What else could “ISO” mean on Facebook?

Outside of the Facebook Marketplace, ISO has a few different usages.

As internet slang, ISO could also mean “in support of.” This is used to denote support and solidarity with different causes, movements, or events. When used within chat conversations, ISO could also mean “I’m still online,” though this usage is very low as most good chat apps have a dedicated indicator showing the other person as online.

On posts that are very factual in nature, ISO could also be a reference to the International Organization for Standardization. ISO is a global federation of nationwide standard-setting organizations. The organization basically sets standards that members can then follow.

On posts that make references to cameras, photography, and images, ISO refers to the light sensitivity setting of the sensor. You can learn all about ISO in photography in this article.
