Ever find yourself stuck in a Chick-fil-A drive-thru in Hoover, staring at the bumper in front of you, wondering why that tag starts with a "2" instead of a "1"? You aren't alone. It’s a classic Alabama pastime. Honestly, if you grew up here, you probably learned the big three before you learned your multiplication tables.
Alabama county numbers license plate codes are basically a secret handshake for locals. It’s how we size each other up on I-65. You see a "2" and you know they’re probably headed down to Dauphin Island. You see a "43" and you’re looking at an Auburn fan—or at least someone who lives near the plains.
But the system is actually a lot more rigid (and a little more historical) than most people realize. It’s not just random numbers pulled out of a hat by the Department of Revenue in Montgomery. There is a very specific, somewhat archaic logic to why Jefferson is #1 and Greene is #67.
Why the Numbers Work the Way They Do
The system we use today was set in stone back in the 1940s. At the time, the state decided to rank counties based on their population. But they didn't want to update it every ten years with the census—that would be a logistical nightmare. Imagine having to change everyone's prefix just because a few thousand people moved from Birmingham to Huntsville.
So, they froze the rankings.
The three most populous counties at the time took the top spots. After that, they just went in alphabetical order. That’s why the list feels a little "off" if you look at modern population stats. Madison County (Huntsville) is huge now, but back then? It didn't crack the top three.
The Big Three (The Population Heavyweights)
- 1: Jefferson County. The undisputed king in the 40s and still the most populous today. If you see a "1" on a tag, you’re looking at someone from the Birmingham area.
- 2: Mobile County. The port city took the silver medal.
- 3: Montgomery County. The capital city rounded out the top three.
Everything after that? Alphabetical. Autauga is 4, Baldwin is 5, Barbour is 6, and so on. It stays that way all the way down to Winston at 67.
Actually, wait. Winston isn't 67. If you're looking at the list, you'll notice a few quirks. The alphabetical order is based on the names as they stood decades ago. This is why Madison County is actually 47. Yes, the fastest-growing part of the state, home to NASA and Redstone Arsenal, is stuck with number 47 because "M" comes late in the alphabet.
The Full 1-67 Breakdown
You don't need to memorize these, but it’s pretty handy to have them when you're bored in traffic. Here is how the alabama county numbers license plate system actually lays out across the state.
1 to 10: Jefferson, Mobile, Montgomery, Autauga, Baldwin, Barbour, Bibb, Blount, Bullock, Butler.
11 to 20: Calhoun, Chambers, Cherokee, Chilton, Choctaw, Clarke, Clay, Cleburne, Coffee, Colbert.
21 to 30: Conecuh, Coosa, Covington, Crenshaw, Cullman, Dale, Dallas, DeKalb, Elmore, Escambia.
31 to 40: Etowah, Fayette, Franklin, Geneva, Greene, Hale, Henry, Houston, Jackson, Lamar.
41 to 50: Lauderdale, Lawrence, Lee, Limestone, Lowndes, Macon, Madison, Marengo, Marion, Marshall.
51 to 60: Monroe, Morgan, Perry, Pickens, Pike, Randolph, Russell, Shelby, St. Clair, Sumter.
61 to 67: Talladega, Tallapoosa, Tuscaloosa, Walker, Washington, Wilcox, Winston.
Notice Tuscaloosa? It’s 63. For a county that hosts over 100,000 people on a Saturday in the fall, being 63rd on the list feels weird. But again, "T" is at the end of the alphabet. That’s the only reason.
The "New" Alphanumeric Chaos
If you’ve bought a car recently or renewed your tags, you might have noticed things are looking... different.
For decades, the format was simple: County Number - Letter - Numbers. For example, 1A-12345. But Alabama ran out of combinations in the big counties. There are only so many ways you can arrange those digits before you hit a wall.
Starting around late 2021 and early 2022, the state rolled out a new "standard" plate (the one with the mountains and the "Heart of Dixie" slogan). With it came a new numbering system. Now, you’ll see things like 1A01B23. It looks like a password your IT guy would make you use.
Kinda confusing? Definitely. But the first one or two digits still represent the county. If the plate starts with 47, it's still Madison. If it starts with 58, it’s still Shelby. The state hasn't abandoned the county-coded system, they just made the rest of the string way more complex to avoid running out of "real estate" on the metal.
Does it Actually Matter?
Technically, no. Your insurance doesn't change because of the number on your plate, and the police aren't going to pull you over just because you're a "1" driving in "67" territory.
However, it matters for ad valorem taxes. In Alabama, you pay your tag taxes to the county where you live. This is why the county number is so prominent. It’s a quick visual cue for law enforcement and tax officials to make sure you aren't "tag jumping"—registering your car in a cheap, rural county while actually living in a high-tax urban area.
Common Misconceptions
People get this stuff wrong all the time. One of the biggest myths is that the numbers change every few years based on the new census. As we covered, they don't. The 1940s-era rankings are basically a permanent fixture of Alabama law.
Another one? That "personalized" tags don't have county numbers. Actually, most of them don't! If you get a "Save the Cahaba" plate or an "Auburn University" plate, the county number is usually replaced by a different prefix or moved to a tiny vertical sticker on the side.
And let’s talk about the "O." Alabama does not use the letter "O" on license plates. They use the number "0" (zero). If you’re trying to register a personalized tag that says "COOL," it’s going to technically be "C00L." Just a little trivia for your next trivia night at the brewery.
What to Do if You Move
If you move from, say, Birmingham (Jefferson) to Alabaster (Shelby), you can’t just keep your "1" tag forever. When your registration expires, you’re supposed to go to the Shelby County license office, pay your taxes there, and get a new plate that starts with 58.
If you're caught with an outdated county tag, it’s usually just a "fix-it" ticket, but it can be a headache.
Pro-Tip for 2026: Most counties now allow you to renew online. You don't have to sit in those miserable plastic chairs at the probate office for three hours anymore. Just make sure your address is updated with the USPS and the Department of Revenue first, or your new "58" tag might end up at your old "1" house.
Next Steps for Alabama Drivers:
- Check your current tag: Take a look at those first two digits. Does it actually match the county where you live? If not, you might be looking at a fine during your next renewal.
- Verify your renewal month: Alabama uses a staggered system based on the first letter of your last name. Don't be the person who realizes in December that their "S" month was back in September.
- Explore Specialty Plates: If you hate having a number on your plate, look into the 100+ specialty designs. Most of the money goes to the charity or school on the plate, and you get to ditch the "alphabetical ranking" system entirely.
