Is a call from 928 a scam?

The area code alone says nothing about the caller. It shows where the number was set up. It does not show who is calling or where they are. The FTC says scammers can make any name or number show up on caller ID. This is called spoofing, and it can make a call look local when it comes from anywhere in the world.
