How to Find a Seller on Any Reselling Platform

Maybe you bought something great from a seller on Mercari and want to find them again. Maybe you're researching competitors on Poshmark. Maybe someone mentioned their eBay shop name in a Facebook group and you want to check it out.

Whatever the reason, finding a specific seller isn't always straightforward. Most reselling platforms bury their user search or don't have one at all. Here's how to find anyone's profile on each platform — the fast way.

The Fastest Method: Direct Profile URLs

Every reselling platform uses a predictable URL pattern for seller profiles. If you know someone's username, you can go directly to their profile without searching:

Just replace "username" with the seller's actual name and paste the URL into your browser. If the profile exists, it loads. If it doesn't, the platform shows a "not found" page — which is also how you check if a username is available when setting up your own accounts.

Want to check a username across all seven platforms at once? Username Inspector generates all of these direct profile links automatically. Enter a username and it creates clickable links for every platform in seconds.

eBay

eBay has the most robust seller search of any platform on this list.

Direct URL: ebay.com/usr/username

Through the platform:

1. Go to ebay.com and use the main search bar
2. Search for the username or seller name
3. Look for seller results in the sidebar, or filter by seller using Advanced Search
4. Alternatively, use Advanced Search and enter the seller's username in the "Sold by" field to see all their active listings

Other ways to find eBay sellers:

• Google search: Type site:ebay.com/usr/ "sellername" to find their profile through Google
• Through past purchases: Go to My eBay > Purchase History and click the seller's name on any previous order
• Through feedback: If you left feedback for them (or they left it for you), their profile is linked there

eBay is the easiest platform for finding sellers because it actually wants you to search for them. The eBay username checker functionality is built right into the search bar.

Poshmark

Poshmark username search works, but it's mixed in with product results, which can make it noisy.

Direct URL: poshmark.com/username (this goes to their closet)

Through the platform:

1. Open the Poshmark app or go to poshmark.com
2. Tap the search icon
3. Type the username
4. Look for the "People" tab in the search results (you may need to switch from the default "Listings" tab)

Other ways to find Poshmark sellers:

• Search @username: Adding the @ symbol before the name can help surface the user profile over product listings
• Google search: Type site:poshmark.com "username" to find their closet through Google
• Through Posh Parties: If you interacted with them during a party, check your party history

The challenge with Poshmark is that search defaults to showing product listings, not people. Switching to the People tab is the key step most users miss.

Depop

Depop's search is straightforward if you know where to look.

Direct URL: depop.com/username

Through the platform:

1. Open the Depop app
2. Tap the search icon
3. Type the username
4. Switch to the "Members" or "People" tab in the search results

Other ways to find Depop sellers:

• Search @username: Searching with the @ prefix targets user profiles specifically
• Google search: Type site:depop.com "username" to find them through Google

Remember that Depop usernames are always lowercase with no special characters. If someone tells you their shop is "VintageFinds," the actual Depop username is "vintagefinds." Check our username rules guide for the full breakdown of what each platform allows.

Etsy

On Etsy, you're usually looking for a shop, not a user profile. The shop name is what appears in the URL and what buyers search for.

Direct URL: etsy.com/shop/shopname

Through the platform:

1. Go to etsy.com
2. Type the shop name in the search bar
3. Look for the shop in the results — Etsy sometimes shows a "Shop" result card at the top
4. If you only see product results, try adding "shop" to your search (e.g., "vintagevault shop")

Other ways to find Etsy sellers:

• Google search: Type site:etsy.com/shop/ "shopname" for a direct Google result
• Through past purchases: Go to Your Account > Purchases and Reviews and click the shop name
• Through favorites: If you previously favorited their shop, check your favorites list

Etsy's search is heavily product-focused. Searching for a shop name often returns that shop's listings rather than the shop page itself. Using the direct URL is almost always faster.

Grailed

Grailed doesn't have a prominent user search feature, making the direct URL approach especially useful here.

Direct URL: grailed.com/users/username

Through the platform:

1. Go to grailed.com
2. Use the search bar and type the username
3. Look for the seller in the results — Grailed may show a user result alongside product listings

Other ways to find Grailed sellers:

• Google search: Type site:grailed.com/users/ "username" for a direct hit
• Through past purchases or messages: Check your transaction history or inbox

Grailed's search is product-first. If typing a username into the search bar only returns listings, use the direct URL — it's the most reliable method.

Vinted

Finding a seller on Vinted works, but the platform's search is primarily designed for products, not people.

Direct URL: vinted.com/member/username

Through the platform:

1. Open the Vinted app or go to vinted.com
2. Use the search bar and type the username
3. Look for member results — Vinted may show a "Members" section alongside item results

Other ways to find Vinted sellers:

• Google search: Type site:vinted.com/member/ "username" to find them
• Through past orders: Check your purchase history for the seller's profile link

One thing to know: Vinted usernames are lowercase only. If someone shares their name as "ThriftQueen," search for "thriftqueen" instead.

Mercari

Finding a seller on Mercari is one of the most common questions in the reselling community — and for good reason. Mercari's in-app search is product-only by default.

Direct URL: mercari.com/u/username

Through the platform:

1. Open the Mercari app or go to mercari.com
2. Search for the seller's username in the search bar
3. If you only see product results, you may need to look for a "Seller" filter or scroll through results to find their profile

Other ways to find a seller on Mercari:

• Google search: Type site:mercari.com/u/ "username" — this is often the fastest and most reliable way to find a Mercari seller
• Through past purchases: Go to your order history and tap the seller's name
• Through messages: If you've messaged the seller before, find the conversation in your inbox
• Through ratings: If you left them a rating, their profile is linked from the review

Mercari makes it surprisingly difficult to find a specific seller through the app's built-in search. The direct URL or Google search method is almost always faster than trying to find someone through the app itself.

Check Multiple Sellers at Once

If you're trying to find the same seller across multiple platforms — or checking whether a competitor has claimed a name on all seven — doing it one platform at a time is slow.

Username Inspector generates direct profile links for all seven platforms at once. Enter a username, select which platforms to check, and click through the links. You'll see in seconds whether that seller exists on eBay, Poshmark, Depop, Etsy, Grailed, Vinted, and Mercari.

This works for:

• Finding a specific seller you want to buy from on a different platform
• Researching competitors to see where they sell
• Checking username availability before setting up your own accounts

Quick Tip: Google Is Your Backup

When a platform's built-in search fails — and it will — Google almost always works. The pattern is:

site:platform.com "username"

This tells Google to only show results from that specific platform. It's faster, more accurate, and works even when the platform's own search buries user profiles behind product listings.

Bookmark that trick. You'll use it more than you'd expect.
