FFL Change nobody noticed

[BillinBama]

Huh, I was reviewing my FFL for a online transfer and just noticed that one number had changed from my previous one (which hasn't changed in the entire time I've had the FFL).  the two digit "5H" changed to "8H" when my license renewed last year.  I never noticed, I've been giving out the old number on all NICS checks and using it for multiple handgun sales reports (which I found out the DO read), and everything else since I've had it memorized forever.  Strange.

From an inter-web search:

A Federal Firearms License (FFL) number is a 15-character string issued by the ATF that contains valuable information about the licensee. The format is typically displayed as:

[Region]-[State]-[FIPS]-[Type]-[Expiration]-[Unique Sequence]

The meaning of each specific digit and character is broken down below:

1. Region (Digit 1)

The first digit represents the ATF administrative region where the business is located.

  (e.g., 1 is Southeast, 5 is Southwest, 8 is Mid-Atlantic).

2. State/IRS District (Digits 2-3)

  A 2-digit number identifying the specific state or IRS district. This code must match and verify the geographical region indicated by the first digit.

3. FIPS Code (Digits 4-6)

  A 3-digit number representing the Federal Information Processing Standards (FIPS) code, which pinpoints the specific county where the FFL is located.

4. License Type (Digits 7-8)

  A 2-digit code indicating what activities the license permits. Common types include:

   . 01: Dealer in firearms other than destructive devices

   . 02: Pawnbroker

   . 03: Collector of Curios and Relics (C&R)

   . 07: Manufacturer of firearms.

   . 08: Importer of firearms

   . 06: Manufacturer of ammunition only

5. Expiration Date (Digits 9-10)

A single digit followed by a single letter. FFLs are valid for three years.

 . Digit 9: The final digit of the expiration year (e.g., "5" means 2025).

 . Digit 10: The expiration month, assigned alphabetically from A-M. (A = January, B = February, and so on, skipping the letter "I").

6. Unique Identifier (Digits 11-15)The last five digits serve as a unique, sequential number assigned by the ATF to differentiate that specific license from every other FFL.

How to Verify an FFL

Because each section relies on precise, cross-referenced data (e.g., matching the region to the state code), you can instantly verify whether an FFL is legitimate by checking it on the official ATF FFL eZ Check portal.

Yeah, well mine changed from 5H to 8H, meaning it now expires Aug of 2028, which is correct, and the previous one expired Aug of 2025.  But I failed to note that and have been quoting my old 5H for the better part of a year now, and it's been accepted.

As pstidan notes the date code changes with each renewal.  Every three years I have to order a new rubber stamp with my FFL number due to this minor change in the number.

Is there a mechanism to self report yourself to the ATF if you discover an error on your own part? Sounds like you’ve been providing an invalid FFL # for official federal background check purposes. In the flying world, be have a mechanism to file a report in the name of safety and possibly forgo punitive action from the FAA. Curious if the FFL/SOT world does also?

Well, I've been doing it on transfers for the better part of a year, I would hate to have to go back and document all of them.  Plus, NICS inquiries are supposed to be destroyed after 90 days do most of them are moot now anyway.

The first 3 and last 5 of the FFL are the main indicators, even for the FFL EZ Check. The rest was likely over looked, I wouldn't sweat it.
