What does 011[number] do?
011 is the North American exit code. From within the US it does the same job as the plus sign: 011, then the country code, then the local number.
AT&T documents both forms side by side. The difference matters the moment you leave the country, because 011 is only correct while you are on a US network, whereas the plus adapts wherever you are.
Canada, and Caribbean destinations inside the North American numbering plan, are the exception. Those are dialled as 1 then the area code and number, exactly like a domestic call, though they are still billed as international.
Important: International calls are billed per minute on most US plans unless you have an international calling add-on. Check the rate before a long call.
How do I use 011[number]?
- Dial 011.
- Add the country code.
- Add the local number without its leading zero.
- For Canada and most Caribbean destinations, dial 1 plus the area code instead of 011.
Which carriers does this apply to?
