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.
999 (emergency telephone number) The pan-European 112 code was introduced in the UK in April 1995[16] with little publicity. It connects to existing 999 circuits. The GSM standard mandates that the user of a GSM phone can dial 112 without unlocking the keypad, a feature that can save time in emergencies but that also causes some accidental calls. All mobile telephones will make emergency calls with the keypad locked. Originally a valid SIM card was not required to make a 999/112 emergency call in the UK. However, as a result of high numbers of untraceable hoax calls being made, this feature is now blocked by all UK networks. Most UK mobile telephone handsets will dial 999/112 without a SIM inserted (or with a locked/invalid SIM), but the call will not be connected. Following the blocking of SIM-less calls, in 2009 the UK networks introduced emergency call roaming. This allows a user with a valid SIM of a UK network to make emergency calls on any network for which they have coverage.
