When I lived in Gadsden, Alabama in the late sixties, they had a five digit plan. The two exchanges there are 546 and 547. You could dial
68820 (which was our telephone number at home). Or 72550 (one I made up just now) and actually reach 546-8820 and 547-2550.
I sincerely doubt that that plan is still in place (I just don't know either way).
There was also a 543 exchange that was a local call to our area. But it did not work to dial three and the last four digits. I don't particularly know why.
