ITPCS

• abstract: 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.
