March 13, 2026
If you need to expand your business in the United Kingdom or contact clients, suppliers, or collaborators, it is important to know what the UK prefix is and the advantages it can bring to your business. The prefix allows you to identify the destination country and is the first step to being able to call the United Kingdom correctly.
In addition, more and more companies operating in the British market are choosing to have a number with a UK prefix to make it easier for customers to contact them.
In today’s article, we talk about the UK prefix and the advantages of using it with providers such as Megacall.
How Megacall helps you get a UK prefix number from abroad
Having a number with a UK prefix (+44) can be a very useful tool for companies that work with clients or teams in the United Kingdom. In many cases, having a local number that operates through VoIP makes communication easier, improves customer trust, and prevents international calls from becoming a barrier in communication.
At Megacall, we offer a wide variety of UK prefixes for companies and individuals, with the possibility of setting up a local phone number in the country.
- Local UK phone numbers – UK prefixes
We are talking about virtual numbers that work through VoIP telephony. Since they are not linked to a fixed location, this allows you to have a local number with a UK prefix even when you are abroad. They can be used to both make and receive calls on any device such as a mobile phone, tablet, or computer. They are especially helpful for companies or entrepreneurs operating their businesses from outside the United Kingdom.
With a provider like Megacall, you can set up a UK prefix in minutes, only a device and a good internet connection are required. There is wide geographic coverage of virtual phone numbers available, with the United Kingdom being one of the most popular.
What are the advantages of using VoIP services for a UK prefix?
Using VoIP technology to obtain a number with a UK prefix offers many more possibilities than a traditional telephone line. Why? Because instead of depending on physical infrastructure, the number works through the internet, which allows it to be managed much more flexibly and adapted to the needs of each company.
This is where all the benefits of using a UK prefix with VoIP come from:
Status and credibility
Having a number with a UK prefix conveys proximity and trust to customers in the United Kingdom. When a company uses a local number, users perceive that they can easily get in touch and that there is a real presence in the country. This can encourage potential customers to call or request information, especially in sectors where telephone support remains an important channel.
Management tools
Another very important advantage to highlight is that you can connect your virtual number with a UK prefix to Megacall’s virtual PBX. This allows access to multiple tools to manage and organize calls more efficiently.
For example, you can configure automated customer service menus, call queues, opening hours, extensions for different departments, call recording, and even if you want to cover times when no one is available to answer calls, there is the possibility of connecting an AI voice agent, either natively through the Megacall PBX or through integrations with Retell AI, Vapi, and ElevenLabs.
Megacall also allows users of its platform to access its CRM for free.
Marketing
We can also gain advantages when it comes to marketing strategies in the British market. Including a local phone number in campaigns or commercial materials can increase the contact rate. In addition, since the number is connected to the Megacall PBX, it is possible to obtain data such as the most frequently used keywords, agent mistakes, the most common questions, and more. This makes it possible to draw conclusions based on real data to improve sales or overall service.
Flexibility
Flexibility is one of the main advantages of UK prefixes through VoIP. Calls that arrive at the UK prefix number can be directed to different devices such as mobile phones, computers, or tablets. With Megacall, this is possible thanks to its applications that allow the use of a softphone on any device connected to the Internet.
In addition, the configuration can be easily modified according to the needs of each company. For example, new extensions can be added or the system can be adapted to the call volume. This allows the solution to evolve together with the business.
Cost-effectiveness
Using numbers with a UK prefix -and virtual numbers in general- is more cost-effective than traditional telephony solutions, especially when operating in multiple countries, since complex installations are not required.
This allows SMEs and freelancers to have a number with a UK prefix with a lower investment, which is particularly interesting for companies that are just starting to operate in the British market.
How to dial a UK number from Spain
Whether you need to contact clients for work, business, or suppliers, it is important to know the UK prefix and how to dial it correctly.
In addition to traditional dialing, VoIP alternatives and virtual numbers can help you save a lot when making international calls. Calling landlines with a UK prefix from Spain is very simple if you follow the correct format.
- Dial Spain’s exit code: 00
- Then add the UK prefix: 44
- Remove the “0” from the UK area code: for example, Manchester 016. When calling from outside the country, it becomes 16.
- Finally, enter the landline phone number.
Example: Calling Manchester from Spain
The dialing format would be:
00 – 44 – 16 – XXXX XXXX
