# What does IIRC mean?

Canonical: https://postmesh.app/glossary/iirc

IIRC stands for If I recall correctly. IIRC stands for if I recall correctly, also read as if I remember correctly. People add it when sharing a fact from memory that they're fairly sure of but haven't double-checked, which invites others to correct them.

## What IIRC means

IIRC is short for if I recall correctly. The Oxford English Dictionary gives both if I recall correctly and if I remember correctly, and an archived Dictionary.com entry says the same, describing it as something people use when retrieving information they may not be completely sure of.

That's the whole job of IIRC. It marks a statement as coming from memory. The writer is saying: I think this is right, I haven't looked it up, and I'm open to being corrected. "The sequel came out in 2019, IIRC" is a fact offered with a small asterisk.

IIRC is not an opinion marker. It doesn't say "I think this is good" the way [IMO](/glossary/imo) does. It says "I think this is true." That difference matters when you're reading a thread. A claim tagged IIRC can be checked. A claim tagged IMO can only be agreed or disagreed with.

Dictionary.com spells out the pronunciation as the four letters, I-I-R-C. Out loud, the full phrase, or a more natural "if I remember right", is usually easier.

## Where IIRC comes from

Like many of the hedging abbreviations, IIRC comes from early online discussion. The OED's earliest evidence for it is from 1990, in a reply within an online discussion thread, the kind of message board conversation that thrived before the web. The OED added IIRC in 2016.

It has kept a slightly technical, forum-flavored feel ever since. You'll find it most where people discuss facts at length and care about getting them right: hobby forums, help threads and Q&A communities. Merriam-Webster doesn't have a full dictionary entry for IIRC, but its list of common texting abbreviations includes it, defined as if I recall correctly.

## How people use IIRC on social media

IIRC is most at home in text-heavy communities, where people recall details for each other.

- On Reddit, it's everywhere: in answers to questions, corrections, trivia and recaps. A reply to the [OP](/glossary/op) that starts with IIRC is offering help from memory.
- On X and Threads, it often appears when someone adds context to a news story or a quote, like when something was announced or who said it first.
- On YouTube, viewers use it in comments to point out an earlier video or a detail from a past episode.
- On Discord and in group chats, it's used for plans and logistics: "the game starts at 8 iirc".
- On LinkedIn, people tend to write "if I remember right" in full, but IIRC appears in comments from technical folks.

Some example messages, written for this page:

- IIRC the store closes early on Sundays
- They covered this in episode 12, iirc
- The first version didn't support dark mode IIRC
- IIRC she said the deadline was Friday, but double check
- That rule changed a couple of years ago iirc
- iirc we split the bill last time so it's my turn

Notice the fourth example. Pairing IIRC with "double check" is common and good practice. It makes the uncertainty explicit and tells the reader not to rely on the detail without confirming it.

## Why IIRC is a useful habit

IIRC is a small piece of honesty that makes online conversations better. Memory is unreliable, and most of what people say in comments comes from memory rather than research. Tagging those claims helps readers weigh them.

It also makes corrections easier. When someone writes IIRC and gets a detail wrong, the person correcting them doesn't have to argue. The original writer already admitted they might be off. That keeps a thread friendly. Compare "You're wrong, it was 2018" in response to a flat claim with "Close, it was 2018" in response to an IIRC.

There's a limit, though. IIRC is a hedge, not a shield. If you're stating something that could hurt someone if it's wrong, like a dosage, a legal deadline or a safety rule, look it up before you post. A quick check is better than a polite disclaimer.

## IIRC on Reddit and in Q&A threads

If you spend time on [Reddit](/platform/reddit), you'll see IIRC more than almost anywhere else. That fits the format. Most [subreddits](/glossary/subreddit) run on people answering each other's questions from experience, and a lot of that experience is half-remembered. IIRC is how careful commenters mark the difference between "I checked" and "I'm pretty sure".

It's also common in [AMA](/glossary/ama) threads and long recaps, where someone is retelling events from a while back. "IIRC the original plan was to launch in spring" tells readers the timeline is from memory, not from notes. When a correction arrives, the thread can move on without anyone losing face.

