345 number from a UK landline is charged at the same rate as calling a standard 01 or 02 number.
If a landline plan includes calls to UK geographic numbers, calls to 0345 numbers are often included too. However, callers should confirm with their phone provider, especially if they are calling from abroad, from a payphone, or outside a bundled call allowance.
0345 Numbers vs 0800, 0333, and Local Numbers
| Number Type | Best For | Caller Cost | Business Use |
|---|---|---|---|
| 0345 | National businesses, support lines, financial services, utilities | Usually same as 01/02 numbers and often included in bundles | Professional nationwide number without a local area code |
| 0800 / 0808 | Sales lines, support teams, customer-first brands | Free for callers from mobiles and landlines | Business pays to encourage more inbound calls |
| 0333 | National organisations and general business support | Usually same as 01/02 numbers and often included in bundles | Similar national presence without location identity |
| 01 / 02 | Local branches and region-specific businesses | Standard geographic call rates | Builds local trust in a specific city or area |
If your business wants customers to call without paying, a freephone number such as 0800 may be more suitable. If you want a cost-effective national number that still feels professional, a 0345 number can be a better fit.
Does Your Business Need a 0345 Number?
Whether a 0345 number is the right fit for your business depends on your target audience, call volume, brand positioning, and customer service model. Here are the main factors to consider.
1. Choose a 0345 Number If You Need National Reach
If your business caters to customers across the UK, a 0345 number can project a professional and accessible image regardless of customer location. It eliminates the need for multiple local numbers and simplifies communication across marketing channels.
2. Review Call Costs for Customers
0345 numbers are generally cost-effective, but they are not freephone numbers. If affordability for callers is central to your brand promise, you may want to compare 0345 numbers with 0800 numbers before making a final choice.
3. Think About Branding and Memorability
A 0345 number can contribute to a consistent brand image across websites, ads, email signatures, brochures, and support pages. Having one number improves recall and reduces confusion for customers.
4. Assess Your Existing Phone Infrastructure
If you already have a well-established local landline number with strong local recognition, moving to a 0345 number may require customer communication. You can also keep existing numbers and route them into a modern cloud phone system.
5. Plan for Call Routing and Team Growth
A 0345 number becomes more valuable when combined with cloud features such as call forwarding, IVR, analytics, voicemail, and agent routing. Acefone’s VoIP phone service helps businesses migrate existing numbers, set up virtual extensions, and use modern calling features such as analytics, IVR, and global calling flexibility.
How to Set Up a 0345 Number for Your Business
Setting up a 0345 number is usually straightforward when you choose a telecom or cloud communication provider.
- Choose your preferred 0345 number provider.
- Select the number or number range that suits your business.
- Map the number to departments, agents, offices, or remote teams.
- Configure routing rules, business hours, voicemail, and fallback options.
- Add IVR menus if you need self-service or department-level routing.
- Test inbound calls from mobile and landline devices before launch.
- Update the number across your website, ads, email signatures, invoices, and customer portals.
For growing teams, adding an IVR service can help route callers to sales, support, billing, or technical teams without manual transfers.
Best Practices for Using 0345 Numbers
- Be transparent: avoid saying 0345 numbers are free; say they are charged like standard 01/02 landline numbers and may be included in bundled minutes.
- Use one primary 0345 number across key brand touchpoints for consistency.
- Set up clear call routing so customers reach the right department quickly.
- Use call recording and analytics to improve service quality.
- Add fallback routing to mobile or remote teams during busy hours.
- Monitor missed calls and callbacks to reduce lost enquiries.
- Review call reports regularly to understand peak times and staffing needs.
The Takeaway
0345 numbers offer a practical option for businesses seeking to establish a national presence and streamline customer communication. They are not free to call, but the cost typically falls within the same range as calling a standard 01 or 02 landline number.
Mobile network providers and landline packages often include calls to 0345 numbers within bundled allowances, but caller costs depend on the specific provider and plan. Businesses should communicate this clearly to avoid confusion.
Choose a 0345 number if you prioritise national reach, brand consistency, scalability, and cost-effective access for customers. Choose an 0800 or 0808 number if your priority is making inbound calls free for the caller.
By carefully evaluating your target audience, call volume, customer service needs, and existing infrastructure, you can decide whether a 0345 number is the right fit for your communication strategy.
