A Bidder ID is the unique name that is used to identify yourself on a Pooldomains.com auction. When you place a bid in an auction, your Bidder ID will be displayed to all other participants. When you first create your Pooldomains.com account, we assign a random bidder ID.
Please note that your bidder ID can be changed only once. For more information, please visit our article: Can I change my Bidder ID?
