Anonymous SMS API
Use TeleSign’s Anonymous SMS API to create anonymous, limited-duration SMS communication sessions between two end users without disclosing their phone numbers. Masking phone numbers adds privacy, identity protection, and ensures conversations and transactions remain on-platform. With the Anonymous SMS API, you do not have to buy phone numbers to mask your numbers (though you may do so if you wish), instead numbers are drawn from an existing pool, making it easy to use and set up.
