Later this summer, we'll begin checking the computer you use to list an item to see whether it's one of the computers you regularly use. If you list an item using a different computer (e.g. at a friend's house, in a hotel, at the library), we'll ask you to confirm that it's really you listing the item.
Confirming your identity is easy. We'll make an automated call to one of the phone numbers on your account - you can choose which one. If you can't receive a call at one of those numbers, you'll be able to add another number by answering your secret question, or verify your identity with us in Live Chat.
Please take a minute to update your contact information.
You should always keep the telephone number on your account up to date so that eBay and your trading partners can get in touch with you. If you have a mobile phone, we strongly encourage you to add this as a secondary phone number so that you can confirm your identity when you're away from one of your usual computers.
