Here is something for the tea partiers among us. Government is sure to get it wrong.
I serve as independent scientific reviewer for grant applications at the National Institutes of Health. For each review panel meeting we get a token "contractor" fee (no option to waive), and to obtain the fee, we need to register with D-U-N-S (Data Universal Numbering System). Here is the link where you can request a DUNS number with grants.gov:

Providing an e-mail address is required, and I used duns.20...@spamgourmet.com - good deal, because this is now my top spammed disposable with over 1700 spams since 2005.
