Mexico Porting

The following topics are discussed in this guide. Click a topic to skip directly to this information:

In Mexico we offer porting for the following number types:

  • Geographic (local)
  • Toll-Free (+52800)

Please note that most of International Phone Numbers have VOICE capability only. Only Mobile numbers have VOICE and SMS. Below are instructions for porting Mexican phone numbers into Twilio. 

Once your request is received, we will place your order on your behalf using a legal document called Letter of Authorisation, which states you are giving the gaining operator the authority to act on your behalf with regards to your numbers. The order will be placed with the losing communication provider, for them to validate/accept the port order. 

Mexico Porting Requirements

  • Letter of Authorization (LOA) signed by the authorized user and/or owner of the number(s). Letter of Authorization must be in Spanish. You can use English translation for guidance. Note that the information on your LOA must match the authorized user name and service address provided by your current carrier.

If your number is from a different locality you can reach out to porting@twilio.com to confirm if it is portable.

Mexico Porting process

  1. Submit your Porting request, with all requirements in place, to porting@twilio.comThe number gets approved by Twilio. If everything in Step 1 was done correctly, you can expect Twilio to approve your port request in 24 hours. 
  2. The number is submitted to Twilio’s Carrier Partner. This can take up to 24 hours. Your request is then submitted to your soon-to-be former carrier as a port request. During this time, do not close your account with your carrier and keep your numbers active.
  3. Twilio’s Carrier Partner reaches out to the Losing Carrier. This can take around one week to complete.
  4. Response from the carrier. At this point, your request will either be approved or rejected:
    • Approved: If approved, you will receive a porting date of when your number will be ported to Twilio.
    • Rejected: Rejections can occur for a variety of reasons, such as Incorrect End User Details, Incorrect Site Address, Incorrect number details (Missing DDI range, associated numbers etc). Read more about common reasons for port request rejections here. Additionally, you will likely need to reach out to your losing carrier to find out what’s needed to move forward. Depending on the needs of the carrier, this will add an undetermined amount of time to your porting request.
  5. Twilio reaches out to you with your porting date. Twilio will send you an email of your porting date for when your number will be transferred to Twilio. Once your porting date has passed and you’ve verified the number has transferred to your Twilio project, you can begin using your number. Please configure your number at this time.
  6. Configure your number. It is critical to set up the URL in advance of the port date so that everything is ready for when traffic ports over to Twilio. You can configure the numbers from your Twilio account portal.

We charge a one-time porting fee for Mexico, for more details please reach out to porting@twilio.com.
