International code 388 3 was assigned by the International Telecommunication Union (ITU) to 24 European countries. The decision to assign ‘3883’ was made in March 2000.
The general requirements of the Recommendation of the ITU on the international public telecommunication numbering plan, known as E.164, apply to ETNS Numbers in the same way as they apply to other numbers that are internationally diallable.
An additional ITU Recommendation, E.164.3, contains more requirements that are more specific to the ETNS. |
