Finding a celebrity’s personal contact info is like chasing a ghost. You've probably seen the clickbait. "KSI’s private number leaked!" or "Call JJ right now!" Usually, these are just scams. Or they're dead ends. It's frustrating. Honestly, the quest to find out what is KSI's phone number usually leads to a rabbit hole of sketchy websites and prank videos.
JJ Olatunji—better known as KSI—is one of the biggest stars on the planet. He’s a YouTuber, a boxer, a musician, and a co-founder of Prime. When you're that famous, your phone number is guarded like the crown jewels. If his actual personal digits were just sitting on a public forum, his life would be a non-stop barrage of "Fat Neek" memes and FaceTime requests. He’d never get a second of peace.
The truth about the leaks
We’ve seen it happen. Streamers like IShowSpeed have famously "leaked" KSI's number during live broadcasts. It happened as recently as late 2025 and several times in previous years.
What actually happens when a leak occurs?
The phone basically explodes. Thousands of calls and texts flood in within seconds. Usually, JJ’s team is on it immediately. The number gets deactivated or changed before the stream even ends. So, if you're looking for a number from a YouTube clip from six months ago, you're out of luck. It's a dead SIM card now. Basically, those "leaked" numbers are a snapshot of a moment that has already passed.
Why you won't find it on a database
There are plenty of "celebrity contact" sites that claim to have his home address or private mobile. Most of these are paid services. They might give you an old business line or the office of his management, but they rarely have his actual iPhone's number.

Think about it. If you were JJ, would you keep the same number for more than a month if it was public? Probably not.
How to actually contact KSI (The real way)
If you're trying to reach him for a reason—maybe you're a fan with a cool project or a business looking for a collab—the "phone number" route is the worst way to go. It’s invasive. It’s also likely to get you blocked.
There are legitimate channels that actually work. They might not be as instant as a text message, but they are monitored by people whose job it is to relay messages to JJ.
For business and professional inquiries
KSI isn't a one-man show anymore. He’s a massive brand. His management team handles the heavy lifting.

- Manager: Mams Taylor is the main man here. He’s the head of Proper Loud and manages most of JJ’s career, especially the boxing side (Misfits Boxing).
- Email: The official contact listed for business inquiries is often Mams@properloud.com.
- Booking Agents: For live music or touring, he has specific agents like Mark B. who handle the logistics.
For fans and the "Sidemen" community
If you just want to say hi or show him some art, social media is your best bet.
- Twitter (X): He’s incredibly active here. He sees the mentions.
- Reddit: The r/ksi subreddit is his main connection to the fans. He does "TNTL" or "Reddit Review" videos constantly. If you post something that gets upvoted to the top, he will see it and probably talk about it on camera.
- Instagram: Good for tagging him, though his DMs are almost certainly filtered to "Request" only from people he doesn't follow.
Common scams to avoid
The search for what is KSI's phone number is a goldmine for scammers. You’ll see TikToks where someone "leaks" a number and says "Text him now, he’s replying to everyone!"
Don't fall for it.
These are often "premium rate" numbers. You send a text, and you get charged $5 on your phone bill. Or, they’re phishing attempts. They’ll ask for your name and email to "verify" you’re a fan, and then sell your data. Kinda slimy, right?
Sometimes, people on Discord will pretend to be his assistant. They’ll ask for a "processing fee" to get you a shoutout. JJ doesn't work like that. If it feels like you're being asked for money to get his attention, it's a scam. Every single time.

Why privacy matters for creators
We sometimes forget that behind the "KSI" persona is just a guy named JJ. He’s talked about the mental toll of having zero privacy. In his documentary and various podcasts, he’s mentioned how weird it is when fans turn up at his house or find his private details.
Having your phone number leaked isn't just an annoyance; it's a security risk. It links to banking, two-factor authentication, and private family chats. That’s why his circle is so tight.
If you really want to support him, engage with the content. Buy the Prime (if you can find the rare flavors), watch the Sidemen Sundays, and post on the Reddit. That’s the ecosystem he’s built for interaction.
Actionable steps for reaching out
Instead of searching for a phone number that doesn't work, try these steps:
- Focus on the Subreddit: Build a high-quality post on r/ksi. Use a catchy title and good visuals. This is the most "direct" line to his eyeballs.
- Contact Management for Business: If you have a legitimate professional proposal, email Mams Taylor or use a service like Influencer Matchmaker.
- Use Official Sidecard/Fan Mail: Occasionally, the Sidemen will open a PO box for fan mail or specific videos. Keep an eye on the Sidemen social accounts for those rare windows.
- Follow the Verified Accounts: Only trust information coming from his verified Blue Check accounts on X, Instagram, and YouTube.
Basically, the "secret" phone number is a myth. If it exists, it changes every time a kid in a bedroom decides to leak it for clout. Stick to the official paths—it’s more respectful and way more likely to actually get you a response.
