List of Country Calling Codes - History

History

CCITT, the predecessor of the ITU Telecommunication Standardization Sector (ITU-T), developed the first formal list of telephone country codes. This list was included in the 1964 CCITT Blue Book, among other international telecommunication recommendations, which would eventually become ITU-T recommendation E.164.

An earlier system of country codes for European use was mentioned in the 1960 CCITT Red Book. Some of these country codes were retained in the CCITT country code assignments and remain in effect (for example, France +33, United Kingdom +44).

For further details on country code history and development, see History of Country Codes (WTNG).

Famous quotes containing the word history:

    ... all big changes in human history have been arrived at slowly and through many compromises.
    Eleanor Roosevelt (1884–1962)

    The disadvantage of men not knowing the past is that they do not know the present. History is a hill or high point of vantage, from which alone men see the town in which they live or the age in which they are living.
    Gilbert Keith Chesterton (1874–1936)

    The history of his present majesty, is a history of unremitting injuries and usurpations ... all of which have in direct object the establishment of an absolute tyranny over these states. To prove this, let facts be submitted to a candid world, for the truth of which we pledge a faith yet unsullied by falsehood.
    Thomas Jefferson (1743–1826)
