The short version
A Federal Firearms License is issued by ATF and lets you engage in the business of dealing, manufacturing or importing firearms. You apply on ATF Form 5310.12, pay a fee that ranges from $30 to $3,000 depending on license type, send fingerprints and a photo for each person who controls the business, and notify your local chief law enforcement officer. An ATF Industry Operations Investigator then meets with you, and if everything checks out the license arrives in the mail.
That summary is accurate and also a little misleading, because it skips the parts that cause trouble. The application form is not hard. Getting your city to confirm the location is allowed, deciding who counts as a responsible person, and understanding what you are signing up for in recordkeeping take more thought than the form does.
A license is for a business. ATF issues dealer licenses to people who intend to engage in the business of selling firearms. If your real goal is buying guns for yourself at a discount, the qualification interview is going to be an awkward conversation. The collector license (Type 03) exists for a narrower version of that goal.
Decide what you want to do
Start from the activity, not the license number. The table below covers the common cases.
| If you want to | You likely need | Read |
|---|---|---|
| Run transfers, sell guns, do gunsmithing | Type 01 | Becoming a dealer |
| Lend money against firearms | Type 02 | License types |
| Collect curio and relic firearms across state lines | Type 03 | License types |
| Build, assemble or refinish firearms for sale | Type 07 | License types |
| Sell suppressors, short-barreled rifles, machine guns | Type 01 + Class 3 SOT | Class 3 SOT guide |
| Manufacture NFA items | Type 07 + Class 2 SOT | FFL + SOT roadmap |
A realistic timeline
The federal clock is 60 days from the time ATF receives a properly completed application. What happens around that window is up to you.
| Stage | Typical time | What slows it down |
|---|---|---|
| Zoning and business setup | 1 to 6 weeks | Home occupation permits, HOA questions, forming an LLC |
| Preparing the application | A few days | Getting clean fingerprint cards for every responsible person |
| ATF processing and background checks | 3 to 6 weeks | Missing information, rejected prints |
| Qualification interview | Scheduled by the field office | Investigator workload in your area |
| License in hand | Usually within 60 days of filing | Anything that makes the application incomplete |
Details on each stage are in the step-by-step application guide.
What it costs
The ATF fee is the smallest line in most budgets. A Type 01 license is $200 for the first three years and $90 to renew. A Type 07 is $150 either way. Add $500 a year if you want to sell NFA items as a Class 3 dealer.
Where the real money goes: a decent safe or vault, an alarm, liability insurance, bound book or electronic records software, business registration and an accountant who knows excise tax if you manufacture. For a home-based transfer dealer, all of that can stay in the low thousands. A storefront is a different conversation, and inventory is the big number there.
