Enable your R+L account to accept external rate requests

You must have an R+L Carriers account number to use this app. If you don’t have one, contact R+L Carriers at 800-543-5589.

Your R+L Carriers account must be enabled to accept external rate requests for the R+L LTL Freight Quotes app to work. To enable your account, you must have a MyRLC Username & Password. If you don’t, click here to access a form to request them.
