10-21 Police Phone screenshots
If you work in law enforcement and spend part of your week trying to reach people who never pick up, 10-21 Police Phone is worth a look. It is a Motorola Solutions app, free to download, and it has been on Google Play since October 2015, so it is not a new experiment. The idea is narrow and specific: place calls to citizens from local numbers instead of your personal line, and handle the callbacks that follow without giving out your own number.
The name comes from the radio code for making a phone call. The app is built around two problems officers run into constantly. The first is that unfamiliar or blocked numbers get ignored, so messages do not reach the people who need them. The second is that handing out a personal number invites return calls at any hour. The app addresses both by routing calls over a data connection and presenting a local number to the person on the other end.
I would treat it as an outreach tool rather than a replacement for any part of a department's existing communications setup.
Built for officers who make routine calls
The clearest fit is an officer, detective or community liaison who regularly phones people who are not expecting to hear from law enforcement. That could be a follow-up on a report, a request to schedule an interview, a neighborhood notification or a check-in with someone involved in an open case. In each of those situations the goal is to get a person on the line and have a short conversation, not to run an emergency response.
Agencies that want a shared, consistent way for staff to place those calls are the other natural audience. The app keeps an officer's personal number out of the picture, which matters when the alternative is a phone that rings at home on a day off. Anyone whose job involves a high volume of unanswered calls will recognize the problem the developer is trying to solve.
The app is designed around citizen outreach and the routing of return calls, and the developer points citizens toward a dispatcher when they need immediate help.
Calls that look local, from wherever you are
The core feature is outbound calling with a local caller ID. When you call someone in the 305 area code, for example, their phone shows a 305 number even if you are nowhere near Miami. The number is not blocked, which is the point: the developer's argument is that people are more likely to pick up a local number on the first attempt than an unknown or withheld one.
The developer notes that the data used per call is small, while also pointing out that your carrier's data fees still apply.
Your personal number stays out of the exchange. That single design choice is what separates this from simply dialing from a department phone, and it is the reason the app exists in the first place.
Callbacks that arrive as notifications
The second half of the design handles what happens when someone calls back. Instead of ringing the officer directly, the system answers with a menu: press 1 to request a callback, or press 0 to reach a dispatcher.
When a citizen chooses the callback option, the officer gets a push notification rather than an incoming call. For anyone who has been burned by a 2 a.m. callback, that shift from a ringing phone to a notification is the most useful part of the app.
The notification also gives the officer a moment to decide whether the callback is worth making right then, which is a small thing that adds up over a week of outreach.
What the Professional tier adds
The free version covers the basics: calling citizens from local numbers, receiving callback requests and pointing people toward dispatch when they need immediate help. A Professional subscription adds several things on top. Subscribers can set their outbound caller ID to read "LAW ENFORCEMENT" instead of a number, see the citizen's caller ID when a callback request comes in, and have the app send an automatic follow-up text message after a call.
The fourth subscription benefit is record keeping. Call records are retained for as long as the subscription stays active, which is the kind of thing that matters to an agency that needs a paper trail of its outreach. Whether that trade-off is worth the cost depends on how much an individual officer or department values the caller ID label, the follow-up messages and the retained history.
The app is free to download and carries no ads. It does offer in-app purchases, which is where the Professional subscription sits. The developer's own note on calling costs is worth repeating: calls use data rather than cellular minutes, and any data charges come from your carrier.
How it compares with ordinary workarounds
Most officers who need to reach citizens today use whatever phone the department issues, a personal cell or a desk line. Each has a drawback. The app's pitch is that a local number solves the recognition problem while a data connection solves the location problem.
A general VoIP or business calling service is another category worth weighing. The dispatcher routing in particular is a law enforcement concern rather than a general business one.
A third option is simply accepting the miss rate and following up by other means. That costs nothing and requires no new tool, but it also means the same calls go unanswered next week. The app is a bet that a local number and a callback queue will change that pattern, and the developer's framing of the problem is plausible.
A narrow tool with a clear job
10-21 Police Phone does one job and does it in a specific way. It gives officers a way to place citizen calls from local numbers without exposing a personal line, and it turns return calls into notifications that can be answered on the officer's schedule. The Professional tier adds a caller ID label, visible citizen caller ID on callback requests, automatic follow-up texts and retained call records.
The app has been downloaded more than 100,000 times and holds a 2.8 average from 614 ratings, which suggests a mixed reception among the people who have tried it. That is a signal worth weighing, though ratings on a specialized tool like this often reflect expectations shaped by general-purpose calling apps rather than the specific workflow it targets.
If you are an officer or agency that regularly phones citizens and wants those calls answered without handing out a personal number, this is a purpose-built option with a free starting point. For the specific problem it names, it is a reasonable thing to install and try.
The short verdict
A focused outreach tool for officers who want citizen calls answered from local numbers without exposing a personal line.

10-21 Police Phone: frequently asked questions
What does 10-21 mean in this app?
It is the radio code for making a phone call, and the app is built around that action. The name signals that the tool is about placing calls rather than dispatching or emergency response. The developer positions it as a way to reach citizens and route them onward when a situation needs a dispatcher.
How do citizens reach an officer if they call back?
The call is answered with a menu rather than ringing the officer. Callers can choose 1 for a callback or 0 for a dispatcher. The dispatcher option connects to a non-emergency number that the officer provides.
Does the app use cellular minutes?
Because calls go through VoIP, they use data rather than talk minutes. Each call uses only a small amount of data. Your carrier's data fees may still apply depending on your plan.
What do Professional subscribers get?
The subscription adds four things on top of the free features. Subscribers can set outbound caller ID to read "LAW ENFORCEMENT", see the citizen's caller ID on callback requests, send an automatic follow-up text message, and keep call records for as long as the subscription is active. The app is free to download and offers in-app purchases.
