You’ve probably opened a message, seen “PRN,” and paused for a second like, “Wait… what does THAT mean?” It happened to me the first time a friend texted, “Reply PRN.”
I stared at my screen, wondering if it was slang, a typo, or some secret code I wasn’t cool enough to know. 😂
Don’t worry — if you’ve felt that confusion, you’re not alone. PRN looks technical, and it actually is, but people now use it casually in texting too.
Quick Answer: PRN means “as needed.” It’s a short, simple way of telling someone to do something whenever necessary — not urgently, just whenever it comes up.
What Does PRN Mean in Text?
PRN stands for “as needed.” It originally comes from the Latin phrase pro re nata, used in medical settings to describe something that should be given or done only when necessary — not at a fixed time.
In texting or social media, PRN means:
➡️ Do it whenever you need to.
➡️ No strict timing.
➡️ Only if required.
Example:
“Send me the files PRN — no rush.”
In short: PRN = “as needed” = only when necessary.
