Having the most up-to-date emergency contact information for all commercial businesses that the City of Horn Lake serves is very important. When emergencies occur or alarms are activated, dispatcher's need to know who to call right away. If you are a business owner, please print out the Commercial/Business Emergency Contact Form. Fill out the form and return it to the Horn Lake Police Department Communications Center or mail it to the Horn Lake Police Department Operations Division at 3101 Goodman Rd, Horn Lake  MS,  38637.
