You’re standing on the corner of Vinewood Boulevard, Trevor is covered in something that definitely isn't ketchup, and you're bored. You've done the heists. You've flown the jets. But have you actually looked at your phone? Not the real one in your pocket—the iFruit in your hand. Most people think the smartphone in Grand Theft Auto V is just for saving the game or checking emails from your angry mother. It’s actually a direct line to some of the weirdest programming glitches and easter eggs Rockstar Games ever hid.
GTA V secret phone numbers aren't just for cheats, though that’s how most people find them. They’re a legacy. Since 2013, players have been dialing random digits just to see if the game world pushes back. Sometimes it does.
Why Do These Numbers Even Exist?
Rockstar has a thing for detail. It’s borderline obsessive. Back in the GTA IV days, dialing numbers was a huge part of the gameplay. In GTA V, they switched mostly to a "Contact" list, but the manual dialer stayed. Why? Because it’s the perfect place to hide the stuff that doesn't fit in a menu.
Think of these numbers as the "backdoor" to the game's engine. When you dial a specific string of digits, you aren't just making a call; you're triggering a script. Some of these are leftovers from the development phase—tools the devs used to test things quickly. Others are just there to mess with your head.
Black Cellphones: The Most Famous Secret Number
If you’ve spent any time in the deepest corners of Reddit or the GTA Forums, you’ve heard of 1-999-367-3767. This is the big one. This is "Black Cellphones."
Dial it. Go ahead.
When you hit call, an explosion goes off right above your head. Your phone’s theme changes to a sleek, pitch-black aesthetic. It’s weirdly satisfying. But here’s the thing: nobody actually knows why Rockstar put this in. It was discovered years after the game launched. Some players, like the famous mystery hunter WhizL, spent months trying to figure out if it triggered a secret mission or a UFO sighting. It doesn't. Or at least, it hasn't yet. It just changes your phone and blows something up. It's chaotic. It's GTA.

The Numbers That Actually Change the Game
Most people just want the cheats. They want to fall from the sky or turn into a god. These numbers are basically the modern version of the "R1, R2, L1, Circle" codes from the PS2 era.
- Skyfall (1-999-759-3255): This is the best way to travel if you don't care about living. It teleports you high into the atmosphere and lets you skydive without a parachute. Pro tip: if you want to survive the landing, you have to hit the ground head-first. Physics are weird in Los Santos.
- Drunk Mode (1-999-547-861): Use this if you want the screen to wobble and your character to stumble like they just finished a gallon of Blarneys. It’s useless for missions, but hilarious for walking down the pier.
- Explosive Melee (1-999-4684-2637): Ever wanted to punch a bus so hard it flips over? This is the number. Every punch is a grenade.
Honestly, the GTA V secret phone numbers list is long, but these are the ones that actually feel like you’re breaking the rules. You can also spawn vehicles. Want a Rapid GT sports car? Dial 1-999-727-4348. Need a Buzzard Attack Chopper because the cops are closing in? 1-999-289-9633. It’s faster than trying to find a cheat sheet on your real phone while being shot at.
The Creepy and the Useless
Not every number does something cool. Some are just... unsettling.
Have you tried calling the characters from the story when you aren't playing as them? If you're Franklin and you call Michael, he might pick up. But try calling someone who died during your playthrough. Usually, it just goes to voicemail. But sometimes, especially with the GTA V secret phone numbers found on billboards around the city, you get a busy signal that sounds... off.
Dialing the "Dead" Numbers
There are numbers scattered across Los Santos on real estate signs and side-of-the-road advertisements. Most of them give you a generic "The party you are calling is not available" message. But some, like the ones found in the derelict parts of Sandy Shores, play weird static or high-pitched tones.
911: The Most Practical Secret
It sounds stupid, but a lot of players forget you can actually dial 911. It’s not a "secret" in the real world, but in the context of the game's mechanics, it’s a tool. You can call the police, the fire department, or an ambulance to your location. If you’re in a shootout with a gang and you call the cops, they’ll show up and start fighting the gang for you. It’s a great way to create a massive three-way proxy war without doing much work.

The Connection to the Mount Chiliad Mystery
We have to talk about the mountain. Mount Chiliad is the epicenter of every conspiracy theory in this game. For years, players have been trying to use GTA V secret phone numbers to trigger the mural's secrets.
There was a theory that dialing certain numbers at 3:00 AM during a thunderstorm while standing on the peak would summon a jetpack. People tried everything. They dialed the numbers found in the game’s source code. They dialed numbers from GTA IV.
The reality? Rockstar definitely tracks what we dial. In the "Doomsday Heist" update for GTA Online, they finally acknowledged some of these myths. While the jetpack eventually became a buyable item in Online, the phone numbers remain the primary way players "poke" the game to see if anything else is hidden.
How to Dial These Properly
If you're new to this, you might be confused. You don't just go to your contacts.
- Bring up your phone (Up on the D-pad for consoles, T or Backspace on PC).
- Navigate to your Contacts.
- Press the "Manual Dial" button (Square on PlayStation, X on Xbox, Spacebar on PC).
- Enter the digits and hit the call button.
Keep in mind: using these numbers—specifically the cheat-related ones—will disable your Achievements or Trophies for that session. If you’re a completionist, don't dial these and then save your game. You’ll regret it when that "100% Completion" trophy doesn't pop.
The "Epsilon Program" and Beyond
The cult in the game, the Epsilon Program, has its own set of numbers and websites. If you're deep into the lore, dialing their "helplines" usually results in Cris Formage-related nonsense. It’s a nice touch that adds layers to the satire.

What’s truly fascinating is how these numbers have shifted over the years. When the game moved from PS3/Xbox 360 to the "Next Gen" (PS4/Xbox One) and then to the "Next Next Gen" (PS5/Xbox Series X), some numbers were added. The Black Cellphone number, for example, didn't even exist in the original 2013 launch. It was a gift for the players who upgraded.
Actionable Steps for Your Next Session
Ready to try it? Don't just dial them all at once. Start with the ones that change the world state.
- Test the Black Cellphones number (1-999-367-3767) first just to see the explosion and the UI change. It’s the easiest way to confirm you’re doing it right.
- Go to the top of Mount Chiliad at night and try the "Change Weather" number (1-999-625-348-7246). Keep dialing it until it strikes lightning. It completely changes the vibe of the game.
- Check the billboards. Next time you’re driving through the desert, actually stop and look at the phone numbers on the signs. Some of them are just jokes, but a few have unique audio clips.
There is no "Ultimate Secret" that wins the game. There is no number that unlocks a hidden city. But these GTA V secret phone numbers are the threads that hold the mystery together. They are the leftovers of a dev team that wanted to make sure that even if you stopped playing the missions, you’d never stop exploring the world.
Go break the game a little. It's what Trevor would want.
Next Steps for Players:
To maximize the effect of these numbers, combine them. Use the "Moon Gravity" number (1-999-356-2837) alongside "Skyfall" to see how far you can glide across the map. Just remember to keep a separate save file so you don't lose your hard-earned achievements.
