Form 4473 Section D — Completing the NICS Section Correctly

Section D of Form 4473 is the dealer's record of the NICS background check — the transaction number, the date, the result, and who conducted the check. Despite being entirely within the dealer's control, Section D is one of the most frequently incomplete sections on Form 4473. The errors here aren't the buyer's responsibility. They're yours.

What Must Be Recorded in Section D

Federal regulations require the following information in Section D for every NICS transaction:

• NTN (NICS Transaction Number) — the unique identifier assigned to the transaction by the NICS system. This must be recorded exactly as provided.
• Date the NICS check was initiated — not the date the form was completed, not the transfer date. The date you called or electronically submitted the check.
• The response received — Proceed, Denied, or Delayed. This must be explicitly recorded, not implied.
• If Delayed, the date of the final response — when NICS provided a Proceed, Deny, or when the three-business-day period expired without a response.
• The name of the person who conducted the check — this is the individual who called or submitted the NICS inquiry, which may be different from the person who initiated the sale.

The Most Common Section D Omissions

The NTN number is left blank — sometimes because the dealer forgot to write it down during the call, sometimes because an electronic system didn't prompt for it. Without the NTN, there is no way to link the Form 4473 to the specific NICS transaction, which defeats the entire purpose of the documentation requirement.

The response type is recorded but the date is missing. Or the date is recorded but without a clear indication of whether the response was Proceed, Denied, or Delayed. Ambiguous entries don't satisfy the requirement.

State Point of Contact Systems

In states that use a state point of contact (POC) system rather than contacting the FBI directly, the documentation requirements are the same — but the transaction identifier may be different from a standard NTN. Know what your state's POC system provides as a transaction reference number and record it in Section D.

NICS Exemptions

Certain transfers are exempt from the NICS check requirement — most commonly transfers between licensed dealers (FFL-to-FFL transfers where the recipient is also an FFL). For exempt transfers, Section D should indicate the exemption — typically by noting the FFL number of the receiving dealer. Leaving Section D blank for an exempt transfer without documenting the exemption reason creates an unexplained gap in the form.

Electronic Systems and Auto-Population

Many FFL management systems auto-populate Section D fields from integrated NICS submissions. If you use such a system, periodically verify that the auto-populated data is accurate and complete. System errors or integration failures can result in blank or incorrect Section D entries that you won't catch unless you review the forms.
