Roblox username id numbers are one of those things you don't really think about until you suddenly, desperately need one. Maybe you're trying to set up a cool new rank in a group, or perhaps you're messing around with some scripts in Roblox Studio and realize that names just aren't cutting it. It's funny because we spend so much time obsessing over our display names and making sure our actual usernames look "clean," but behind the scenes, the platform doesn't really care if your name is "xX_DragonSlayer_Xx" or "User12345." To the servers, you're just a string of digits.
Understanding how this works is actually pretty useful if you plan on doing anything more than just jumping into Blox Fruits or Brookhaven for an hour. Your ID is the one permanent thing about your account. While you can shell out 1,000 Robux to change your username, or swap your display name every week for free, that ID stays the same from the second you hit "Sign Up" until the day the heat death of the universe happens (or your account gets deleted, whichever comes first).
Finding Your ID on a Computer
If you're sitting at a desk or on a laptop, finding your roblox username id is honestly a walk in the park. You don't need any weird plugins or "hacker tools" that those sketchy YouTube videos try to sell you. All you have to do is log into the Roblox website using any standard browser like Chrome, Firefox, or Safari.
Once you're logged in, click on your own profile picture or your name to head over to your profile page. Now, look up at the address bar—that long box at the top where the URL is. You'll see something that looks like https://www.roblox.com/users/123456789/profile. That middle chunk of numbers? That's it. That is your unique identifier. You can copy those numbers and paste them wherever you need them. It's definitely much easier than trying to dig through settings menus, mainly because the ID isn't actually listed anywhere in the settings. It's almost like Roblox wants to keep it a little bit of a secret from the casual players.
The Struggle of Finding Your ID on Mobile
Now, if you're on a phone or tablet using the actual Roblox app, things get a little bit annoying. For some reason, the developers decided not to include the URL bar in the app (fair enough, it's an app), but they also didn't put the ID anywhere on the profile page. If you go to your profile in the app, you'll see your display name, your @username, your bio, and your inventory, but that precious number is nowhere to be found.
The workaround for this is to open your mobile browser—like Safari on an iPhone or Chrome on an Android—and go to the Roblox website there. Usually, it'll try to force you back into the app. You have to ignore that "Continue in App" button and hit the tiny text that says "Continue in Browser." Once you're in, just follow the same steps as the desktop version. Go to your profile, look at the URL, and there's your roblox username id. It's a bit of a clunky process, but it's the only way to do it without relying on third-party "ID finder" games which can sometimes be a bit sketchy.
Why Your ID Actually Matters
You might be wondering why anyone would even care about a random string of numbers. Well, if you're a developer, it's everything. When you're writing code for a game, you don't want to use usernames to give people special permissions. Why? Because people change their names. If you give "CoolGuy77" admin rights in your game based on his name, and then he changes his name to "AwesomeDude88," your script is going to break. But if you use his roblox username id, it doesn't matter what he calls himself; the script will always recognize him.
It's also a big deal for trading and external tracking. Sites that track "RAP" (Recent Average Price) for limited items or websites that show your account's history use the ID because it's the only way to keep a consistent record. Even if you've changed your name ten times in the last five years, those sites can track your "evolution" because that ID number links all those names together.
The Legend of the Low ID Numbers
In the Roblox community, there's actually a weird kind of "clout" associated with having a low roblox username id. Since the IDs are handed out in chronological order, the lower your number, the older your account is. If you see someone with a 4-digit or 5-digit ID, you're looking at a literal dinosaur of the internet. They've been around since the mid-2000s.
The most famous ID, of course, is ID #1, which belongs to Builderman. If you go to his profile, the URL ends in /users/1/profile. It's simple, it's iconic, and it's impossible to get. As the platform grew, the numbers exploded. Nowadays, new accounts are being handed IDs that are in the billions. It's a pretty crazy way to visualize just how massive the game has become. Seeing those huge numbers compared to the early days really puts the "growth" of the platform into perspective.
Is it Safe to Share Your ID?
I've seen a lot of younger players get worried about sharing their roblox username id, thinking it's like a password or some kind of private key. Let's clear that up: your ID is completely public. Anyone who visits your profile page can see it just by looking at the URL. Sharing it won't get you hacked, and it won't give someone access to your Robux or your items.
Think of your username as your "nickname" and your ID as your "social security number"—except in this case, the SSN is written on a billboard for everyone to see. It's just an index in a database. The only real "risk" is that if you give it to someone, they can find your profile even if you change your name later. But since your profile is usually public anyway, that's not really a security flaw—it's just how the site is built to work.
Changing Your Username vs. Your ID
It's worth repeating because it confuses people all the time: you can change your name, but you cannot change your ID. When you go into your settings and spend those 1,000 Robux to get a new identity, Roblox just updates the "Username" column in their database. The roblox username id remains the anchor.
This is actually a good thing. Imagine if your ID changed every time you changed your name. You'd lose your place in every group you're in, your game data in every experience would probably be reset (since most games save data via the ID), and your friends list would likely break. Keeping the ID static is the only thing keeping the whole ecosystem from falling apart.
Wrapping It Up
At the end of the day, your roblox username id is just a tool. For most players, it's something you'll never even need to look at. You'll spend your time playing games, chatting with friends, and maybe making some avatars. But the moment you decide to dive a little deeper—whether that's becoming a dev, joining a serious clan, or using external tools—you'll find yourself heading back to that profile URL to grab those digits. It's the one part of your digital identity that is truly yours forever, unchangeable and permanent, no matter how many times you decide you're too cool for the username you picked when you were ten years old.
