Determine if you will incur long distance charges With so many area codes available, sometimes it can get confusing deciding if a phone call will be considered local or not. You will need to know the following phone parts in order to use this tool:

• Area Code or NPA – 1st three digits

• Prefix or NNX – 2nd three digits

Enter the NPA and NNX you’re calling from, plus the NPA and NNX you’re calling to and you will be able to determine if your call is local*.
