How to Find an Item Number on eBay
Every eBay listing, whether its an auction or Buy it Now sale, has an item number to identify it. While this number is primarily used to refer to a listing when making a complaint or when sending a payment outside an automated system such as PayPal, the [advanced search tool](http://www.ebay.com/sch/ebayadvsearch?_sofindtype=4) also uses item numbers to find specific listings.
Item Numbers on Listing Pages
Every listing on eBay displays its item number in the **Description** tab. Scroll down below the "People who viewed this item also viewed" section and look on the right side of the page, directly below the Report Item link. If you're having trouble finding the number, press **Ctrl-F** and search the page for **eBay item number**.
