Search Area Codes

Yesterday, I went to the town and I met Cecil (my friend's name) at the internet shop of Auntie Cita. She asked me if I know what is the area code of California because she will going to send a birthday card to her niece who is working there. I told her that there's this website Search Area Codes that will going to find her the different area codes in any state of America. And I told her that since we are there in the internet shop why not visit their site. So, if ever you have problems about area codes just visit their site...:-)
