OnDuty SC: How South Carolina's Community Alert System Works

What OnDuty SC does and who runs it

OnDuty SC is a community alert system run by the South Carolina Law Enforcement Division (SLED) that sends emergency notifications to residents and businesses across the state. The system broadcasts alerts about active threats, missing persons, weather emergencies, and other public safety events through text messages, emails, and phone calls. You choose which types of alerts you want to receive and how you want to receive them.

SLED manages the system centrally, but local law enforcement agencies—police departments, sheriff's offices, and emergency management officials—decide when and what to send. This means alerts are tailored to your area rather than state-wide broadcasts for every incident. The system is free to join and has no subscription fees.

Key Takeaways

• OnDuty SC sends emergency alerts by text, email, and phone call based on incidents in your area that local law enforcement determines are urgent.
• You sign up on the OnDuty SC website and choose which alert types (weather, missing persons, active threats) and delivery methods you prefer.
• The system covers all 46 South Carolina counties, though the frequency and types of alerts vary by location depending on local law enforcement activity.
• Alerts are sent by local police, sheriff's offices, and emergency management—not by a central state office—so response times and alert criteria differ by jurisdiction.

How to sign up for OnDuty SC alerts

Visit the OnDuty SC website and enter your phone number, email address, or both. You will be asked to confirm your location by entering your street address or selecting your county. The system then shows you which local agencies cover your area and what types of alerts they typically send.

After confirming your address, you choose your alert preferences. You can select specific alert categories—such as weather warnings, missing persons, traffic incidents, or public safety threats—and decide whether you want notifications by text, email, phone call, or any combination. You can update these preferences at any time by logging back into your account.

Once you submit your information, you are added to the system immediately. You do not need to wait for confirmation; alerts will begin arriving based on your chosen settings and local law enforcement activity in your area.

Types of alerts OnDuty SC sends

OnDuty SC alerts cover several categories, though not every local agency sends every type. Weather alerts include severe thunderstorms, tornadoes, flash flooding, and winter weather warnings. Missing persons alerts go out for endangered or abducted children, seniors with cognitive impairment, and other cases where public help is critical to safety.

Public safety alerts notify residents of active threats, armed suspects at large, or other immediate dangers in your neighborhood. Traffic and road alerts inform you of major accidents, road closures, or hazardous conditions. Some agencies also send alerts about community events, road construction, or utility outages, depending on local priorities.

The specific alerts you receive depend on which local agencies serve your area and which categories they have activated. A rural county sheriff's office may send fewer alerts overall than a city police department in a more densely populated area. You can always adjust your preferences if you are receiving too many or too few notifications.

How alerts are sent and what to expect

When a local law enforcement agency decides an alert meets their threshold for urgency, they send it through the OnDuty SC system to all registered users in the affected area. Text messages typically arrive within seconds to a few minutes. Email alerts may take a few minutes longer. Phone calls are placed to numbers you have registered and may go to voicemail if you do not answer.

Alert messages include the type of incident, the area affected, and what action residents should take—such as "shelter in place," "avoid the area," or "call 911 if you see this person." Missing persons alerts include a photo and description. Weather alerts specify the type of warning and affected counties.

You will not receive an alert for every incident in your area, only those that local law enforcement determines pose a public safety risk or require community awareness. This means the system avoids alert fatigue while ensuring you get information when it matters most.

Managing your OnDuty SC account and preferences

Log into your OnDuty SC account at any time to change your contact information, update your address, or modify which alert types you want to receive. You can add multiple phone numbers or email addresses if you want alerts sent to a spouse, business partner, or family member at different locations.

If you move to a different county or city, update your address in your account so you receive alerts for your new location instead of your old one. If you want to stop receiving alerts entirely, you can delete your account through the website. There is no penalty for leaving and rejoining later.

If you do not receive an alert you expected, it may mean the incident did not meet your local agency's alert threshold, or you may not have selected that alert category in your preferences. Check your settings to confirm you have enabled the types of alerts you want.

OnDuty SC coverage across South Carolina counties

OnDuty SC operates in all 46 South Carolina counties, but the agencies using the system and the alerts they send vary by location. Urban areas like Charleston, Greenville, and Columbia typically have more frequent alerts because more agencies participate and more incidents occur. Rural counties may send fewer alerts overall.

When you sign up, the system shows you which agencies in your area are active on OnDuty SC. Some counties have multiple agencies—city police, county sheriff, and emergency management—all sending alerts through the same system. Others may have only one or two agencies participating. This does not mean rural areas are less safe; it reflects differences in incident volume and agency resources.

If you live near a county line or travel frequently between counties, you can register multiple addresses and receive alerts for each location. This is useful for people who work in one county and live in another, or who own property in multiple places.

Frequently Asked Questions

What if I do not have a smartphone or email?

OnDuty SC can send alerts by phone call to a landline or basic cell phone. You do not need a smartphone or email address to receive alerts, though having both gives you more options. If you only have a landline, register that number and select phone call as your delivery method.

Can I receive alerts for multiple counties?

Yes. You can create separate accounts for different addresses, or register multiple phone numbers and email addresses within a single account. This is useful if you work in one county and live in another, or if you want alerts for a vacation home or business location.

How do I know if an alert is real and not a scam?

OnDuty SC alerts come directly from local law enforcement agencies and include specific details about the incident, location, and recommended action. Scammers typically ask for money or personal information; legitimate OnDuty SC alerts never do. If you are unsure, call your local police non-emergency line to confirm.

What happens if I move out of South Carolina?

OnDuty SC only covers South Carolina. If you move to another state, you will need to check whether that state has a similar alert system. You can delete your OnDuty SC account and sign up for your new state's system when you relocate.

Can I opt out of certain alert types but keep others?

Yes. In your account settings, you can choose exactly which alert categories you want to receive—weather, missing persons, public safety, traffic, or others—and deselect the rest. You can change these preferences as often as you like without deleting your account.
