First off, the phone system here in Maztalan just changed, so a lot of phone numbers won't work the same way any more. For instance: A phone number that was written like this:

89-05-50

now needs a 9 in front, to make it a 7-digit number. So,

89-05-50

becomes

989-0550

Got that? That's for local calls.

The rest is pretty simple: Mazatlan's area code is 669. When calling long distance from inside Mexico, dial this first. For instance:

669-989-0550

Mexico's Country Code is 52. When calling from outside the Mexico, you need to dial this first, then the area code, then the number. Like so:

52-669-989-0550
