Have you ever been scrolling through Facebook Marketplace, Reddit, or even a group chat when someone suddenly types “ISO tickets” or “iso a roommate asap”? The first time you see it, you might pause and think… wait, what does ISO mean? Is it some tech term? A typo? A new Gen Z slang word?
You’re definitely not alone. Short forms like this pop up everywhere online, and they’re not always obvious.
Quick Answer:
ISO means “In Search Of.” It’s a casual and practical way of saying you’re looking for something.
🧠 What Does ISO Mean in Text?
In texting and online conversations, ISO stands for “In Search Of.” People use it when they’re looking for something specific — whether it’s an item, service, person, or recommendation.
It’s basically a shorter way to say:
- “I’m looking for…”
- “Does anyone have…?”
- “I need…”
For example:
“ISO used iPhone 13 in good condition.”
This simply means the person is looking to buy a used iPhone 13.
You’ll often see it in buying/selling groups, community pages, or online forums.
In short: ISO = In Search Of = Looking for something.
