I just received a notification in the mail today that Centurylink, the incumbent telephone service provider for the Las Vegas area, will require the area code to be dialed for all calls starting May 3, 2014. This is being done because they are out of 702 numbers. Starting May 3 they will start handing out 725 numbers for new installations and new cell phone accounts. The new area code will service the same area that 702 has been servicing, and 702 numbers will continue to work. You'll just need to dial the area code, even when you call another 702 number. Needless to say, if you get a new cell phone it's going to have an area code 725 number.
