Indiana Police Scanner Laws: Penalties, Ownership, and Encryption

Under Indiana police scanner laws, simply possessing a physical police scanner is a Class B misdemeanor unless you qualify for one of several exemptions, while a scanner app on your phone is legal to have unless you use it while committing a crime or trying to avoid law enforcement. The governing statute is Indiana Code § 35-44.1-2-7, and it treats hardware and software very differently.

What Counts as Illegal Use

The statute creates three separate offenses. First, possessing a physical police radio without an exemption is illegal on its own. You don’t need to be listening. You don’t need any criminal purpose. Having the device is the offense.

Second, transmitting on a frequency the FCC has assigned for police emergency use is prohibited for anyone, exemption or not.

Third, possessing or using either a physical scanner or a scanner mobile app while committing a crime, to help commit a crime, or to avoid detection by law enforcement is its own offense.¹

A “police radio” under the statute is any radio capable of sending or receiving on police emergency frequencies that can be installed in a vehicle or carried by a person. Desktop radios designed exclusively for home use are specifically excluded from the definition.¹

Scanner Apps Are Treated Differently From Hardware

This is the part most people get wrong. Indiana separately defines a “police radio mobile application” as any app on a mobile device that lets you listen to police radio traffic. A phone with a scanner app installed is not a “police radio” under the statute, so the simple-possession offense does not apply to it. The app becomes illegal only under the third offense: possessing or using it in connection with a crime or to dodge police.¹

Practically: carrying a physical scanner in your car without an exemption is a crime regardless of intent. Running a scanner app on your phone in the same car is not, by itself, a crime at all.

Penalties

Every offense under the statute is a Class B misdemeanor, which carries up to 180 days in jail and a fine of up to $1,000. The statute has no built-in enhancement, but a scanner charge stacks on top of any underlying offense. Monitoring dispatch during a burglary, for example, means facing the burglary charge and a separate scanner misdemeanor.¹

Who Can Legally Own a Police Scanner

Subsection (b) exempts a broader group than most people expect. These exemptions apply to possession and transmitting only. Using a scanner to further a crime or evade police is still illegal no matter which category you fall into.

Any governmental body and any regularly employed law enforcement officer.
Common carriers for hire and public utility companies whose vehicles are used in emergency service.
Anyone who has written permission from the chief of a law enforcement agency.
FCC-licensed amateur radio operators, provided they don’t transmit on police frequencies. The FCC charges a $35 application fee for new amateur licenses and renewals.²
Anyone using a police radio exclusively in their own dwelling or place of business.
Journalists regularly engaged in newsgathering for a newspaper, wire service, or licensed radio or television station, whose employer has furnished their name to the chief law enforcement officer in the county where the employer’s main office is located.
People in the business of manufacturing or selling police radios.
Anyone using a police radio in the normal course of their lawful business.¹

Two of these deserve extra attention. The journalist exemption isn’t self-certifying. A press badge or freelance status won’t do it: your employer has to register your name with local law enforcement. And if you’re a ham operator, keeping your FCC license accessible when you’re carrying a scanner is the simplest way to resolve any question during a stop.

Listening at Home or in Your Business

Monitoring police dispatch from your living room, garage, or office is legal in Indiana without any license or special permission. The dwelling-and-business exemption covers you, and the statute’s definition of “police radio” reinforces the point by excluding radios designed solely for home use.¹

Federal law lines up with this. Under the Wiretap Act, intercepting radio communications from law enforcement or fire services is not unlawful when those communications are “readily accessible to the general public,” which generally means unencrypted signals on standard public safety frequencies.³

Sharing or Streaming What You Hear

Listening and publishing are legally separate. Section 705 of the Communications Act prohibits intercepting a radio communication and then divulging or publishing its contents without the sender’s authorization, and it also bars using intercepted communications for your own or someone else’s benefit.⁴

A standard violation can bring a fine of up to $2,000, up to six months in jail, or both. If the violation is willful and done for commercial advantage or financial gain, penalties climb sharply, and the statute creates a private right of action so anyone harmed by the disclosure can sue for damages.⁴

The upshot: it is legal to listen to unencrypted police radio at home. Streaming that audio online, especially for money, sits in a legally uncertain area that has never been fully resolved.

Encryption Limits What You Can Actually Hear

Even where the law allows you to listen, you may not be able to. Many Indiana law enforcement agencies now use encryption on some or all of their channels. When a channel is encrypted, no consumer scanner can decode it. The hardware isn’t built to accept encryption keys. The only way to hear encrypted traffic is through an authorized system radio with the correct keys.

The digital standard itself isn’t the obstacle. Modern consumer scanners can handle P25 Phase II traffic. Encryption is a separate layer, and most agencies that use it apply it selectively, leaving a mix of audible and silent channels on the same system. What you can monitor depends less on Indiana’s statute than on which channels your local agencies have chosen to encrypt.
