New area code in effect
Callers will have time to get used to new 575 area code
Santa Fe—The new 575 area code has gone into effect. Most callers in New Mexico will have a 12 month “permissive dialing” period to become accustomed to using the new 575 area code, under the area code implementation plan adopted by the New Mexico Public Regulation Commission today. However, some credit union employees in New Mexico report that callers must use the new area code to contact them.
Under the 27-month 575 area code implementation plan, the network preparation and customer education periods will be concurrent and begin immediately; the permissive dialing period begins October 7, 2007; and the recorded announcement/mandatory dialing period begins October 5, 2008 and ends on January 11, 2009. During the permissive dialing period, callers can use either the 505 area code, or the 575 area code, when calling into the locations in the state that have been assigned the new 575 area code.
During the recorded announcement/mandatory dialing period, all calls into the new area code area must be dialed using the 575, and calls which are made with the wrong area code will get a special recorded message advising the caller to redial using “575.” After the end of the recorded announcement period, telephone companies will be able to assign the same seven-digit telephone numbers in both area codes, and so calls without the proper area code may be connected to an unintended party. If the mis-dialed call
is not connected to another line, the caller will get a generic “the call could not be completed as dialed” message.
