Is a 1-866 number toll-free from Mexico?

Answer 1

1-866 is a toll-free prefix in the United States. You may be able to dial it from Mexico by dialing it as if it were an ordinary geographic number in the US. Although a few US toll-free numbers have special arrangements to make the numbers toll-free also from Mexico (dialing 00 1 8xx etc.), most do not. If the call does go through, you will most likely pay the international call charges for a call to the U.S.

Answer 2

You can try dialing the number as if it were an ordinary geographic number in Canada; i.e., 00 1 866 xxx xxxx. A few North American toll-free numbers have special arrangements to also be toll-free from Mexico, but in most cases you will pay the international toll rate if the call goes through. If the call fails, your best bet is to look on the web for a geographic (non-toll-free) number for the company you are trying to contact.

Answer 3

In the US, any 1-866 number is toll-free, and a few of them route to people or companies in Mexico. Mexico's area code 866, however, is an ordinary geographic area code for part of the state of Coahuila, including Monclova and Castaños. Landline numbers in this part of Coahuila begin with +52 866; mobile phone numbers from this part of Coahuila begin with +52 1 866; in either case, the remainder of the number is a further 7 digits. Mexican area code 866 is not toll-free from Mexico or from the United States. Toll-free codes in North America are +1 800, +1 888, +1 877, +1 866, +1 855, and +1 844, with +1 833 and +1 822 reserved for future toll-free use.
