Sec 3512 ab

(a) Notwithstanding any other provision of law, no person shall be subject to any penalty for failing to comply with a collection of information that is subject to this chapter if-- (1) the collection of information does not display a valid control number assigned by the Director in accordance with this chapter; or (2) the agency fails to inform the person who is to respond to the collection of information that such person is not required to respond to the collection of information unless it displays a valid control number. (b) The protection provided by this section may be raised in the form of a complete defense, bar, or otherwise at any time during the agency administrative process or judicial action applicable thereto.;

IANAL, but I intend to fill mine out citing the PRA, and not in a fraudulent manner.
