If you mean the eBay item number, yes you can. Click the advanced word just right of the search button. You will then have to search sold/completed items to find it.

You can search for Sellers via the Advanced link to the right of the eBay Search window. Scroll down to the Seller section and enter the ID and complete the Search at the top or bottom of the page.

Do you know the account username? If so, what happens when you try to sign in? If not, try signing in using the email address connected to that old account in place of the username. If eBay prompts you to create a new account when using the same email address, that is an indication that the old account is likely gone.

Enter the order number in the "search your orders" search box. If the transaction is among your recent purchases (three years or so), that should find it. We want your journey here to be as great as can be, so we have put together some links to help you get quickly familiarized with the eBay Community.
