Multiple area codes over one rate center (410/667) is the overlay pattern: same geography, different first three digits.
With only 3 prefixes, Millington sits at the small end of Maryland's rate centers — a handful of carrier blocks cover the whole locality, and a number from here is a fairly strong locality signal (before porting is considered).
Treat this data as geography of the number, not of the caller: porting, VoIP and caller-ID spoofing all detach the two. When a call matters, hang up and call back through an official number.
