Phone Numbers
Pick from 4 million numbers from a range of geographical areas.
UK Geographic Numbers
UK Geographic numbers are used by businesses to let the calling party know where they are located. For example, an 020 number would identify with a business being located within London .
The great thing about using VoIP technology is that businesses can have a range of as many different geographic numbers as they like, making it look like you have offices all over that area or across the whole of the UK. When somebody calls one of these numbers, the call automatically comes back to your existing office and displays which number has been called so you can answer with the appropriate office location.
UK Non-Geographic Numbers
When choosing a Non-Geographic Number, it’s important to consider who you’re receiving calls from.
0800 & 0808 freephone
Our 0800 freephone numbers are the ideal choice for sales organisations. By not charging the caller for the cost of the call, this could encourage the caller to call you as opposed to your competitors. For low to medium call volumes, the cost to you for receiving calls will be 4p/min. If you’re receiving high call volumes, call our Sales Team to discuss this in more detail. Receiving calls from payphones carries an additional charge of £1/min, however payphones can be blocked on our network so you won’t get caught out by this charge.
0333
This is an excellent number to use for customers to call in on. No additional cost to the caller, just the standard local call charge. You can also call the numbers as part of a talk plan/inclusive minutes from a mobile phone on most networks.
0843/4/5
These numbers are great for administration lines or support lines. There is a small amount of revenue generated from the caller who will pay 7p/min. This is a great way to subsidise the cost of running your telephone services.
0870/1/2
Ideal for use in the service industry or for helplines. Calls cost 13p/min, generating a larger revenue for you to put towards running the services you offer. It may pay towards a support line where customers may not have a contract but would like help on a pay-as-you-go basis.
International Numbers
NTA can offer numbers from over 50 countries around the world, giving your business an international presence. This allows callers in these countries to call you for the cost of a local/national call from their telephony provider.
