If you find this useful please share it!


The “One Ring” and “Missed Call” cell phone scam is becoming more common. According to both the FTC and the FCC, the way this works is that you will get a call from a number that you don’t recognize, starting with what seems to be a U.S.-based area code, such as 809, 876, 649, 268, 473, or 284. The scam is that when you call back to see who it is trying to reach you, you are actually connected to an international “pay per minute” or “pay per call” line, that will run up your phone charges.

As it turns out, there are nearly 200 three-digit country codes that look like U.S.-based three-digit area codes. So far the scams seem to come from 284 (the British Virgin Islands), 268 (Antigua), 473 (Grenada), 876 (Jamaica), 659 (Turks and Caicos Islands), and 809 (the Dominican Republic). You can see a full list of international calling codes here.

According to both the FTC and the FCC, in warnings issued a few months ago, sometimes the scammers will leave voicemail under some pretense, urging you to call back.


Explains the FCC in their One Ring Wireless Scam warning, “If you return the phone call, you may be connected to an international hotline that can charge a fee just for connecting, along with significant per-minute fees if they can keep you on the phone. These charges may show up on your bill as premium services.”

The FTC, in their own warning about the one-ring and missed-call cell phone scam, advises that “If you get a call like this, don’t pick it up and don’t call the number back. There’s no danger in getting the call; the danger is in calling back and racking up a whopping bill.” The FTC adds that if you did fall victim to it, you should “try to resolve the charges with your cell phone carrier. If that doesn’t work, file a complaint with the Federal Trade Commission and the Federal Communications Commission.”

There are several ways to protect yourself against this scam:

  • Don’t return calls from numbers that you don’t recognize. By definition, if they are calling your cell phone, they can leave a message. If it’s important, they will call back, and they will leave a message.
  • If you never make international calls otherwise, ask your carrier to block your line from being able to make international calls.
  • If you get a call from one of these numbers, block it from even showing up in your calls or missed calls. That way you (or someone using your phone) won’t be tempted to return the call.
