Pulling RG69 records at College Park

I found some items in the NARA Catalog, but unless I'm missing it, they don't seem to have the box numbers I would need to request them.  Can I give an archivist only this information to get the records pulled?  Is the Container ID actually the Box Number?  Thanks in advance for any help you can give.
