Find someone on Reddit by username
Reddit usernames are pseudonymous, yet many people reuse the same handle on services with real profiles. AliaScan takes a Reddit username and checks 3,000+ platforms for the identical handle.

- •The same username on social, developer and gaming platforms
- •Public profiles that may reveal who is behind a Reddit account
- •Cross-platform links built from an exact handle match
How Reddit usernames work
- •Reddit usernames are 3–20 characters and allow letters, numbers, underscores and hyphens
- •A Reddit username can never be changed — the only way to get a different one is to create a new account, which is why throwaways are so common
- •Deleting an account retires the username permanently rather than freeing it, so old names are not recycled to new people
- •Every account is public at reddit.com/user/<username>, and the u/ prefix is a display convention rather than part of the name
Because renaming is impossible, a Reddit username is permanently bound to one account and one comment history — there is no ambiguity about a handle changing hands. The offsetting factor is that Reddit is a pseudonymity-first culture, so a lot of accounts are deliberately created with a name used nowhere else.
How to search a Reddit username in 3 steps
- Copy the Reddit username you want to look up.
- Paste it into the AliaScan search box and start the scan.
- Review the platforms where that handle exists, with a direct link to each public profile.
A common use case: Investigating whether a Reddit account is connected to a known public persona. AliaScan only surfaces information that is already publicly visible on each discussion platform.
What a Reddit username search can’t tell you
A username search cannot see deleted comments, private subreddits, alternate accounts created under different names, or anything tying an account to a real identity. Reddit's throwaway norm means an absent match is unremarkable. Conversely, a distinctive handle appearing on a network with real profiles is one of the more meaningful signals available here.
Distinguish a Reddit username from its display name
- Copy the account’s u/username from its profile rather than the display name shown in a biography.
- Check the original Reddit profile and distinguish the account from posts that merely mention its name.
- Use public self-links to corroborate ownership. Similar interests or writing style alone do not establish identity.
Reddit says finalized usernames cannot be changed, including capitalization, and deleted account names do not become reusable. Deleted posts or inaccessible history cannot be recovered by an ordinary username search.
