Interesting that the post says the term BIN (vs. IIN) isn't commonly used anymore, but it's practically the only thing I've heard them called in the last 10+ years of ecomm dev.

I've seen both. When I wrote the post all the docs from the gateways I had access to called then iin with a historical note on bin. I done have access to those docs anymore though.

Edit: I really need to check when posting from my phone

I don't doubt you, but as an example, the recent notification of BIN/IIN prefix additions for Mastercard uses BIN 19 times and IIN 2 times.

Interesting, maybe I should update that page then.
