The Western Electric Type 500 telephone becomes available in the United States after announcement in 1949. January 1878: The first commercial North American telephone exchange is opened in New Haven, Connecticut. The first major change was in May 1990, when the London 01 area code was replaced with 071 and 081. Local numbers remained seven digits long. Exchanges in central London used the 071 code. The remaining exchanges now used the 081 code and formed a ring around the 071 area. [34] Although this effectively doubled the available numbers from eight to sixteen million, it was not to be the last change for the capital. Baker, Burton H. (2000), The Gray Matter: The Forgotten Story of the Telephone, Telepress, St. Joseph, Michigan, 2000. ISBN 0-615-11329-X March 1880: National Bell Telephone merges with others to form the American Bell Telephone Company.

The international access code also changed on "PhONEday", from 010 to 00 thus meeting the international call prefix standard set by the International Telecommunication Union (ITU). The Big Number change meant that London returned to a single area code again (as in the old 01 days), with no "inner/outer" split. Existing London numbers acquired the prefixes 7 or 8, but from that point on (020) 7xxx xxxx and (020) 8xxx xxxx numbers were assigned or reused anywhere in the London area covered by the single (city-wide) 020 code. Francis Blake invents a carbon transmitter similar to Edison's that saves the Bell company from extinction. For example, numbers in Barrow-in-Furness already used the ranges starting (0229) 2 and (0229) 5. Millom used the separate 0657 area code, but was already controlled by the Barrow-in-Furness Group Switching Centre. Millom numbers were transferred to the 0229 area code using number ranges beginning (0229) 3 and (0229) 7.
