Hello, a question, my husband made the appointment to renew his passport online, but they did not give him a confirmation number so he can go to the consulate without any problem?

A notification must arrive on the phone and that is the confirmation and when it arrives it tells you that you have an appointment and tells you the time of the appointment and shows you the email that they sent you with the notification

Thank you very much, I appreciate your help, the appointment was made this Monday and nothing has arrived yet, so you will have to wait for that notification
