If a licensee notices an error on the ATF Form 4473 after the transfer, what is the procedure to record the correct information?

If the licensee or the buyer/transferee discovers that an ATF Form 4473 is incomplete or improperly completed after the firearm(s) has been transferred, the licensee should photocopy the inaccurate form and make any necessary additions or revisions to the photocopy. The buyer/transferee should only make changes to Sections A and C. The licensee should only make changes to Sections B and D. Whoever made the changes should initial and date the changes. The corrected photocopy should be attached to the original ATF Form 4473 and retained as part of the licensee’s permanent records.
