Today, I tried to search on Amazon.com's box codes and sizes. I started a page:
A Catalog of Amazon.com Box Sizes

It needs help, though. If you have a box (with the Amazon logo on it) - please take a photo of it. Ideally, it should show the box designation (e.g. "B12") and also the dimensions (e.g. 12x10x8). Make it as many megapixels as you reasonably can. I will update the page as much as I can until all the letters and numbers are filled.

You can include a URL that you'd like linked in your credit. Only the first person who sends me a good photo of a box that I do not have will be listed.

DO NOT send me photos of boxes that are already listed.

Thank you everyone!
