International premium rate numbers (IPRN) refers to internationally available telephone premium numbers. It is normal telephone number in a country with interconnection fee. Similar to "900" or "976" numbers in North America, which always incur a recipient-defined charge in excess of regular call charges. The callers are charged and Telepremium pay you commission from the traffic passed by telecommunication carrier networks to your international premium rate number.
The format of the numbers starts with prefix of the country followed by digits 1,2,3,4,5,6,7,8 or 9. Usually the last 3 digits from which the first starts with 100 refers to range.
IPRN are available for content service providers who will provider their service in more than one country. The service may not be available from every country, even though there is minimal or no cost to the receiving customer, as interchange rates would need to be negotiated for countries to allow origination of calls. The callers are charged and Telepremium pays the service provider commission for the traffic.
