Christmas Clever Slogan

You can use the Certified Mail of Public Administration to write to any address?

the answer is no.

writes me the service center fact:

"... the PostaCertificat @ is a free

electronic communication between citizens and public administration;
provides a communication channel
closed and exclusive agreement between Government and Citizen: No,
fact, required to report outside of the channel, such as between
Nationals (although both have PostaCerificat @). "

Good to know!
