What does IIRC mean?
A shorthand used when giving information from memory while admitting it may need checking.
Also written: iirc · if I remember correctly · if I recall correctly
The meaning
IIRC means “if I remember correctly” or “if I recall correctly.” It qualifies a statement by showing that the writer is relying on memory and is not claiming perfect certainty.
What’s the tone?
Casual, cautious and conversational; usually sincere, but it can sound pointed or sarcastic when correcting someone.
When and how to use it
Use it before, within or after a remembered detail in texts, chats and online discussions. It works well for dates, earlier conversations or past events; in formal or high-stakes contexts, verify the detail instead of relying on the abbreviation.
In a conversation
Original examples to illustrate the expression.
Which room did we use for last month’s workshop?
Room 204, IIRC, but I’ll check the calendar.
IIRC, she said the draft was due Thursday, not Tuesday.
Easy to misread
IIRC is not IRC, the Internet Relay Chat protocol. Compared with AFAIK, it focuses specifically on the reliability of memory rather than the full limits of what a person knows.
A little context
IIRC is a long-established internet initialism used in digital conversation. Contemporary writing references and mainstream news explain both common expansions and show it qualifying remembered details. No definitive first-use date is asserted.
