Request a buyer's username

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

  • If you know only a buyer's email address and need to find their username, use the Find a member feature. This feature is useful if you receive emails from buyers who have not specified their username 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 username.

Request a buyer's contact information

. If you've emailed your buyer and they haven't responded, they may have a legitimate reason for the delay.

  • If the issue is important, you can request your buyer's contact information, but only when you've had a successful transaction with them.

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

Limits on buyers

For each of your listings, you can manage bidders and buyers to limit or block who may bid on or purchase your items. You can create your own list of eBay members who will no longer be permitted to bid on or buy any of your items. Before blocking a buyer, we recommend 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.

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 where you don’t ship, rather than specific usernames.
