Confirmation of registration on ebay is carried out under a special unique link, which will be indicated in the letter from the EBAY support service. Such a letter comes to the mailbox specified during registration. You can confirm registration with an alternative method — entering a special code in the confirmation field of your pseudonym. This code is also indicated in a letter from EBAY support service. It is the activation of your account (pseudonym) that is the completion of the registration procedure of the auction user.
