How do international numbers work?

All international phone numbers must be used with a Callagenix service. Once your chosen number has been activated, we instantly route your calls to your chosen service. Depending on the service you select, your call could, for example, be routed to your support centres, sales offices, or perhaps a voicemail message, emergency information line service, or fax to email. When combined with our Time of Day service you can truly set up and manage a global "follow the sun" service.

Charges are dependent upon the number type selected and the Callagenix service used. We offer numbers in over 100 countries - for a full international number country list click here.

You can read more about how UK regional numbers are used with our Advanced services on this page:

International Freephone Numbers (ITFS)

One of the most popular and powerful for promoting products and services, ITFS numbers are easily recognised in their country of origin as being free to call. ITFS numbers can also be known as international toll-free, or sometimes international freephone numbers.

Each country number will be different and they can generally only be called from the country they have been set up in.

Most ITFS numbers can be accessed by mobile callers. However, this is not guaranteed for all countries, or from all mobile networks. You can find more information on the International Freephone service on each individual country page, or please contact us if you need clarification.

International Regional Numbers (PSTN)

If you are looking to promote yourselves as having a regional presence around the world, Callagenix can provide you with a range of International Regional Numbers (PSTN).

For example, you could promote your products and services with a regional number in say, Paris, Beijing, Sydney and Zurich without actually being located there. Callers will dial the number in the same way they would call a local number in their country.

We now cover almost 4,000 local areas across some 100 countries. Unlike Freephone and National numbers, PSTN numbers can be called internationally by dialling the country code first and are fully accessible by all mobile callers.

International National Numbers

International National Numbers are generally either non-geographic, or are specially designated numbers, usually for the capital city.

The UK has a wide range of these numbers with a starting prefix of 03X, 08X, and 09X.  Some are revenue earning like 0871, 0872 0844 and 09xxx, whilst others with the prefix 03xx, 0845 and 0870 are not revenue generating. No revenues are payable on any International National numbers outside of the UK.

Callers will dial the number in the same way they would call that number in their country. These numbers are available in many countries all over the world. However, like freephone numbers, National numbers cannot always be called from outside the country of origin.

If you have any questions about how they work in a particular country please check out the individual country pages, or contact us.

International Numbers

Universal International Freephone Numbers (UIFN)

If you are looking to promote your products or services in many countries but only wanting to use a single toll-free international number, Callagenix can provide you with a UIFN, Universal International Freephone number. With a UIFN the phone number stays the same across all countries it is set up for, with only the freephone prefix changing for each country.

To name a few countries, you can use the same UIFN number in Australia, Belgium, France, Hong Kong and the UK without physically being in each location.

UIFN numbers are not available in all countries and the prefix dialled in each country can vary. Most UIFN numbers have the prefix 00 800, whilst some start 001followed by the rest of the number. Again, the numbers can only be dialled from within the country they have been set up in, but whilst all can be called from landlines, not all are accessible from mobile phones.

Requirements and Restrictions for International Numbers

While suitable ID is required to open a Callagenix account, some countries may require additional forms of ID. In some cases a signed letter stating your organisation's core activities may also be needed.

Additional notes covering specific requirements and restrictions are available once you have chosen your required number type. We will, of course, assist in any way possible to help you get set up as soon as possible.
