If you discovered a firearm was missing, could you find its exact serial number without the original box? Could you tell an officer the model without guessing between two versions that look almost identical?
A personal firearm record gives you those details in one place. You can start with a printed form or a password-protected file. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) provides a Personal Firearms Record form that private owners can use. The agency recommends keeping the completed record in a secure location separate from the firearm. atf.gov
Give Each Firearm Its Own Entry
Start with one entry per firearm, even if you own several of the same model. The model tells you which product it is. The serial number identifies the individual item. Keeping those details on the same line makes it easier to answer questions if one goes missing. The ATF form also includes space for details such as caliber or gauge and acquisition information. atf.gov
| Field | What to record |
|---|---|
| Manufacturer or importer | The name as it appears on your records |
| Model | The exact model name or number |
| Serial number | The full sequence, including letters and any leading zeros |
| Caliber or gauge | The designation listed in your records |
| Acquisition details | Date and seller information, if available |
| Supporting documents | A receipt or other record you can locate quickly |
Check entries against reliable documents where available. If a receipt shows a product code and a serial number, put each in the correct field. Take a second look at characters that are easy to confuse, such as the letter O and the number zero. When you can’t confirm a detail, mark it unverified so you know to follow up.
Make Supporting Documents Easy to Find
A receipt is most useful when you can connect it to a specific entry. If you scan receipts, give the files descriptive names and put them in the same private folder as the inventory. If you prefer paper, number each entry and use the same number on the sleeve holding its supporting documents.
Suppose you own two firearms of the same make and model. A folder containing two nearly identical receipts can leave you guessing which one belongs to the missing item. Linking each receipt to its specific entry solves that problem while you still have time to verify the details. A simple reference such as Entry 04 — purchase receipt is enough.
If older records are incomplete, gather what you have and note what’s missing. A dealer name, location, and approximate purchase date can matter later. Keep those details together so you can give an officer a starting point even if you haven’t confirmed the serial number.
Store the Record Where You Can Still Reach It
Keep the inventory in a secure location separate from the firearms it describes. If the storage container is stolen along with its contents, a record kept inside it could disappear at the same time. The ATF treats its personal record form as a document for the owner to retain. atf.gov
For a digital inventory, check who can open the file and whether it sits in a shared folder. If you maintain a backup, test that you can access it from another device. For paper records, use a secure place where you keep other important private documents. Keep full serial numbers and supporting paperwork out of public posts and general household checklists.
Update the entry when you acquire or lawfully dispose of a firearm. If you keep historical records, mark items you no longer own so you can distinguish them from your current inventory at a glance.
Report a Theft or Loss Promptly
If you discover a firearm has been stolen or is missing, contact local law enforcement promptly. Give them the identifying details you have, explain when and where you last knew it was accounted for, and ask for the report number and instructions for submitting additional information. You can provide missing paperwork later. Start the report with the details you already have. ATF
If you bought the firearm from a licensed dealer that has since gone out of business and you need the serial number, tell the investigating agency. The ATF says local law enforcement can submit a records search request to its National Tracing Center in that situation. The center provides those records to law enforcement. ATF
Keep the report number with your private records. If you later find a receipt, confirm a serial number, or locate the firearm, contact the agency handling the report and give them the update.
Start With One Complete Entry
Pick one firearm and write down its manufacturer, model, and serial number. Add any purchase record you can verify, then store the entry separately in a secure place. Once you can retrieve that first entry without searching through old emails or boxes, use the same format for the rest of your inventory.
