If you go into your License Manager page,
https://wireless2.fcc.gov/UlsEntry/licManager/login.jsp
You can request a paper copy.
Under "Paper Authorization Preferences, it'll give you a Yes/No option:
By selecting Yes, you will continue to receive paper authorizations printed and mailed by the FCC. By selecting No, you will not receive authorizations printed and mailed from the FCC. This preference will affect all granted authorizations on this FRN.
I believe it defaults to "no" unless you are getting a new license.
