How to Dial in Mexico – Things Are Changing: 


If you have ever dialed a phone in Mexico, then you likely recall that it was a horrifying experience filled with odd, jumbled, nonsensical digits—especially if you live in Mexico City. Dialing a Mexican phone to the United States can sometimes be as complicated. Well, all that has recently changed. The Mexican government has changed the way that Mexico dials internally and also the way it dials out to other countries like the United States. So WeExpats decided to write an article on how to dial in Mexico. 


How to Dial in Mexico – Why the Change:

On August 3rd, 2019, the Federal Institute of Telecommunications (IFT) rolled out their changes to how to dial in Mexico. Before the system was too convoluted, with prefixes that only worked in certain regions or in certain conditions. Now the numbers that are dialed in Mexico will be the same—even if you are dialing in Mexico from a cellphone or a landline. All numbers will be like in the United States, with 10 digits. All other prefixes are eliminated


According to the IFT, these measures guaranteeing uniform dialing throughout the entire nation and abroad will ensure that Telecommunications Service Providers will simplify their electronic procedures, standardize all dialing procedures, ensure that anyone can contact services regardless where they live in Mexico, and make the management of numerical resources more efficient. In addition, these changes to how to dial in Mexico will make the administration of signaling resources more efficient. 


How to Dial in Mexico – No More Prefixes: 


If you dial often throughout Mexico or to the United States, then hearing that you will no longer be using prefixes when dialing in Mexico might seem like it’s your birthday. It’s true. The following prefixes will be removed from Mexican phones:


  • 01 – Used to dial non-geographic numbers and national long-distance calls; also used in international long distance calls to mobile phones under “calling party pays”
  • 044 – Used to dial national mobile phones in the “calling party pays” mode
  • 045 – Used to dial national long-distance from a landline to a cellphone 


*As some are reporting, it is unclear how removing the prefixes will affect the “calling party pays” mode.

    Not thrilled by Telcel. When I had a desk phone instaled in my home, they required me to get a mast strong enough to hold a huge antenna. which didn’t work well. The local store couldn’t or wouldn’t help, sending me to a Telcel branch in a neighboring state where it was determined I had the wrong antenna, and to go buy another type and install it myself. When I moved, the antenna cable connection to the phone itself broke off. I was told they don’t fix this problem but to have it done by a furniture store or hardware…No go. Finally, after paying for several months of non-service and a cencellation fer, they gave me a new cellphone that would allow calls anywhere in México or the USA….Smell problem, those instruments don’t work in the mountains where i live, apparently only in metropolitan areas. Yes, if I take it with me it seems to be okay for local calls, but I get a recorded that the US number, including my very large bank, cannot be called.

    What about 800 numbers?

    • Raf Bracho

      Alfredo, do you mean American toll free 800 numbers?

  • Martha McCraw

    Yes how do you dial an 800, 866, 877, 833 from Mexico and why do I get a recording saying that if you are calling from Mexico you will be charged because this is not a toll free number

    • Raf Bracho

      Hello Martha,

      Toll-free numbers mean that the company will pay for the bill–not you. However, the company is reluctant to pay for long-distance calls. If you have a Magic Jack or an American number, you can call an 800 number.
