Yes, it is possible for your port to complete either before or after the scheduled date. As soon as we have an expected completion date for your number, we’ll send you an email. While we strive to complete porting on the indicated date, the process involves coordination between two carriers to re-route and reconfigure your phone numbers, which can lead to variations in timing.

• Early Completion: In some cases, ports may complete 1-3 days before the specified date. To prepare for this, ensure that your phone numbers, particularly voice and/or messaging URLs, are configured and ready before the porting date. You can do this from the Numbers section of your Twilio project.
• Delayed Completion: Occasionally, the porting date may be postponed. If this happens, we will notify you as soon as possible. To avoid any lapse in coverage, keep your current carrier and phone service until you verify that traffic is appearing in your Twilio logs.

Additionally, phone numbers submitted for porting at the same time may receive different porting dates due to differences in carriers or physical infrastructures. We will keep you updated on all your numbers, and you can track your port requests through the porting requests section of the console.
