No idea if relevant in your situation, but postal companies are crazy good at mapping indicators to physical addresses. F.ex. high-throughput OCR in the 1960s!

No idea if relevant in your situation, but postal companies are crazy good at mapping indicators to physical addresses. F.ex. high-throughput OCR in the 1960s! [1] To look at it another way, they were one of the first companies with access to big data-scale training sets (all mail flow!), albeit due to electronic storage limitations, persisted in the form of physical mail. When you're running at a volume where a < 1% error rate means opening a new floor of manual sorters, you get pretty good at things. And it's a perfect environment for continuous improvement (customer abstracted from actual implementation, well specified process input and output interfaces, fallback plans for exception handling, and internal authority to experiment).
