The first sign of trouble appears when the dealer questions the buyer’s eligibility. Common mistakes include marking the wrong box for “Any prior convictions,” writing illegible handwriting, or omitting the purchaser’s middle initial. These errors trigger an automatic review by the ATF, delaying the transfer and sometimes resulting in a denial. Because the form is a legal record, every blank and abbreviation must meet exact standards.
A second symptom shows up in the paperwork trail: the dealer receives a “Form Incomplete” notice weeks later, forcing the buyer to start over. This usually stems from unfamiliarity with the required supporting documents, such as a government‑issued photo ID and, for certain buyers, a residency proof. When those attachments are absent or scanned poorly, the ATF flags the submission, and the entire transaction stalls.
