Selling on Mercari
Use this guide to prepare your Mercari account for Nifty and understand Mercari’s verification steps, listing limits, and quantity rules.
Account verification
To safely use a third-party listing tool, you must first verify your information:
Go to Settings → Verifications and verify your phone, email, and government ID
Go to Settings → Tax Center and submit your W9
Go to Settings → Account Security and ensure either SMS or email is selected
Sign out of Mercari and sign back in — ensure you receive the verification code
Payment method
To create new listings on Mercari, you must first add a valid credit or debit card:
Add a credit/debit card to My Payment Methods
Go to your Tax Center and ensure the payment method is set to a credit/debit card
Confirm the changes by creating a test listing (you can delete it immediately after)
Listing limit
Mercari uses a progressive listing limit system:
New accounts start with a 100 listing limit
Your limit increases by 100 listings for each completed sale
For example: after 1 sale your limit becomes 200, after 2 sales it becomes 300, and so on
Important: Listing limits are handled directly by Mercari, and you'll need to reach out to their Support team with any issues.
Quantity
Mercari only supports quantity of 1 per listing. If you sell multi-quantity items and use Auto-Adjust Quantity, Nifty handles this automatically — see Enabling Auto-Adjust Quantity for details.
Duplicate listings
When listing via Mercari's API, sometimes two listings are created instead of one. This is a known issue and has already been raised to our Mercari counterparts.
If this happens, go to the Duplicates page in your Inventory Manager and follow the steps in Finding and Fixing Duplicates.
