Twilio must verify to carriers that we have permission to run traffic over a short code we do not own. Therefore, if you choose to maintain your own short code lease, you will need to provide us with your short code’s lease receipts on an ongoing basis. Not providing those leases can cause an interruption in your short code’s service.
To obtain your current lease receipt, log into your CSCA account and download a copy of your current receipt from the “My CSCs” section of their account portal. If you are having trouble accessing that account, please contact Twilio support for further assistance.
If you are interested in transferring management of your short code lease to Twilio (which we recommend), please see Transferring a short code lease into Twilio's iconectiv/CSCA account .
