What cities use the 645 area code?

Miami accounts for the largest share of 645 prefixes, with Hialeah and Miami Beach next. A local number in any of them reads as local to everyone else on the list, because they all dial on 645.
Which area codes overlay 645?
645 is part of an overlay complex with 305 and 786. An overlay puts more than one area code over the same geography instead of splitting the region in two, so existing numbers keep their code and new ones get the added code. Two neighbours on the same street can hold different area codes. That is why ten-digit dialling is required here: you cannot assume a local call shares your area code.
