USPS IMb DAFT to Digits

[lukevin]

So I may have bitten off more than i can chew. I'm trying to help a friend report on his mailing data but the data that he has is a DAFT code in them that you can convert into the USPS output report IMb digits to confirm they mailed and reached their destination.
I should be able to use the code below to take and convert the DAFT code into the IMb digit code format below but I don't know how to apply it to the data in column A to convert it and output it into O-T.

I know I'm asking for a lot of direction here and I apologize, I've got a ton of informational resources here i can share from USPS but none show me an actual formula method (which is what i expected when I commited to making this fix for him, I would like to resolve this and learn where what i'm missing in the process of decoding the DAFT's to digits especially if i'm over complicating this
