This topic was here two years ago. I'll rehash what I have in
Maryland: each geographic area code (301 and 410) has an overlay area
code (240 and 443 respectively) mixed in. The overlays put an end to
7D local calls (which now have to be dialed with 10D instead, although
1+10D will also work). And it was noted that 240 and 443 were in use
in Washington DC area suburbs (area 301) as PREFIXES, so the nearby
equipment could NOT jump to intercept when someone goofed and tried
dialing a local call as 240-xxxx or 443-xxxx.

Also recall that in the Chicago area, 847 is one of the area codes and
is a prefix in what's now 773 area in city of Chicago, and since 7D
was being allowed in the Chicago area, you had this scenario if you
were in what's now 773 area: dial 1 847 abc defg for a local call to
area code 847 or your call will complete to 847 abcd.
