These companies are sitting on loads and loads of data. It's quite easy for them to match a given name to your SSN and report it to your credit report.
Citi does not ask for SSN and still finds the authorized users SSN and adds it to their credit report.
There are softwares whose sole purpose is to match data such as this.
