US Patent 11354438 Phone number alias generation

The disclosed systems and techniques enable an enterprise system to store contact phone numbers for users while avoiding storing and managing personal phone numbers for the user. For example, the enterprise system may forward personal phone numbers to an aliasing server configured to (i) generate alias phone numbers based on the personal email addresses and (ii) provide the alias phone numbers to the enterprise system. The aliasing server may operate as a “middle man” that receives phone calls or text messages directed to the alias phone numbers and that forwards the phone calls or text messages to the corresponding personal phone numbers (when appropriate). The enterprise system may store and maintain the alias phone numbers in lieu of storing the personal email addresses.
