A new service now allows New Yorkers to know when a sex offender moves in or out of their area.

New Yorkers can sign up to receive the alert via e-mail, text message, fax or phone. The State Division of Criminal Justice partnered with the Emergency Management Office to offer the service.

Those who sign up will get the message when a Level 2 (an offender of moderate risk) or a Level 3 (an offender of high risk) moves in or out of the area they have registered for, which can be a county, zip code, or specific address.

The state sex offender registry currently has more than 30,000 offenders.
