Telephone country code 164 is not currently assigned to any country. Country codes are assigned by the International Telecommunication Union (ITU) to each country or region for use in international telephone dialing. The ITU periodically updates and reassigns country codes based on various factors, such as changes in telecommunications infrastructure or geopolitical boundaries. If a country code is not in use, it may be reserved for future assignment or retired from the numbering plan.
