Can scammers fake a 240 number?

Yes. Caller ID was built without verification, so a caller can display almost any number. Scammers often pick a number matching the area code of the person they are calling — known as neighbour spoofing — because a local-looking call is answered more often. The US industry response, STIR/SHAKEN, lets carriers sign and verify caller ID, but coverage is still incomplete.

Why do I get calls from numbers with my own area code?

Almost always neighbour spoofing: the caller fabricates a number sharing your area code, and sometimes your prefix, so the call looks like it comes from someone nearby. A matching area code is not evidence that the caller is local.

How do I report a spam call from 240?

Report unwanted calls to the FTC at reportfraud.ftc.gov, and add your number to the Do Not Call registry at donotcall.gov. Include the caller ID number even if you believe it was spoofed — regulators use the pattern of reports, not the individual number.

Is +240 the same as area code 240?

No. +240 is the international dialling code for Equatorial Guinea, while 1-240 is a North American area code. The digits match by coincidence, and caller ID frequently omits the plus sign, which is why the two are mistaken for one another.
