I've had my California Brokers license for many years and have never done anything with it—never registered as a Realtor, signed up for the MLS, etc.

- Does signing up for the MLS allow you to view listings in states outside of where you are licensed?

- Is there a main MLS or Realtor website to sign up? It seems like there are so many different websites. What MLS do realty offices register with?

No, MLS's are regional and are confined to the state/area in which you are licensed. Contact your brokerage or local NAR office and find out what you have to do to get signed up with the MLS in your area.

There are about 750 different MLS systems in the country.
