975 overlay codes and dialing
The 975 territory is covered by an overlay of 2 area codes: 816, 975. All of them serve the same geographic area, and the original code is 816. Because more than one code covers the same ground, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes.

Is 975 a scam or spam risk?
975 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 975 number on your screen is no guarantee the caller is in Kansas City, MO or trustworthy.
