Choose from a comprehensive range of UK telephone numbers — geographic, UK-wide, freephone, special rate, premium rate, and personal numbers — all delivered instantly over SIP.
Blue Telecoms offers a full portfolio of DDI (Direct Dial-In) telephone numbers to match your business requirements. Whether you want to appear local with a geographic number, offer free calls to your customers with an 0800 number, or generate revenue with premium rate numbers, we have you covered.
All numbers are provisioned instantly and work seamlessly with our SIP trunking service. Port your existing numbers or choose new ones — it's completely up to you.
Geographic numbers beginning with 01 or 02 are tied to a specific area code, allowing your business to establish a local presence in any part of the UK. With over 350 area codes available, you can choose numbers for London (020), Birmingham (0121), Manchester (0161), Cardiff (029), Edinburgh (0131), and hundreds more.
Customers are far more likely to call a local number, and geographic numbers give your business instant credibility in any region — even if you're based hundreds of miles away. Ideal for businesses that want to appear local to their target market without the expense of opening a physical office.
Appear local in any UK area
03 numbers are non-geographic UK-wide numbers that cost the same to call as a standard landline. They're included in callers' bundled minutes on both landline and mobile tariffs, making them an excellent choice for businesses that want a single national number without penalising their customers.
Unlike 08 numbers, 03 numbers cannot cost more than a call to a geographic 01 or 02 number, and must be included in any inclusive call packages. This makes them the preferred choice for organisations that want to be accessible and transparent — particularly customer service departments, government bodies, and national charities.
One number for the whole country
Special rate numbers allow your business to earn revenue from incoming calls at rates of up to 5p per minute. These numbers are ideal for support lines, information services, and any situation where call revenue helps offset the cost of providing a telephone service.
Special rate numbers that generate revenue of up to 5p per minute for your business. Callers pay a service charge in addition to their access charge. Suitable for commercial helplines, booking lines, and information services where revenue generation is important.
Another special rate number range generating revenue of up to 5p per minute. Popular with businesses that provide ticketing services, travel booking lines, and technical support. The service charge is set by the business and must be clearly displayed in advertising.
Historically known as "local rate" numbers, 0845 numbers now carry a service charge of up to 5p per minute plus the caller's access charge. Still widely used by businesses transitioning from legacy numbering, and recognised by callers as a standard business number.
0870 numbers also carry a service charge of up to 5p per minute. These numbers were traditionally used as "national rate" numbers and remain popular for businesses that want a national presence while generating a small revenue from incoming calls.
0871 numbers are premium rate numbers that charge callers 10p per minute (plus the caller's access charge). Your business can earn revenue of up to 8p per minute from every call received — making these numbers ideal for high-value information services, competition lines, and premium support services.
Businesses using 0871 numbers must register with PhonePayPlus (now the Phone-paid Services Authority, PSA) before the numbers can go live. This ensures compliance with UK regulations governing premium rate services and protects consumers from unexpected charges.
Blue Telecoms will guide you through the registration process and ensure your 0871 numbers are fully compliant from day one.

07 personal numbers provide a follow-me service that allows you to receive calls on any device without revealing your actual telephone number. When someone calls your 07 personal number, the call is automatically forwarded to whichever device you choose — your mobile, office phone, home phone, or softphone.
This is ideal for professionals, freelancers, and remote workers who want to maintain a single contact number while keeping their personal number private. Change the forwarding destination at any time without your callers needing to know — they simply continue dialling the same 07 number.
One number, any device
0800 numbers are free for callers from both landlines and mobiles, making them the best choice for businesses that want to maximise inbound call volumes. Customers are significantly more likely to call a freephone number than a charged number, making 0800 numbers essential for sales lines, customer service departments, and marketing campaigns.
Since 2015, Ofcom regulations require that 0800 calls are free from all UK mobiles as well as landlines. This means your 0800 number is truly free for every caller — removing all barriers to contact and helping your business attract more enquiries and generate more leads.
0800 numbers also project a professional, established image and are universally recognised as free-to-call. They're ideal for national advertising campaigns, direct response marketing, and any scenario where encouraging inbound calls is a priority.
Free for every caller, every time
