Frequently asked questions

  • Why do I need a 03 number

    Clients can reach your business at the cost of a local call from anywhere within the country on a 03 number.

    You can improve your sales by making a professional first impression to your customers with well-known business 03 number compared to a common number.

    A 03 number can be kept for the life of your business, regardless of what Telco you use. Even if you move to a different provider, a number still will be yours — whereby your regular customers and partners can always get through to you.

  • How many 03 numbers can I have?

    You can sign up for as many numbers as required. Many businesses use multiple 03 numbers to track performance of their advertising campaigns and alike.
