Knowing your buyer
We want all your sales to be safe and successful. Here are some ways to help make your sale go smoothly.
The chart below explains the icons that a buyer can have next to their user ID.
The user has been a registered eBay user for 30 days or less.
The user has changed their user ID within the last 30 days.
Request a buyer's user ID
For privacy reasons, you can only use this feature if you've completed a previous transaction with the member whose user ID you're requesting.
If you know only a buyer's email address and need to find their user ID, use the Find a member feature. This feature is useful if you receive emails from buyers who have not specified their user ID and for whom you can't locate a listing.
If we can't find a previous transaction that you have in common with the buyer, consider emailing the buyer to request his or her user ID.
Request a buyer's contact information
Like most people, buyers sometimes have emergencies, illnesses, or computer problems. If your buyer has mostly positive Feedback with little or no mention of problems, be patient. Your buyer may not be able to respond to you right away for legitimate reasons.
Limits on buyers
For each of your listings, you can limit or block who can bid on or purchase your items. You can create your own list of eBay members who aren't allowed to bid on or buy your items. Before blocking a buyer, we recommend that you send an email explaining why you won't accept bids or Buy It Now purchases from them in the future.
You can also select buyer requirements for your listings by going to the Seller Preferences section in My eBay. These requirements are based on characteristics, such as buyers who are registered in countries you don't ship to, rather than specific user IDs.
