An iNum is a new kind of global phone number that is not tied to any country or location. It uses a new +883 global country code that was recently created by the ITU (International Telecommunication Union). An iNum offers several compelling advantages:

• It is a global phone number that will be able to be called from anywhere in the world
• It is a portable phone number in that it is not tied to a specific country
• Calls to an iNum can be free from some service providers and may be inexpensive from other providers
• It is reachable from both the traditional Public Switched Telephone Network (PSTN) and also from Voice-over-IP (VoIP) providers

The +883 country code used for iNums is still in the process of being deployed globally across the existing PSTN. As a result, users in some countries may not be able to dial an iNum directly on their existing PSTN carrier. To assist users whose carriers do not yet support the +883 country code, Voxbone, the carrier behind the iNum initiative, has set up local phone numbers in 45 countries. For Luxembourg, this number is +352 20880108. Simply dial this local access number and dial the chosen iNum afterwards.

iNum is an initiative launched by Voxbone, supplier of local telephone numbers to communications services providers and businesses worldwide. Voxbone is a privately held company with offices in Brussels, Singapore and Los Angeles.

An iNum will be automatically assigned to developers of a new application on the free VoiceXML VOXEO platform.
