Which area codes overlay 983?
983 is part of an overlay complex with 303 and 720. 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.
