An appointment confirmation is proof of your appointment. You receive it after booking an appointment. It shows that your appointment has been officially scheduled.
You often receive it by email, as a letter, as a PDF download, or by SMS. The appointment confirmation may include, for example, the date, time, location, and what you need to bring. It is best to bring it with you to your appointment.
If you do not receive an appointment confirmation, ask the authority or counseling center. This way, you can confirm whether your appointment has been officially scheduled.
