Here's the 411 on the 657 in the 714
Telephoning a neighbor will soon become a bit more complicated for Orange County residents living in the 714 area code. Starting Saturday, the new 657 area code will go live and will share the same northern O.C. turf covered by the 714. Current 714 customers will keep their numbers but they will have to dial 1-714 even if they are calling next door. You can get away without punching those extra digits until Aug. 23, when the break-in period ends.
Don't forget that you will also probably need to re-program your phones, fax machines and alarm systems, reminds the OC Register.
