Interesting, the last/only time I had to write code to determine delivery points was very early in my career (IBM mainframe COBOL) when postnet barcodes were a new thing and it was always just the last two digits of the street address. I see in the current CASS technical guide that a record type H may have multiple delivery point. Learn something new every day. Thanks.

Edit. As an aside, I think current Microsoft word still calculates it that way when you "bookmark" and address and insert a barcode field. At least it doesn't seem to be sending a query out to the USPS.
