If we could use use gps co-ordinate then it would make all the life simpler. Imagine how many time you type those address info on the forms and not to forget typing mistakes.
When I sign in to Informed Delivery, every month or so the USPS sends a postcard advertising their podcast (“Mailin’ It!”)
https://usps-mailin-it.simplecast.com/
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.
