No, but that is a common misconception. The NMLS is only an engine for licensure. Your NMLS# is your registration within the system that each state has agreed to use. So, when you enter all information in the NMLS for a license application to a particular state, that information is saved on your personal account or MU4. If you choose to pursue a license in another state, the second state will then already have most of your information through the NMLS and your personal NMLS#.
