Type someone's name into the Mercari search bar and you'll get a pile of unrelated listings, never a person. That's not a bug. Mercari built its entire search function around products, and it never bothered adding a way to look up people. If you've spent ten minutes tapping around the app trying to find a specific seller, you already know this.
The good news is there are still real ways to get to a seller's profile. None of them are hidden inside a menu you missed. They just aren't where you'd expect.
Why this is harder on Mercari than other apps
eBay used to have a proper member search tool, then quietly removed it. Depop and Poshmark both let you search by username directly from the main search bar. Mercari is different: it never had a people-search feature to begin with. The app was designed around browsing categories and scrolling listings, and finding a specific account was never part of that design.
That's why so many people end up on Reddit asking the same question. It's a little strange that a marketplace this size never built a way to look someone up, but that's the reality, and the workarounds ended up living in forum threads instead of Mercari's own help pages.
The direct profile link
Every Mercari account, whether they've sold once or a thousand times, has a public profile at the same predictable web address.
- Go to
mercari.com/u/and add the exact username right after it. - Open that page in a browser (this works on your phone's browser too, not just desktop).
- If the profile loads, you've found them. You'll see their listings, ratings, and how long they've been on the platform.
- If you get an error page instead, the username either doesn't exist anymore or you've got it slightly wrong.
Usernames are case-insensitive and don't include spaces, so double-check for that before assuming an account is gone. A single typo is the most common reason this method "fails."
When you don't know their exact username
This is usually where people actually get stuck. You remember a name, maybe roughly, but not the precise handle, and Mercari's own search still can't help you.
Google can, though. Type site:mercari.com/u/ followed by the name you remember, in quotes, and it'll often surface a profile that Mercari's internal search would never find, since Google indexes those public profile pages even though Mercari's own search bar ignores them.
If you've bought from this person before, your order history is faster than any search trick. Open the order and their username is sitting right there in the details. Tap it and you're on their profile, no memory required.
Old messages work almost as well. Any past conversation with a seller links back to their profile from inside the thread itself, which is often quicker than digging through order history, especially if the exchange happened outside an actual purchase, like asking a question about something you never ended up buying.
And if you've got even one listing from them saved, whether it's a link you bookmarked or a screenshot a friend sent you, tapping their name on that listing takes you straight to everything else they have for sale.
None of this requires the seller to do anything on their end. They're just different doors into the same profile page.
What people are usually trying to do
Most searches for a Mercari seller fall into one of a few buckets, and it's worth knowing which one you're in because it changes which method above is fastest.
Reconnecting with someone you bought from. You want to see if they've restocked, or you just want to leave a review. Order history is your quickest path.
Checking someone out before you buy. Maybe a listing looks a little too good, or the seller has very few reviews. Their profile shows a rating history and how long they've been active, which is usually enough to make a call.
Following a competitor if you sell yourself. Resellers often keep an eye on a few sellers in their niche to see what's moving and how they're pricing things. Clicking through from one of their listings gets you there fastest.
Confirming a name before you register. If you're setting up your own account and want a specific username, checking whether it already belongs to someone else is a completely different task from the ones above, and it's covered in the next section.
What Mercari keeps to itself
Mercari's profiles are public by design; that's how the platform works at all. But there are real limits on what you can see.
You won't find a phone number, email address, or real name unless someone put it in their bio voluntarily, which is rare. Usernames are the only identifier most sellers ever share. Sellers can see your shipping details after you've bought something, since they need that to ship the item, but that information isn't visible to other buyers browsing the same listings.
There's also no way to message someone outside of an active listing or a past order. If you're trying to reach a seller cold, without having bought anything from them, your options are limited to whatever contact info they've chosen to share on their own profile.
Checking if a username is available before you sign up
If you're on this page because you're about to register a Mercari account, not because you're hunting for someone else's, the process is basically the reverse of everything above. Instead of confirming an account exists, you want to confirm one doesn't.
Go to mercari.com/u/yourusername, swapping in the name you want. An error page means it's open. A profile loading means someone beat you to it.
Mercari also splits your username from your display name, and the two follow different rules. If you haven't picked a name yet, our Mercari username ideas list is a good starting point, and the display name vs. username guide explains why both fields matter before you commit to one.
That's rare flexibility. eBay, Poshmark, and Etsy all cap how often you can change yours, and some of them cap it permanently. If you're building a name across several platforms at once, Username Inspector checks Mercari and ten other selling platforms together so you're not repeating the profile-link trick eleven separate times.
Frequently asked questions
Can you search for a seller by name on Mercari?
No. Mercari's search only looks through item listings, not people, and there's no name-based member search anywhere on the platform. If you know their exact username, the profile URL trick works. If you only know their real name, Google, your purchase history, or your message threads are the way in instead.
Does Mercari have a seller directory or member search?
No, and it never has. Unlike eBay, which used to have a member search tool before removing it, Mercari simply built its search around products from the start. The profile URL is the closest thing to an official workaround.
How do I find a Mercari seller I bought from before?
Open your order history and tap the order. The seller's username is right there, and tapping it takes you straight to their profile, even if you don't remember their name at all.
Why can't I find a seller I know exists on Mercari?
A few common reasons: the account was deactivated or banned, the seller changed their username since you last saw it, or you're misremembering the exact spelling. Try the Google site search method first, since it can surface older or slightly different usernames that a direct guess would miss.
