Perhaps you don’t want your street address visible to everyone. Mail forwarding services typically provide a new street address for your postal mail and then will forward the received envelopes and packages to any address the customer specifies.
Mail forwarding services have been available for years but now such services have moved into the digital age. You can have your physical mail sent to such a service and then have it scanned and delivered electronically to you wherever you are.
Scanning of the contents is not mandatory. Instead, you can have the received envelopes and packages forwarded to you (without being opened) in the same manner as old-fashioned mail forwarding services. You can choose the delivery option on a case-by-case (or envelope-by-envelope) basis.
