If you’ve decided you no longer want your Twilio short code, please contact us at firstname.lastname@example.org. We will promptly follow up with you once we receive your request, and ask you to fill out a brief form.
As a reminder, please understand that once you cancel your short code the short code is no longer usable. If you ever decide that you would like to reactivate a cancelled short code in the future, we will first need to confirm that the short code is still available (it may not be), then we’ll need you to complete a new application, after which we can restart the full, multi-week provisioning process with carriers. For this reason, we suggest that you only cancel your short code if you have no future plans of ever using the code.
