Updated Mexico Dial Plan Changes Effective August 3rd, 2019

Update August 15, 2019:

  • All existing Mexico dial-plans as of 8-15-19 have been updated and no further action is required
  • All new customers or additional account add-ons to existing customers will still need to contact Support to push the correct dial plan from ops-tools

A permanent fix is being developed by SMP Engineering team at this time. There is no ETA on when permanent fix will go into production. See JIRA SMP-4602 for additional permanent fix status.

 

Mexico dial-plan change summary: Starting on August 3rd, 2019 a new standard 10-digit dialing plan will be implemented in Mexico. This change in dialing format is not specific to 8x8, as it is being implemented by the Federal Telecommunications Institute of Mexico (FTIM).  This change does not impact your service with 8x8 in any way provided users comply with the dialing changes outlined below.

  • All phone numbers will be dialed through 10-digit dial plan
  • Area Codes must be used when dialing to a seven or eight-digit phone numbers
  • The ‘01’ prefix used on Long Distance, 800 and 900 numbers is no longer required
