In order to ensure that users get a quick response, your bot uses multiple phone numbers to communicate. Once a user has started messaging with the system, they will always be contacted by the same phone number. Phone numbers for your institution are purchased randomly but will have an area code that matches your location.
If you'd like to see what phone numbers your bot uses, you can find them in your SMS/Text Messaging Settings page.
If you have questions about these phone numbers, please contact your account manager.
