The purpose of the P.O. Box is to allow companies to take advantage of a mailbox available at your convenience (located in a MBE Center) storing all the mail that has been sent. Therefore, the address of your company does not appear. Establishing the registered office of a company means assigning it a postal and physical address, which it can then use on all its documents (articles of association, communications, invoices, etc.). The address of a company is also the relationship with its customers and partners. It means being present at the right place, at the right time.
