If the listing is current and indexed, you can search by item number by entering the number directly into the search bar. Just paste your own item number of those digits at the end of the page address. That will work even if the listing has ended within ninety days or if it is not yet indexed.

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.

Sold or Ended listings are typically removed from eBay after ninety days. If you know the item number or the exact title you might possibly be able to find a cached version of the page on Google, but it is highly unlikely that any associated images would still be viewable after so much time.

On average, eBay takes between 10% and 15.55% of the final selling price in fees. This percentage can increase if you're selling internationally or using promoted listings. It's important to factor in all of these fees when pricing your items to ensure that you're making a profit after all fees are taken into account.
