Why is the map approximate?
Telephone area codes are assigned through exchanges and overlay complexes, not as a single official street-level polygon. This map centers a known city associated with the code when available; otherwise it uses the jurisdiction center. It must not be used to locate a specific caller or phone.

What 870 tells you—and what it cannot
- FACT
Numbering-plan assignment
870 is assigned to Arkansas under the NANP snapshot.
- CONTEXT
Overlays and time zone
Its listed overlay peers are 327. Time-zone labels describe the service region, not a caller's current clock.
- LIMIT
Not a reverse-phone lookup
The code alone cannot identify a subscriber, prove a caller's identity, or show where a mobile phone is now.
