Underage user policy
You must be at least 18 years old to be an eBay member.
A person under 18 can use an adult's account with the permission of the account holder. However, the account holder is responsible for everything done with that account.
Make sure you follow these guidelines. If you don’t, you may be subject to a range of actions, including limits of your buying and selling privileges and suspension of your account.
If you think another member is under 18, please report them to us. Make sure to include any relevant information about why you think the member is underage. If you have an email from the member, please be sure to include a copy of it.
Why does eBay have this policy?
When eBay members agree to buy or sell items, they are entering into contracts with each other. In most countries, you must be at least 18 years old to enter into a contract.
