If you get a call from strange number you don't recognize, you may not want to call them back. 

Scamsters from the Caribbean -- where most phone scams originate -- are using autodialers and ringing random numbers in the hopes of running their latest con on you.

They ring your line once and hang up.

You see it as a call from a number you don't recognize and call back.

When you do, they got you.

You're calling a long distance line and being charged a hefty fee for it, sometimes $30 for the call and $9 a minute.

Most of these calls seem to be coming from numbers of Caribbean-based area codes.

It's smart to check out where the calls came from before you dial.

Here are the known suspect area codes: 

473, 809, 876, 284, 268
