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:
“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends’ portraits hang and look thereon;
Ireland’s history in their lineaments trace;
Think where man’s glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (1865–1939)
““And now this is the way in which the history of your former life has reached my ears!” As he said this he held out in his hand the fatal letter.”
—Anthony Trollope (1815–1882)
“I saw the Arab map.
It resembled a mare shuffling on,
dragging its history like saddlebags,
nearing its tomb and the pitch of hell.”
—Adonis [Ali Ahmed Said] (b. 1930)
