Question 5

Is a call from area code 551 a scam?

Accepted Answer

A 551 number is geographically tied to New Jersey, 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.

Question 6

Is 551 a country code?

Accepted Answer

No. 551 is a US area code (a domestic 3-digit code), not a country code. The country (calling) code for the United States is +1. So a full 551 number written for international dialing looks like +1 551 followed by the 7-digit local number.
