Why not an email address that you can add a physical address to on the platform of your national postal service? Have parcels be sent to the email address, and the postal service resolves that at dispatch time to your current address. No hassle when moving, no spreading your address everywhere, easy to remember.
The USPS is currently delivering some mailpieces electronically.
When I sign in to Informed Delivery, every month or so the USPS sends a postcard advertising their podcast (“Mailin’ It!”)

This is a virtual postcard, so while I can read it in my email or on usps.com, I won’t necessarily find a paper copy delivered.
It is my understanding that commercial mailings can also use this mechanism. I receive some marketing as original JPEG quality, rather than being scanned in grayscale.
