When starting your Mexico genealogy research, it's often necessary to find family in Mexico such as a parent, brother or cousin. You may have a phone number for this relative, but now the number doesn't work. But before you throw that number away, you may be missing one small piece of information.

Back in 2001, Telmex, Mexico's national telephone company, made huge changes in its area code system. You can click here to read more, but the bottom line is that you may have a good telephone number if you put it with the new area code.
