The National Telecommunications Commission of the Philippines has mandated a change to the country's local numbering plan for phone numbers in the 02 area code, which covers Metro Manila and neighboring areas. Starting October 6, 2019, all numbers will transition from 7 to 8 digits in length, with an additional "8" added to the end of the current 10-digit format. This change is designed to support the long-term growth of the Philippines' telecommunications market and is already being implemented by Twilio for its customers using local numbers in this area code. Customers are advised to inform their customers about the change, modify their Twilio applications as necessary, and update their databases to accommodate the new 8-digit format. The change will cause some disruption during the migration period, but Twilio will provide support to help customers through the transition.
