Area Code 909
Area codes 909 and 840 are telephone area codes in the North American Numbering Plan (NANP) for the far-eastern part of Los Angeles County and southwestern San Bernardino County in the U.S. state of California. Area code 909 was split from area code 714 on November 14, 1992. By August 1993, dialing of the area code became mandatory. Western Riverside County was split off from 909 into area code 951 on July 17, 2004. 909 still covers small portions of Corona, Riverside, Moreno Valley, and the entire city of Calimesa which are in Riverside County. Originally on the same date that 951 was split from 909, the geographic area retaining the 909 area code was to be overlaid by a new area code 752. However, lawsuits filed by the wireless industry in order to prevent California (and other states) from creating wireless-only area codes (after the creation of area code 917 in New York City), which would have identified all customers with certain area codes as being wireless, put all ove ...

Area Code
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks. For public numbering systems, geographic location typically plays a role in the sequence of numbers assigned to each telephone subscriber. Many numbering plan administrators subdivide their territory of service into geographic regions designated by a prefix, often called an area code or city code, which is a set of digits forming the most-significant part of the dialing sequence to reach a telephone subscriber. Numbering plans may follow a variety of design strategies which have often arisen from the historical evolution of individu ...

Interchangeable NPA Codes
In the North American Numbering Plan (NANP), interchangeable NPA and central office codes constituted a change in numbering plan design and policy, to mitigate exhaustion of the numbering resources of the ten-digit telephone numbers used in the closed numbering plan of the NANP. Interchangeable NPA and central office codes are codes that permit any of the ten numerals in the middle position of the area code and the central office code, which both are three-digit numbers.AT&T Network Planning Division, ''Notes on the Network'', Section 2 (1980) This change in numbering format was implemented first for central office codes by 1973, which eliminated the restriction in the middle digit (''2'' to ''9'') to also permit ''0'' and ''1''. The middle position of the area code could only be ''0'' and ''1''. In 1995, this restriction for area codes was lifted as well, creating interchangeable NPA codes. History and background The ten-digit telephone numbers of the NANP consist of a three-digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Prior to November 2, 1991; this region had been part of area code 213. On that date, most of the western and southern portions of the old 213 region became area code 310. On January 25, 1997, the southern portion of the old 310 territory split again to become the 562 area code. 562 was originally meant to be an overlay code exclusively for cellular telephones and pagers for existing 310 area code customers in late 1995. However, the overlay (and all others in CA since 2008) was cancelled after cellular companies sued the California Public Utilities Commission to prevent a repeat of a similar split in New York City, where all 212 & 718 mobile customers were changed over to a new 917 NPA.
