Generally, once the application process is over, your trademark will be officially registered. When the registration proceedings are finalized, you will receive a trademark certificate.
You will obtain an electronic certificate by default; however, in most jurisdictions, it is possible to request a paper version of the certificate. A small fee has to be paid to receive it via mail. It will be delivered to the address of your choice.
It is not necessary to have the paper version of your registration certificate, as the electronic certificate serves as an official confirmation.
