Objective: 

To cancel a  port-in request submitted by the customer. 

In order to cancel a phone number port request to Twilio, please follow these steps:

1. Timing: You can cancel a port request anytime before the port date is scheduled during the porting process to porting@twilio.com or respond in the same original submitted request and clearly indicate which porting phone numbers you wish to cancel.
2. Carrier Coordination: Once we receive your cancellation request, we will promptly check with the underlying carriers to determine if the port request can be canceled.
3. Notification to Original Carrier: If you decide to cancel, inform your original carrier to ensure they do not discontinue service on the phone number.
4. Fees and Risks: We will do our best to minimize any fees and risks associated with the cancellation. Any fees incurred will be passed through directly.

Important: Once a port date is scheduled, cancellation becomes more challenging and may incur costs or service disruptions. We do not prefer to cancel the port request within 48 hours of the port date. In such cases, we suggest porting the number first to Twilio and then submit a port-out request to take the number back to the previous carrier. 

If you decide to proceed with the port but would like to take the number back to your original carrier post the number ported to us, you can open a port request with your desired/previous carrier to port the number away from Twilio, and for the port-out information, you can reach out to us at porting@twilio.com.  For more information, please see How do I port my phone numbers away from Twilio?
