I'm old enough to remember when East Texas switched from a 214 area code to 903. However, I didn't know until a couple of days ago that East Texas has a second area code.
A change that the FCC approved last year will bring a change to dialing in several Texas area codes starting in October, and although it won't interrupt most of our dialing routines, you might want to let your Grandma in Waco know what's up.
