Choosing Your Business Number

The right phone number builds trust, improves response rates, and supports your business growth.

Choosing Your Telephone Number

The phone number you choose says a lot about your business. It affects how customers see you and how likely they are to call.

Local 01 and 02 numbers are regulated by Ofcom, they build trust in specific areas. 0333 numbers give you a consistent national presence. 0800 numbers remove the cost of calling and can increase enquiries.

Not sure which number range is right for you? We’re rated 5-stars for a reason, just call us on 0800 772 0000 and we’ll listen to your business needs and advise the best options.

01 & 02 Numbers

Our most popular range for businesses in the UK.

A geographic phone number (01 or 02) gives your business a trusted local identity anywhere in the UK. Customers instantly recognise these numbers as familiar, standard-rate landlines, which can increase answer rates and build confidence when they decide to call.

Our local numbers are Virtual, so no fixed landline needed. Calls can be connected to your mobile, landline or VoIP system, allowing you to work from anywhere while still presenting a professional local presence. You can choose a number in the area you operate.

Commonly used for

01, 02 virtual landline numbers

0800 Numbers UK

Freephone numbers allow customers to call your business at no cost to them, removing one of the biggest barriers to getting in touch. When callers know the call is free from both landlines and mobiles, they are far more likely to enquire, request a quote or respond to your advertising.

An 0800 number instantly positions your business as established, professional and customer-focused. They are particularly effective for companies running marketing campaigns, as a memorable Freephone number can improve response rates and maximise return on ad spend.

Our 0800 numbers are fully virtual, meaning calls can be routed to your mobile, office landline or VoIP system. You’ll also benefit from features such as call reporting to help you track how well your numbers is performing.

Commonly used for

Memorable 0800 numbers

0333 Numbers UK

0333 numbers are national, non-geographic telephone numbers charged at standard UK call rates, making them an accessible and professional option for businesses of all sizes. Unlike traditional 01 or 02 numbers, an 0333 number is not tied to a specific town or city, allowing you to promote your services across the UK while presenting a single, consistent contact number.

Calls to 0333 numbers are included in most call packages,  so customers can call you at no extra cost. This makes them a strong alternative to 0800 numbers for businesses that want a national presence without covering inbound call charges.

Our 0333 numbers are fully virtual, meaning calls can be routed to mobiles, office landlines or VoIP phone systems. With features such as Hunt Groups & Timed Diverts you can set your number up to work for your whole team.

Commonly used for

Nantional Presence 0333 Numbers

0300 Numbers UK

0300 numbers are national, non-geographic telephone numbers charged at standard UK call rates and are reserved exclusively for charities, public sector bodies and not-for-profit organisations. They provide a single, consistent contact number that works nationwide, without being tied to a specific town or region.

Because 0300 numbers are regulated and restricted to eligible organisations, they give callers confidence that they are contacting a recognised charity or public service rather than a commercial business. Calls are charged at the same rate as calling an 01 or 02 number and are included in most mobile and landline call packages.

Our 0300 numbers are fully virtual, allowing calls to be routed to your office, remote teams or VoIP phone system. Features like hunt groups mean you can send calls to multiple people.