A few habits make IIRC answers more useful in these communities:

- Put IIRC next to the uncertain detail, not at the start of a long answer that's mostly certain. That way readers know which part to check.
- Edit your comment if someone corrects you. A short "Edit: it was Thursday, not Friday" helps everyone who reads later.
- Add a link when you find the source. An IIRC that turns into a confirmed fact is the best outcome.

Communities that value accuracy tend to reward this. A clearly hedged answer that turns out to be slightly wrong usually gets a friendly correction. A confident answer that turns out to be wrong usually gets piled on.

## How to reply to IIRC

How you answer depends on whether they remembered correctly.

**Did they remember correctly?**
- Yes → Confirm and, if you can, add the source: "Yep, it's in the FAQ under billing."
- No → Correct gently with the right detail: "Close, it actually moved to Thursday."
- You're not sure either → Say so, or check before replying. Two guesses don't make a fact.
- It's important → Point to an official source so nobody relies on memory: a help page, schedule or announcement.

*IIRC invites correction. A kind, specific correction is the expected reply.*

If you're answering lots of questions in a community, a reply that links the source beats one that only says yes or no. The [Reddit comment generator](/tools/reddit-comment-generator) can help you draft a clear answer, but check every fact it suggests.

## When not to use IIRC

IIRC is polite and low-risk, but it signals uncertainty, and there are places where uncertainty is the wrong message. It also adds a small burden for the reader, who now has to decide whether to trust you or check for themselves. Skip it in these cases:

- When you can easily check. If the answer is one search away, look it up. IIRC on something you could have verified in seconds can read as lazy.
- In customer support. A brand replying "IIRC the return window is 30 days" sounds unsure about its own policy. State the policy, with a link.
- On anything where a wrong answer causes harm: medical, legal, financial or safety details.
- In formal writing. Use "if I remember correctly" or, better, confirm the detail and state it.
- With readers who may not know it. IIRC is less familiar than IMO or LOL, especially outside forum culture.

**IIRC fits when**
- [ ] You're sharing a fact from memory in a casual setting
- [ ] Being slightly wrong wouldn't hurt anyone
- [ ] Checking isn't practical right now
- [ ] You're happy to be corrected

If you find yourself typing IIRC on a detail you'll need again, that's a sign to look it up once and save it. The second time you share it, you can drop the hedge.

## IIRC vs AFAIK, FWIW and IMO

IIRC belongs to a family of hedges that all came out of early online discussion. They're easy to mix up, but each hedges something different.

| Term | Stands for | What it hedges |
| --- | --- | --- |
| IIRC | If I recall correctly | Your memory of a fact |
| AFAIK | As far as I know | How complete your knowledge is |
| FWIW | For what it's worth | How much weight your point deserves |
| IMO | In my opinion | Marks a view, not a fact |
| IMHO | In my humble opinion | A view, with modesty or irony |

**IIRC**
- I learned this before
- My memory may be off
- "It launched in March, iirc"

**AFAIK**
- This is true as far as I know
- There may be things I haven't heard
- "AFAIK it's still free"

*IIRC doubts your memory. AFAIK admits the limits of your knowledge.*

The pair people confuse most is IIRC and [AFAIK](/glossary/afaik). IIRC means you once knew something and are recalling it. AFAIK means you're reporting what you currently know, without claiming to know everything. [FWIW](/glossary/fwiw) is softer still: it offers a point and lets the reader decide its value. For opinions rather than facts, use [IMO](/glossary/imo) or [IMHO](/glossary/imho).

## Questions

### Is IIRC rude?

No. It's polite. It admits you might be wrong, which makes it easier for others to correct you without an argument.

### Does IIRC mean recall or remember?

Both readings are correct. The Oxford English Dictionary lists if I recall correctly and if I remember correctly.

### What's the difference between IIRC and AFAIK?

IIRC hedges your memory of something you learned before. AFAIK means as far as I know, and hedges how complete your current knowledge is.

### How do you pronounce IIRC?

As the letters I-I-R-C, according to Dictionary.com. Out loud, saying if I remember correctly is often simpler.

### Can I use IIRC in an email?

In a casual note to a colleague, yes. In anything formal or customer-facing, check the fact and state it, or write the phrase out.

### Where is IIRC used most?

In text-heavy communities such as Reddit, forums, Discord and comment sections, where people recall details for each other.
