27 CFR 478.102 - Sales or deliveries of firearms on and after November 30, 1998.
(a) Background check. Except as provided in paragraph (d) of this section, a licensed importer, licensed manufacturer, or licensed dealer (the licensee) shall not sell, deliver, or transfer a firearm to any other person who is not licensed under this part unless the licensee meets the following requirements:
(1) Before the completion of the transfer, the licensee has contacted NICS;
(i) NICS informs the licensee that it has no information that receipt of the firearm by the transferee would be in violation of Federal or State law and provides the licensee with a unique identification number; or
(ii) Three business days (meaning days on which State offices are open) have elapsed from the date the licensee contacted NICS and NICS has not notified the licensee that receipt of the firearm by the transferee would be in violation of law; and
(3) The licensee verifies the identity of the transferee by examining the identification document presented in accordance with the provisions of § 478.124(c).
(b) Transaction number. In any transaction for which a licensee receives a transaction number from NICS (which shall include either a NICS transaction number or, in States where the State is recognized as a point of contact for NICS checks, a State transaction number), such number shall be recorded on a firearms transaction record, Form 4473, which shall be retained in the records of the licensee in accordance with the provisions of § 478.129. This applies regardless of whether the transaction is approved or denied by NICS, and regardless of whether the firearm is actually transferred.
(c) Time limitation on NICS checks. A NICS check conducted in accordance with paragraph (a) of this section may be relied upon by the licensee only for use in a single transaction, and for a period not to exceed 30 calendar days from the date that NICS was initially contacted. If the transaction is not completed within the 30-day period, the licensee shall initiate a new NICS check prior to completion of the transfer.
(d) Exceptions to NICS check. The provisions of paragraph (a) of this section shall not apply if -
(1) The transferee has presented to the licensee a valid permit or license that -
(i) Allows the transferee to possess, acquire, or carry a firearm;
(ii) Was issued not more than 5 years earlier by the State in which the transfer is to take place; and
(iii) The law of the State provides that such a permit or license is to be issued only after an authorized government official has verified that the information available to such official does not indicate that possession of a firearm by the transferee would be in violation of Federal, State, or local law: Provided, That on and after November 30, 1998, the information available to such official includes the NICS;
(e) The document referred to in paragraph (d)(1) of this section (or a copy thereof) shall be retained or the required information from the document shall be recorded on the firearms transaction record in accordance with the provisions of § 478.131.
