Useful places to begin.
Check the service and the area it covers.
MEMA expressly says its Ask MEMA app feature is not an emergency service and is not monitored around the clock; the app does not replace 911.

What this Mississippi inventory includes.
There are 16 qualifying place records in this state inventory. Jackson (141,196), Gulfport (76,506), Southaven (57,819) are the largest included places. These are Census place estimates for 2025, not current counts of users, warnings or participating agencies.
15 included places have fewer than 100,000 residents; 1 has 100,000 or more. The smallest included record is Starkville at 25,754. The table is alphabetical, so those population differences do not determine which place appears first.
Every row uses the same inclusion threshold of at least 25,000 residents. A smaller town, unincorporated area or omitted census-designated place can still have official services and warnings. A missing name here is a limit of this research inventory, not evidence that a community lacks a reporting or alert service. Read the Census population source.
Use the directory for the task you have.
For local updates, identify the city, county or other authority responsible for the place that matters to you. Follow its current warning-registration instructions where offered. A person’s home, workplace and family can connect them to different jurisdictions, and each provider can have its own enrollment process.
For a police report, begin with the agency’s official reporting information. A place name in a population table does not identify which self-service reports are eligible or which office should receive evidence. For a product question, use Detailr’s business contact instead of an emergency or police reporting route.
Official state information
Keep your official warning channels.
State emergency management resources provide preparedness guidance and links to current public information. Local warning subscriptions and reporting instructions should be checked with the responsible authority.

Find the source for your part of Mississippi.
The inventory is a way to begin a local information search, not a substitute for the agency responsible for an address. Start with your city or county’s official website, identify its police service provider, and check its current warning subscriptions and reporting instructions. A municipal name does not always identify a separate police department.
Among the larger places in this inventory are Jackson, Gulfport, Southaven, Hattiesburg, Biloxi. These names and estimates come from the Census source linked below. Population describes a place; it does not establish the number of app users, participating departments or people receiving alerts.
Choose the channel for the task.
State emergency management resources are a useful starting point for preparedness and official information. A local police agency’s reporting page answers a different question: which incidents it accepts, which recipient is appropriate and whether a self-service route fits the circumstances. Check those eligibility instructions before sending personal information or evidence.
If you need information for several places, keep their sources distinguishable. Home, work and family may connect you to different authorities. Following a participating agency in Lucas is separate from subscribing to official warnings, and a directory entry does not confirm that a department publishes in Lucas or accepts Lucas tips.
Read the inventory with its limits in view.
The table uses a population threshold to keep a national research inventory manageable. It is not a complete list of neighborhoods, unincorporated communities or all census-designated places. A missing place may still have official services and warnings. Use the relevant city, county or state source to continue the search rather than treating absence here as evidence that a service is unavailable.
For a researched local page, follow the original official links and look for the latest instruction. For a department considering Sentinel, begin with a discussion of the actual workflow and operating responsibilities. Information-finding, product evaluation and emergency assistance are distinct tasks; this directory is for the first of those.
