Ireland Porting Process 

  1. Submit your Porting request, with all requirements in place, to
  2. The 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. 
  3. 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.
  4. Twilio’s Carrier Partner reaches out to the Losing Carrier. This can take around one week to complete.
  5. 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 account number or invalid/incomplete range of numbers. 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.
  6. 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.
  7. 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.
