Greetings from Amazon Seller Support,
I understand that you want to know is it acceptable to have different seller accounts for a Mother and daughters or sons who live in the same household.
Please be informed that this is considered as violation to have a separate seller account who lives in a same household. However you are willing to make your childrens to sell in Amazon.
In this case, you can apply for an exception to this policy for the multiple selling account with your childrens. On the Contact Us form, select “Account Settings” and then the “Other account issues” sub-category:
https://sellercentral.amazon.com/gp/contact-us/contact-amazon-form.html
To apply for an exception, you must:
- Provide an explanation of the legitimate business need for a second account
- Have an account in good standing with excellent Customer Metrics
- Have a separate e-mail address, credit card, and bank account for the new account
- Not intend to sell the same products in both accounts
You’ll receive a response to your request within 2-3 business days.
you can directly contact performance to apply for open an another selling accounts for your childrens who are in the sane household by using below email:
seller-performance@amazon.com
So that they will check and help you in opening second account.
Thank you for understanding Amazon policies and conditions.
Have a great day!
