What does "ISO" mean?

ISO stands for “In Search Of” and is often used in online marketplaces, forums, or social media when someone is looking for something specific. It’s a quick way to say “I’m looking for” or “I need,” and is typically used when people are seeking items, information, or recommendations.

For example, if someone is looking to buy a specific vintage jacket, they might post “ISO: black leather jacket, size medium” on a marketplace site or in a fashion group. It’s a shorthand way to communicate that they’re on the hunt for something specific.

ISO is also used in more casual settings, like social media posts or in comments, when people are looking for advice or recommendations. Someone might post “ISO recommendations for good brunch spots in NYC,” for instance.
