The rate center belongs to the Indianapolis-Carmel-Greenwood, IN Metropolitan Statistical Area. Routing-wise it sits in LATA 336.
Multiple area codes over one rate center (317/463) is the overlay pattern: same geography, different first three digits.
With only 4 prefixes, Marietta sits at the small end of Indiana'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.
