To remove your phone number from Mercari, the platform's official help pages only document how to change it to a different one or close your account entirely, meaning you cannot simply delete the number field and leave it blank.
Can you actually remove your phone number from Mercari?
The honest answer is no, not in the way most users expect. Mercari's verified help pages document two relevant paths for phone-number removal: change the number in account settings if you still can log in, or contact Mercari if you cannot access the account or need help beyond self-service. There is no documented standalone "remove phone number" button. If your goal is to stop associating a specific number with your account without adding a replacement, you will need to either change it to a different number or close the account entirely. This limitation is important for anyone concerned about removing phone numbers from accounts and devices for privacy reasons.
Change your phone number in Mercari account settings

Mercari Japan says you may need to verify by passkey authentication or email authentication before entering the new number.

When to contact Mercari customer support instead
Self-service fails in specific scenarios: you are locked out of the account, you no longer have access to the old phone number, or you need help beyond the change-number flow. Mercari U.S. lists phone support at (888) 325-2168 Monday, Friday 8am, 6pm PST. The U.S. help pages in the retrieved results do not give a documented phone-number-removal form or a published support case path specifically for removing a number from an active account. The Japan help results indicate that if you are logged in, you should use the self-service phone-number change flow rather than a separate removal flow.
