It's completely free for an agent to join our network and be eligible for referrals. Service zip codes allow for agents to put their names on the list for zip codes where they are open to receiving referrals. Then they will be assigned a rank based on their performance. If they want to increase their rank in their service zip code that is when they would want to look at SGD. 

Non SGD agents can add up to 12 service zip codes to their profile in their portal.
