- The TelMex web page about new area codes in México
is no longer available.
(Note: Every number in México changed, and the new
numbers are mandatory effective
.)
All landline numbers in Mexico are now of the form
+52 nn xxxx-xxxx
(Mexico City = 55, Guadalajara = 33, Monterrey = 81) or of the form
+52 nnn xxx-xxxx
(all other locations).
Numbers for mobile phones (cellphones) must insert ‘1’ between the country code +52 and the city code; for example, +52 1 55 xxxx-xxxx for a mobile phone from Mexico City.[discontinued in 2019; dial a mobile number the same way as a landline] See the LincMad Mexico 2019 page (español & English) for information about more recent changes to telephone numbers in Mexico. - BellSouth had an excellent page about the South Carolina coastal area code split (803/843) — an exemplary site. It had a map of the area code split, a list of towns affected by the split, and excellent overall detail on the whole split process. (The pages are no longer on the web, since the 803/843 split is “old news,” but BellSouth is to be commended for its excellent work on that project.)
