The primary eBay customer service number is no secret: it is 1-866-540-3229. However, if you want to speak to a real human being anytime soon, you need a passcode and possibly even a different phone number. You might spend most of the day on hold if you call without getting these first.

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.

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.
