• Know how to obtain a buyer’s User ID, or contact information.

Request a buyer’s User ID

• For privacy reasons we limit the use of this feature to those members who have completed a previous transaction with the member whose User ID is being requested.

• If you only know 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 you cannot locate their listing.

• If we cannot determine a transactional relationship, you should request that the buyer send you their User ID using email.

Request a buyer’s contact information

Like you, 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.

• If you don't get an email response, you can request your buyer's phone number. Sometimes a phone call helps make communication easier.

• If your item was a regular listing that ended without a reserve price or a Reserve Price Auction where the reserve is met and you are unable to contact your winning buyer, your listing may fall under eBay's Unpaid Item Policy. This policy will tell you how to request a fee credit from eBay if your buyer does not pay.

• If you have you requested your buyer's contact information and it is not valid, please review our contact information policies.

Limits on Buyers

For each of your listings you can limit which buyers may bid on or purchase your items. You can create your own list of eBay members who will no longer be permitted to bid or buy any of your listings. Before blocking a buyer, eBay recommends that you email him or her and clearly state why you will not accept bids or Buy It Now purchases from him or her in the future. Learn about Managing Bidders and Buyers.

You can also set up buyer requirements for your listings by going to the Seller Preferences section in My eBay. These requirements are based on characteristics, rather than specific User IDs. For example, you can block all buyers that have a negative Feedback score.
