"Why is there a line on my phone bill for a country I have never visited?" A relative asked me that once, holding the bill out as if it might explain itself. The numbers she had called looked like any other American number. They were not, and the phone network did nothing to make the difference obvious. This page is the procedure I wish I had handed her: how to place a call to Canada or the Caribbean knowing what it may cost, and what to do when one of those codes shows up on your screen without being asked.
Why the dialing hides the cost
Canada, the US territories and a number of Caribbean countries share the North American numbering plan with the United States. A Jamaican number is +1 876 followed by seven digits, the same shape as +1 614 followed by seven digits in Columbus, and nothing on the keypad separates them. The background on why the plan blurs those lines is in why numbers start with +1. Dialing is domestic everywhere inside the plan. Pricing is set by agreements between carriers and national regulators, and it has nothing to do with the digits you press. The steps below put a check in the gap that the dialing leaves.
Place a call without a surprise
- Find the area code. Take the three digits right after the 1, or after the +1 in a saved contact. On a contact card they sit at the front of the number. What you will see: three digits such as 416, 876 or 787, and nothing else on screen tells you where they belong.
- Sort the code into one of three groups. The prefix reader does this in one step: type the number and read the Country line of the result. Without it, the codes people ask about most fall like this.
- Canada: 416 (Toronto), 604 (Vancouver), 514 (Montreal).
- US territories, treated as domestic on US plans: 787 and 939 (Puerto Rico), 340 (US Virgin Islands).
- Independent Caribbean countries: 876 (Jamaica), 242 (The Bahamas), 246 (Barbados), 809, 829 and 849 (Dominican Republic), 868 (Trinidad and Tobago), 784 (St. Vincent and the Grenadines).
- Check what your plan says about that group. Open the plan page or your latest bill and search it for the words "Canada" and "Mexico". Many US mobile plans treat Canada like home, some do not, and prepaid or older landline plans often charge per minute. I cannot tell you which one you have, so I will not guess. Roaming is a separate matter: using your US phone while you are physically in Canada can carry its own charges or an included allowance, while the dialing format stays the same. What you will see: either a line saying Canada is included, or a per-minute international rate.
- For an independent country, look at the international rate before you dial. Calls to territories are ordinary domestic calls. Calls to independent nations are international in every way except the dial pad, and a carrier may bill them that way. If you cannot find the rate, do not place a long call until you can. What you will see: a rate table for the country by name.
- Dial 1 and ten digits, or tap the contact. A contact saved as plus, 1 and ten digits works from a phone anywhere. What you will see: the call connects like any domestic call, with no prompt and no warning. That silence is the reason steps 2 to 4 exist.
- Check the usage detail afterwards. Most carriers show itemised calls online. Look for the number and the minutes, and compare with the rate you found. If the first call to a place goes through without a bill surprise, you now know how your plan treats it.
Texts follow the same logic as calls: the dialing is domestic, and whether a message to an independent country is priced as an international text depends on the plan, so the plan page is the place to look. If you are doing this on behalf of someone who gets nervous about phone bills, an older parent for instance, ask them to read you the three digits before they dial. Ten seconds at the kitchen table builds a habit of checking first, and a habit does more good than any filter.
When a missed call arrives from one of these codes
The one-ring scam, sometimes called wangiri after a Japanese phrase meaning "one ring and cut", works on exactly the gap described above. Your phone rings once, long enough to leave a missed call and not long enough to answer. The number looks almost local, and curiosity does the rest. If you call back, you may be connected to a line that charges by the minute, and whoever set it up collects a share of the fee. The FTC has warned consumers about this kind of call in general terms, at consumer.ftc.gov, and I would rather not guess at how common it is.
- Do not call back. A missed call from a code you cannot place, at an odd hour, with no voicemail, is the typical shape of it. A real caller will leave a message or send a text.
- Look up the code. Run the number through the reader. What you will see: a country name. If it is a Caribbean or foreign one, a return call may be billed at international rates.
- Decide whether to block. On an iPhone, open the call in Recents, tap the i beside it and choose Block this Caller. On Android with the Google Phone app, open Phone, then the three-dot menu, then Settings, then Blocked numbers. What you will see: the number added to a blocked list, with future calls from it silenced. Menu names shift a little between versions, so treat these as the general path.
- Cut down the rest. On an iPhone, Settings > Phone > Silence Unknown Callers sends numbers that are not in your contacts to voicemail. On Android, look under Caller ID and spam in the same Phone settings. Both are blunt: a legitimate caller who is not in your contacts will land in voicemail too.
- Ask your carrier about an international block. Some carriers can switch off international calling on the line, which is a direct fix for people who never place such calls. Use the carrier's official customer service number to ask.
If something goes wrong
The call will not connect
A plain format mistake is the usual cause. Check that you dialed 1 and ten digits, or tapped a contact saved in the plus form, and that your plan allows calls to that country. A message from your own carrier saying the number is not in service at the very start of the call usually points to a format error rather than a dead line.
A line on the bill that I do not recognise
Look at the itemised detail for the date, time and number. If a charge is wrong, call the carrier using the number printed on its own bill, explain the circumstances and ask what it can do. Write down who you spoke to and when. Charges for these calls can sometimes be disputed, but I make no promise, because it depends on the carrier and the case.
I already called back
Do not panic and do not assume the worst. Check your next bill for lines you do not know, and report the number at reportfraud.ftc.gov. A related kind of charge, where the prefix itself is built to bill the caller, is covered in 900 numbers and pay-per-call prefixes.
Will the Do Not Call Registry stop these calls?
No. The registry (donotcall.gov or 1-888-382-1222) covers legitimate telemarketers, and scam operators do not follow it. Treat it as a tool for sales calls, not for this.
