Form 4473 Section B — Common Mistakes and How to Avoid Them

Section B of ATF Form 4473 seems straightforward — it's where the buyer fills in their name, address, date of birth, and identification information. But despite its apparent simplicity, Section B generates a disproportionate number of compliance violations during ATF inspections. The reason isn't that the questions are hard to understand. It's that dealers often treat Section B as the buyer's responsibility and don't review it carefully before completing the transfer.

What Section B Covers

Section B covers Questions 1 through 9 on the current Form 4473. This includes the transferee's full legal name, current residential address, place of birth, date of birth, Social Security Number (optional but recommended), height, weight, sex, and ethnicity/race. It also includes the certification that the buyer is the actual transferee and not acquiring the firearm on behalf of someone else — the anti-straw purchase language that sits at the top of Section B.

The Most Common Section B Errors

Incomplete Address

The buyer writes their city and state but omits the street address, or writes a P.O. Box when a residential address is required. The ATF requires a current residential address. A P.O. Box alone is not acceptable. If a buyer lives in a rural area with no street address, they should describe their physical location.

Date of Birth Format Errors

This sounds trivial but shows up constantly. The buyer writes the month as a word ("January") instead of a number, or reverses the month and day. The form requires MM/DD/YYYY format. When an IOI sees inconsistent date formats across hundreds of forms, it signals that the dealer isn't reviewing the paperwork before transferring.

Missing or Illegible Handwriting

The buyer's handwriting is unreadable, or fields are partially filled in and then crossed out without initials. The ATF needs to be able to read every entry. If a buyer makes an error, the correction must be made by the buyer — not the dealer — and initialed and dated. White-out is never acceptable on a 4473.

Name Doesn't Match ID

The buyer uses a nickname or shortened version of their legal name that doesn't match their government-issued ID. The name on the 4473 must match the name on the identification document used to verify identity. If a buyer goes by "Bill" but their ID says "William," the form should say "William."

Straw Purchase Certification Left Blank

The certification at the top of Section B — confirming the buyer is the actual transferee — is sometimes left blank or not fully completed. This is a significant violation because it's the legal foundation of the Form 4473. Without a completed certification, the form doesn't establish that the transfer wasn't a straw purchase.

The Section B Review Checklist

Before every transfer, run through this mental checklist for Section B:

• Full legal name matches government-issued ID exactly
• Complete residential street address — no P.O. Boxes alone
• Date of birth in MM/DD/YYYY format
• All required fields completed — no blanks
• Straw purchase certification fully completed
• Any corrections initialed and dated by the buyer
• Handwriting is legible — if you can't read it, the ATF can't either

What Happens When Section B Has Errors

Section B errors are almost always classified as reporting violations. A single error on an otherwise complete form is unlikely to trigger anything beyond a notation in the inspection report. But if an IOI finds the same Section B error pattern across dozens of forms — say, addresses routinely missing the ZIP code — that pattern becomes evidence of systemic non-compliance rather than isolated mistakes. Patterns are what escalate compliance issues from warnings to conferences to revocation proceedings.
