How long does it take to port a number to Twilio?
Due to the carrier coordination involved, the porting process takes between two and four weeks from when we receive the required documentation from you, assuming there are no rejections. The amount of time varies depending on the carriers involved.
Due to their complexity, bulk ports typically take between six and eight weeks to complete.
If a rejection occurs during the porting process, an additional two to four weeks may be added from the time that the rejection is resolved.
