Lady Gatekeeper recently received a few annoying calls on her cell phone. No one ever answered from the other end of the line. Therefore, she found it necessary to Find Area Codes and see where this call was coming from. The information was much appreciated. And, by the way, it is quite confusing to remember which area code is actually yours when you live in CA. We keep adding new ones. Nice to have a list to show us which code belongs to what area. California has the longest list of area codes in the US. Ah, keep it simple Cal.
