The ATF has sent out revised 4473 forms for all FFL’s to begin using. On November 1st, the use of the prior form must discontinue. Contact your local ATF field agent with any questions. A list of ATF offices can be found at https://www.atf.gov/contact/atf-field-divisions or email questions to FIPB@atf.gov
You should have received notice my mail along with a small supply of the revised form for use.
