We can only secure unavailable (already-taken) Poshmark usernames for sellers that can demonstrate trademark ownership of that name. If this applies to you, please contact the Enterprise Operations team with proof of trademark and we can begin the process for you.
For sellers without proof of trademark, we suggest adding a _ or number to your requested username, which usually will open up an available account. Bear in mind, the username is only visible in your closet URL and when sending comments or offers. Your business name (displayed on the closet) can be edited to reflect whatever name you would like to use.
