Mercari sells everything: electronics, clothing, collectibles, toys, books, home goods. That makes it different from Poshmark (fashion-first) or Grailed (menswear). Your username doesn't need to signal a specific niche unless you want it to.
Before you pick, here's what Mercari allows:
- 3 to 20 characters
- Letters, numbers, underscores, and hyphens
- No spaces
- Must be unique across all Mercari accounts
If you're also selling on eBay, Poshmark, Depop, or Etsy, check the same name on all of them at once. Username Inspector generates the profile check links for all platforms simultaneously. If nothing below fits, NamingToolbox can generate ideas from keywords related to what you sell.
General and versatile
These work across any inventory and won't box you in if what you sell changes.

Before you commit
Take your top options to Username Inspector. It checks availability on Mercari, eBay, Poshmark, Depop, Etsy, and more at once, without the tab-hopping.
Mercari separates your username (your profile URL handle) from your display name (what buyers see in listings and reviews). See our Mercari display name vs username guide for how the two work together before you commit to a name.
If your first choice is taken, our guide on what to do when your username is already taken has strategies for finding a close variation that still reads like a real brand.
