There are many reasons you may want to look to see if an individual has any outstanding warrants. Perhaps you would like to query about yourself, a relative, or someone you are considering hiring. This is public information and is easily obtainable from several sources depending on the level of the infraction. With a few phone calls, you can find the information you need, and you don't need to identify yourself to do it.
Look up the phone number for the local municipal court or justice of the peace.
Call their number to find information about an outstanding warrant for a Class C misdemeanour, such as a traffic ticket they may have issued.
Look up the number for your local sheriff or police department and call the dispatcher. They will have information about outstanding warrants regarding a Class B or a Class A misdemeanour or a felony.
