ITPCS
From Wikipedia, the free encyclopedia
International Telecommunications Personal Correspondence Service (ITPCS) is an obscure ITU proposal regarding the allocation of country code +991 for use in some form of individual-based international numbering plan. It may have been intended as a space for ENUM trials, as the ITU allocated the range +991 001 to Neustar for use in an ENUM trial in 2002. However, the most recent approved ENUM trial, with Telesoft's Sentiro, was allocated space in the UPT range (country code +878). No other allocations have been reported in the +991 space.
