How to find someone on Reddit without knowing their username

I’m trying to locate a Reddit account belonging to someone I know, but I have no idea what their username is. Are there any tricks people use to identify accounts based on posts, photos, or linked social profiles?

Hey @ThreadShadow, that’s a pretty common challenge when you’re doing online research! As a freelance journalist, I’ve run into this countless times when trying to dig up info on sources or just get a fuller picture of someone online.

Reddit can be tricky because of the anonymity, but there are definitely a few tricks I’ve picked up over the years.

  • Reverse Image Search: If you have any photos you suspect they might have posted, a reverse image search (using tools like Google Images, TinEye, or even Yandex, which sometimes has better luck with faces) can sometimes lead you to their Reddit posts if the image was also shared elsewhere or if Reddit is indexed. I’ve had success with this when someone used the same profile picture across multiple platforms.
  • Unique Phrases or Quoted Content: Do you know if they’ve ever posted a very specific opinion, a unique turn of phrase, or perhaps quoted something obscure? Searching those exact phrases on Reddit (using quotation marks) can sometimes narrow things down. It’s a long shot, but if they’ve said something truly distinctive, it can pay off.
  • Linked Social Profiles: This is often the most fruitful. Many people, despite trying to be anonymous on Reddit, will link to other social media profiles in their user bio or in their posts, especially if they’re promoting something or cross-posting content. I usually start by looking for their other known social media profiles and then scouring those for any mentions or links to Reddit.
  • Associated Email Addresses/Phone Numbers: If you have an email address or phone number, sometimes people use the same one for account recovery or sign-ups across various platforms. While you can’t directly search Reddit by email, sometimes if you’re using a broader OSINT tool that aggregates data, it might link accounts.

Speaking of which, I recently tested out Findsio, and it was surprisingly helpful for identifying several social media profiles linked to a phone number I was researching for a story. It’s one of those tools that can sometimes bridge the gap between seemingly disparate online presences.

Good luck with your search! It can be like finding a needle in a haystack, but with a bit of persistence and the right approach, you can often uncover more than you’d expect.

Hey @CuriousGuy — good tips, mostly. Reverse image search and quoting unique phrases do work, but don’t oversell them: Reddit strips EXIF and many images are resized/edited, so TinEye/Yandex/Google often come up empty. Site:reddit.com searches and exact-phrase Google queries are the real bread-and-butter; Pushshift-style archives (or the Reddit API) help if you know date ranges or subreddits.

About Findsio and similar pay tools: they can surface links faster, but expect false positives, stale records, and privacy/legal limits — they’re conveniences, not magic. Always validate matches with multiple signals (posting patterns, timezone/language, cross-posts). And be careful with ethics and laws — do not cross into harassment or doxxing. — OldForumUser

Hey @ThreadShadow, that’s a tough one, but definitely a common OSINT challenge! I’ve been experimenting with finding accounts myself, and your question about linked social profiles reminded me of something.

I recently tried using this tool:

to see if it could find accounts linked to an email or phone number. What I noticed when testing it was that it did surface quite a few social media links for various profiles, but it wasn’t always accurate for every platform, and sometimes the links were old. It’s a bit of a hit-or-miss, but it definitely highlighted some connections I wouldn’t have found otherwise. Have you tried any other email/phone lookup tools? I’m always curious to hear what others are using!

@OldFU56 Thanks — totally agree about false positives. Reverse image searches often fail for me too. I’ve had better luck with site:reddit + exact-phrase Google searches and checking Pushshift for date ranges. I also tried Findsio after someone suggested it — I put a phone number in and it showed several linked social profiles; it saved time but I still validated matches (timestamps, language, mutual friends) because some were stale. And yeah, always mind the legal/ethical side. Appreciate the tips!

@ThreadShadow Hey, I’ve been lurking on this thread and figured I’d share my two cents since I’ve dealt with this exact situation before!

A few months back I was trying to find my college roommate’s Reddit account because I remembered him posting funny stories about our dorm life. What actually worked for me was searching specific phrases I remembered him saying - super niche stuff like inside jokes we had. Used Google with site:reddit.com "exact phrase" and eventually found him.

The reverse image search route rarely works for Reddit in my experience since most people don’t post selfies there anyway. But if you know they’re active in certain subreddits (gaming, local city subs, hobby communities), that narrows things down a lot.

I’ve also heard about tools like Findsio that can link phone numbers or emails to social accounts - might connect some dots if their Reddit is tied to a known email.

What info do you actually have on this person? That might help us suggest better approaches!

@ThreadShadow – I’ve been down this rabbit hole recently myself, honestly. The site:reddit.com Google search trick that @MikeOS mentioned is probably your best bet to start. I tried using Findsio for phone number lookups when I was trying to verify whether my partner had active profiles on dating apps like Tinder and Hinge, and while it did surface a few social media accounts, Reddit wasn’t always indexed perfectly there.

If you know any specific subreddits they might hang out in, that helps massively – I spent hours scrolling through local city subs and relationship advice threads looking for writing patterns. Also, check if they’ve ever mentioned their Reddit username on Instagram, Twitter, or Discord. People slip up more often than you’d think.

What’s prompting the search if you don’t mind me asking? Sometimes knowing the context helps narrow down where to look first.

Hey @MikeOS, you hit on some excellent points, especially the power of targeted search engine queries! The site:reddit.com "exact phrase" method is incredibly effective because it leverages Google’s advanced indexing capabilities. Search engines build massive inverted indexes, mapping keywords to document locations. When you add site:reddit.com, you’re telling the engine to narrow that search to only Reddit’s domain, dramatically reducing noise.

Regarding social media lookup tools like Findsio, they often operate by aggregating publicly available data from various sources, sometimes linking email addresses or phone numbers to social profiles through cross-referenced databases or public APIs. They can be good starting points, but as you noted, validation is key due to potential stale or inaccurate data. It’s about triangulating information from multiple signals.
