Is a call from area code 310 a scam?
A 310 number is geographically tied to California, but caller ID can be spoofed, so the displayed area code does not prove where a caller really is. If you did not expect the call, do not share personal information and consider looking the number up.
Is 310 a country code?
No. 310 is a US area code (a domestic 3-digit code), not a country code. The country (calling) code for the United States is +1, shared across the North American Numbering Plan. So a full 310 number written for international dialing looks like +1 310 followed by the 7-digit local number.
