03 nationwide numbers

How do 03 numbers work?

03 numbers are numbers which aren't connected to a landline. Not being tied to a landline gives virtual numbers great flexibility for you to control how and where you receive your calls.

When anyone calls your 03 number, the call comes into our advanced call management platform and from there the call is sent to wherever you want it to: a landline, a mobile, a VoIP device or even an international number.

Our online dashboard gives you real-time control of your numbers and gives you access to a wealth of features to help you to use your numbers most effectively. You can change where your number points to at the click of a button, get detailed statistics on your numbers and add extra features on demand.

How can 03 numbers help your business?

  • Project a more professional image by advertising a nationwide number instead of a mobile.
  • Attract more business from outside your local area.
  • Give your customers a cheaper alternative to calling 08 numbers. 03 numbers cost the same to call as standard landline numbers.
  • Gives your business the perception of being a larger organisation.
  • Control how and where incoming calls are handled to suit you.
  • Use the detailed call analytics to see how many calls are received on each number and how effectively your call handling team are performing.

There are many innovative ways in which virtual numbers can save your business money and give you greater control on how incoming calls to your business are handled.

Frequently asked questions

How long will it take to set up my 03 number?

Once you've chosen your numbers, it takes less than five minutes to set up your account and activate your number during normal working hours! If you're not an existing client and you purchase a number outside of normal working hours then the numbers will be activated first thing the following day.

How long is the contract for a 03 number?

We don't tie you into a contract and you can cancel your 03 number at any time. You can simply delete the number from your account via the online portal and your subscription will stop.

Do you charge for changing my redirect number?

No. You can change your redirect number using the online portal as many times as you like.

Are there any other hidden charges?

No. We're very proud of our clear and easy to understand pricing. Unlike some providers we charge our calls to the second with no call connection charges, minimum call durations, or rounding the duration of the call up to the next minute.

What payment methods do you offer?

We offer Paypal and Direct Debit.

Can I route my 03 number to a mobile phone?

Yes. You can redirect your number to any number of your choice: a landline, a mobile, or even an international number.

Can I route my 03 number to a VoIP device?

Yes. Each user account is VoIP enabled by default so you simply need to configure your device to register with our platform using the login credentials on your dashboard.

How many concurrent calls can I receive on my 03 number?

You can receive as many concurrent calls on your 03 number as you are capable of handling. You are only limited by the number of lines available to your target number.

How much does it cost to call an 03 number from a mobile?

Calls to 03 numbers from a mobile generally cost the same as a call to a normal landline.

I would like to port my existing 03 number to Invoco. Is this possible?

Yes. We simply require you to fill out a Letter of Authority to enable us to contact your existing provider and to start the process. The length of time it takes to port the number can vary significantly depending on whether or not we already have a porting agreement with your existing provider. For further information please contact our Sales Team. Some network providers will also charge an administration fee to port a number away from their network so you should also clarify this with your existing provider.

I would like to port my Invoco 03 number to another provider. Is this possible?

Yes. You will need to fill out a Letter of Authority with your new provider who will then contact us to commence the porting process. The length of time it takes to port the number can vary significantly depending on whether or not we already have a porting agreement with the new provider. There is a minimum service term of 12 months for numbers to be ported away from our network and we would charge a £20 administration fee.

Can my 03 number be called from overseas?

Possibly, but this can not be guaranteed. If you have overseas clients then it is advisable to offer them a standard landline alternative to call.

The UK's best loved telecom company for the 2nd year running!

A BIG THANK YOU to all of our customers who voted for us and enabled us to become recognised as the UK's best loved telecom company for the second year running!!


Come and see us on 3rd July at the NEC and have a chat about our latest call tracking and automation products to see how they can help your business.

Virtual Numbers

A virtual telephone number is a number which isn’t linked to a telephone line. If you’re running a small business, a virtual number is a great way to give yourself a more professional image, rather than using a mobile or home phone number.

For SMEs or global organisations, virtual numbers allow you to promote a local presence in the UK without having to physically be in that location. Our online call management system gives you unparalleled control of your numbers, a wealth of features and real-time statistics.

Call Tracking

Do you know how you win most of your business? Or do you spend money on newsletters, adverts and sales letters with no idea which of them work and which of them are money down the drain?

With our call tracking numbers you can use a specific phone number for a particular ad campaign, and find out how many people actually respond to your advert.

There’s no complicated adding up to be done. You’ll receive regular reports showing how many calls have been made to each of your tracking numbers.

Or go online and see, instantly, how many calls you've received on which numbers.

Virtual Landline

When you’re starting out, or running a micro-business, using a mobile phone or home landline as your business phone number is common practice. But most businesses eventually outgrow this setup and need something more professional and fit for purpose.

Hosted PBX

As your business evolves and grows, you need a telephone service that’s fit for purpose and keeps up with demand. With the right system you can provide exceptional customer service while your offices run more smoothly than ever before.
