An international number is calling me: what to do and how to block it
A call from a country code you don't recognize, or from an area code like 876 or 809 that looks domestic but isn't. Here's why these calls happen, whether answering costs money, what never to do, and how to block and report them.

An international number is calling me: what to do and how to block it
Your phone shows a number starting with +44, +234, +91, or another country code you don't recognize. Or a number that looks almost local, with an area code like 876 or 809, rings once and hangs up. You don't know anyone there, so why are they calling? Most unexpected international calls are spam or scams: one-ring callback traps, impostors, or automated campaigns. The safest rule: don't call back numbers you don't recognize, and never share personal information with an unknown caller from abroad.
Why am I getting calls from abroad if I don't know anyone there?
- One-ring ("wangiri") scams. The phone rings once so you'll call back out of curiosity. The number is a premium or international line, and you pay for the call.
- Scam call centers abroad. Many tech support, investment, government impersonation, and prize scams are run from other countries.
- Spoofed numbers. Caller ID can be faked to show any country code.
- Mass dialing. Automated systems call huge lists of numbers to see which ones answer.
- Legitimate reasons: an international company, a relative traveling, a verification service. That's why the key is how you respond, not panic.
The "looks domestic" trap
Many Caribbean countries and territories share the +1 country code with the US and Canada, so their numbers look like regular ten-digit numbers. Area codes such as 876 (Jamaica), 809 (Dominican Republic), 284 (British Virgin Islands), and 473 (Grenada) are frequently used in one-ring and callback scams. Calling them back can be charged as an international call.
Does it cost money to answer an international call?
On a US mobile plan, answering an incoming call from abroad usually doesn't cost extra, unless you're roaming outside the US. The cost comes when you call back: you may be charged international rates, and some numbers are set up to keep you on the line as long as possible. Check your plan's terms with your carrier if you're unsure.
What are the warning signs?
- A single ring and a hang-up, especially at odd hours.
- Repeated calls from different numbers with the same country code or area code.
- A voicemail urging you to call back about a prize, a relative, a delivery, or an "urgent" issue.
- Silence when you answer, or a recording.
- Requests for personal or banking information.
- Someone claiming to be from your bank, a US agency, or a US company while calling from abroad.
What should I do right now?
- Don't call back if you don't recognize the number.
- If you answer, don't confirm your name or personal details, and hang up if anything feels off.
- If they claim to be from a company or agency, hang up and call the official number you look up yourself.
- Search the number in the NoCall spam numbers directory to see whether others have reported it.
How do I block calls from abroad?
- On iPhone: turn on "Silence Unknown Callers" in Settings Phone, and block specific numbers from your recent calls.
- On Android: use "Block numbers" in the Phone app and turn on the caller ID and spam protection option.
- With your carrier: major US carriers offer free spam-blocking apps or features, and some let you block international calls entirely. Ask customer service or check your carrier's app.
- With NoCall: identify spam numbers before you answer.
What if I already called back or gave my details?
- If you called back: check your next bill for international or premium charges. If you see unexpected charges, contact your carrier and dispute them.
- If you gave card or bank details: call your bank using the number on your card, block the card, and dispute charges.
- If you gave personal information: watch for identity theft and use IdentityTheft.gov if needed.
Where do I report it?
- To the FTC at ReportFraud.ftc.gov.
- To the Federal Communications Commission (FCC), which handles complaints about unwanted calls and caller ID spoofing. USAGov explains how to complain about phone scams and robocalls and how to reach the FCC.
- To your carrier, if you were charged for calls you didn't make knowingly.
- In NoCall, in the spam numbers directory.
Frequently asked questions
Can they hack my phone if I answer? Answering a call doesn't give anyone access to your phone. The risk is in what you say or do afterward: calling back, sharing data, or following instructions.
Does the National Do Not Call Registry stop international calls? The registry applies to telemarketers who follow the law; scammers, especially those abroad, ignore it. Blocking tools and not engaging work better.
I'm expecting a call from abroad. How do I tell it apart? If you're expecting a call, answer and verify who's calling. If they ask for money, codes, or personal details, be suspicious anyway.
In short
Most unexpected international calls are spam or scams. Don't call back, don't share details, block the number, and report it. Watch out for area codes that look domestic but belong to other countries. And check and report numbers in the NoCall spam numbers directory.
