where is the telephone area code 469 located
Area codes 214, 469, and 972 The 1990 split was intended as a long-term solution, but within five years 214 was close to exhaustion due to the rapid growth of the Metroplex as well as the popularity of cell phones, fax machines and pagers. Additionally, the entire Metroplex is a single LATA, so several numbers in 817 weren't available for use. To solve this problem, in 1995 all of the old 214 territory outside Dallas and Dallas County was split off as area code 972. Within only two years, however, both 214 and 972 were on the verge of exhaustion. To solve the problem, area code 469 was introduced on July 1, 1999 as an overlay for most of the eastern portion of the Metroplex. At the same time, the 214-972 boundary was "erased," and 972 was converted into an additional overlay for the entire region. The result was three area codes overlaying the same area, with ten-digit dialing required for all calls.
Telephone numbers in Switzerland The Swiss telephone numbering plan implements the ITU-T recommendation E.164 and is designated E.164/2002, based on its last major revision in 2002. It is a closed numbering plan,[1] which means that all telephone numbers, including the area code, have a fixed number of digits. Swiss area codes are officially termed national destination codes (NDC). A complete telephone number consists of ten digits: 0xx xxx xx xx. Two formats are distinguished: three digits for the NDC and seven digits for the subscriber number, and four digits for the NDC and six digits for the subscriber number. However, a few exceptions exist.
