The "F-21" and "E-23" refers to the pages of Honda's official parts catalogs. If you walked into a Honda dealer, you would likely look on their parts catalog on their computers and find those pages marked "F-21" and "E-23".
All of the on-line Honda parts sellers (as with other OEMs) are franchised dealers with a brick-and-mortar store. The reason you don't see the page reference is because they chose to get their parts catalog/pricing programs through a third party, one that modifies the retail pricing structure for their profit margin and uses their own page design.
