How to search for a RN for pants

[liawrig.nq8rdwqa3]

Hello, I've been told there is a database for RN#'s.  I tried searching many times for the RN # for clothing and never get an exact hit.

Do you know where this database is?  I'm searching for Gap womens stretch pants RN 54023.  I get jeans, I get dresses but not what I'm looking for.

That RN is the number that indicates items are Old Navy/Gap. It's no more specific than giving the company. (There aren't specific extensions for different styles.)

Searching by RN number isn't going to narrow down to a specific style. If you're looking for a specific item, you need to search for it by brand and description and weed through all the listings.
