If you are the proud owner of a landline in New Hampshire, or you use one at work, I'm sure you have enjoyed only having to dial 7 digits for in state calls up until this point. I hate to be the bearer of bad news, but according to the Concord Monitor, pretty soon we will all have to start dialing 10-digits for in state calls. If your 603 pride runs deep and you are nervous about having to change your area code, don't you fret! The article explains we are not getting another area code anytime soon. The 603 is here to stay and will likely remain our only area code in the state for at least another decade.
