SMS content and retention
SMS content consists of the alert types you enable in your Notification Preferences (e.g., bid exceeds your max, auction ending soon, valuation changes) and the one-time sign-in codes you request. We do not send marketing SMS.
One-time sign-in codes. If you turn on text message codes for two-step verification, we text a one-time code to the mobile number you confirmed in account Settings, and only when you ask for one: when you set up the method, when you choose a texted code while signing in, and when you confirm a change to your two-step settings. We send them through Twilio Verify, which creates, texts and checks each code, so your number and the code go to Twilio for that purpose only. Sign-in codes are security messages. They are not alerts and not marketing, and they do not depend on the SMS consent described above. We send no more than one every 30 seconds and no more than 10 in any 24 hours per account, and each code expires after 10 minutes. Message and data rates may apply. To stop receiving them, remove the text message method under Settings → Security. Replying STOP to an SMS alert, or revoking SMS consent, does not remove it.
SMS consent records are retained for at least four (4) years after consent revocation to defend against potential TCPA disputes, as is standard industry practice.
