Fun fact: PostNL already does this with 100% of the mail processed. The first step in the sorting process is to OCR the address, generate a "KIX" barcode[0], and print that on the letter using special ink if not already present. It's not intended to be user-readable, but anyone with a smartphone can trivially decode the unique destination address from it.
