You may confidentially register as many addresses in the county as you wish, and they will continuously monitor the addresses and send you an email alert if a new offender registers an address within the specified radius of any address you register. There is no cost for this service and no limit to the number of addresses you can register – your email address and physical addresses are all confidential. Tell your friends and neighbors and be sure to register your home, school, work, gym, day care, park, soccer field, parents or children’s homes – any address of interest to you.
