How does Twilio bill for short codes?
Twilio will charge your short code payment to the primary credit card on file in your account, regardless of your Twilio account balance.
Short code payments cover the cost of your short code lease, carrier fees, and the work Twilio does to get the short code up and running. Short codes are billed either quarterly (every 12 weeks) or annually. Your first short code payment is due before we submit your application to the carriers for approval. Your second short code payment will be collected two weeks before your lease renewal date, to guarantee that we have successfully received your payment before we renew your short code with the central registry.
You will be billed for your short code from the beginning of the carrier approval process onward. If you choose quarterly billing, your second billing date will be 10 weeks into the first 12 week service period. You’re still getting all the time you’ve paid for, and you will then be billed every 12 weeks thereafter. Because carrier approval may take 12 – 16 weeks (and sometimes longer), it is possible that your short code may not be fully live before you are billed a second time. You are required to pay for your short code throughout the approval process, even if approval takes longer than expected.
Note: the two week period between your short code billing date with Twilio and your short code’s lease renewal date is not a grace period. If your payments are repeatedly late, your Customer Success Manager will contact you to discuss transitioning to a long code instead.
