But the post office (by default) uses a simple numbering scheme, which is the de facto standard even though the "legal" address is the one set by the council. Absolute nightmare.
I suspect similar situations arise, on a smaller scale, all over the place. I live in a house (29 Acacia Road) divided into three flats, known as Flat 1 29 Acacia Road, Flat 2 29 Acacia Road, and Flat 3 29 Acacia Road to the council, but known as 29 Acacia Road, 29A Acacia Road, and 29B Acacia Road to the Royal Mail. And as FLAT GND FLR 29 ACACIA ROAD, FLAT 1ST FLR 29 ACACIA ROAD, FLAT 2ND FLR 29 ACACIA ROAD to the Valuation Office Agency. Until very recently, they were known as something else to the Land Registry!
Argh I live in house that's been converted into two flats. One system calls us (to borrow your example) 29 and 29A, another calls us 29A and 29B, and assorted outliers call mine Downstairs, Ground Floor, Grannyflat ..
It must be worse for upstairs, who are simulataneously 29A and 29B. I'm only sometimes 29A but never 29B.
We also have three postcodes, but we're not sure which belongs to who.
Luckily the two flats / six addresses all share the same letterbox.
To add ot that, the "simple" numbering scheme is usually denoted by e.g. "9/8" - Building 9, Flat 8, (which depending on the building layout might be 9 3f2 or 9 2f4). Infuriatingly, many postcode systems will autofill the "9/8" format into an immutable address field, and then reject the address with a forward slash in it...

I think that's where you and the other commentator are talking past each other. Amazon tends to have great managers and senior ICs that get the responsibility and technical divide right.
My experiences outside Amazon unfortunately point towards this being hard to get right in the first instance, and really really hard to fix once it has gone wrong.
In Scotland there are quite a few places where the council use a different tenement flat numbering scheme from the post office. Edinburgh council for example https://www.edinburgh.gov.uk/downloads/file/24357/statutory-....
