Can Police Search or Track Your Phone in Indiana?
In most cases, Indiana police need a search warrant to look through the contents of your phone, even after an arrest. Indiana law also says police may not force you to give up your passcode without a warrant, and it generally requires a court order before police track a phone's location in real time. There are exceptions, including consent and emergencies. Police may also be able to get some records from your phone company or app provider without ever touching your phone.
Key points
A search of the data on your phone generally requires a warrant (Riley v. California, U.S. Supreme Court, 2014).
You can decline to consent to a phone search. In Indiana, a person in custody generally must be told of the right to talk with a lawyer before giving valid consent to some searches, and the Indiana Court of Appeals has applied that rule to a general search of a cell phone.
Indiana law bars police from compelling your passcode without a warrant (IC 35-33-5-11), and the Indiana Supreme Court has held that forcing a suspect to unlock a phone violated the Fifth Amendment on the facts of that case.
Real-time location tracking generally requires a court order based on probable cause (IC 35-33-5-12).
Do police need a warrant to search your phone?
Usually, yes. In Riley v. California (2014), the U.S. Supreme Court held that police generally must get a warrant before searching the digital information on a cell phone seized during an arrest. The Court recognized that case-specific exceptions, such as a true emergency, may still apply.
A warrant must be supported by probable cause and must describe what may be searched. The Indiana Constitution adds its own protection. Article 1, Section 11 bars unreasonable searches and seizures, and Indiana courts judge reasonableness by weighing how strongly police suspected a violation, how intrusive the search was, and how great the law enforcement need was (Litchfield v. State, Indiana Supreme Court, 2005).

What if you agree to let police look at your phone?
If you voluntarily consent, police do not need a warrant. You have the right to say no. A clear, calm statement such as "I do not consent to a search of my phone" is enough. Do not physically resist an officer.
Indiana has an added protection for people in custody. Under Pirtle v. State (Indiana Supreme Court, 1975), a person in custody generally cannot give valid consent to certain searches unless the person was told of the right to consult a lawyer first. The rule has traditionally applied to searches of homes and vehicles. In Posso v. State (2021), the Indiana Court of Appeals applied it to a general search of a cell phone. The rule does not usually apply during an ordinary traffic stop when the person is not in custody.

Can police make you unlock your phone?
Indiana law says police may not compel a person to provide a passkey, password, or keycode to an electronic device without a valid search warrant issued by a judge (IC 35-33-5-11).
Even a warrant may not be the end of the question. In Seo v. State (2020), the Indiana Supreme Court held that forcing a suspect to unlock her iPhone would violate her Fifth Amendment right against self-incrimination. The State had not shown that it already knew what files were on the phone. That case involved a passcode. The Indiana Supreme Court did not decide whether police may force someone to unlock a phone with a fingerprint or face scan.
If police ask for your passcode, you may say that you want to speak with a lawyer before answering. Do not delete data or reset the phone. Destroying or altering potential evidence can lead to separate charges, such as obstruction of justice.
Can police read your text messages without your phone?
Sometimes. Police do not always need the phone itself. They may seek records from phone carriers, app providers, and cloud services.
Message content: Under the federal Stored Communications Act, police generally need a warrant to get the content of recent messages from a service provider (18 U.S.C. 2703).
Account and subscriber records: Basic information, such as the name on an account, billing details, and assigned phone numbers, can often be obtained with a subpoena. Some other records can be obtained with a court order.
Indiana orders: Indiana judges may order service providers to disclose electronic user data, including data stored outside Indiana, when the provider is an Indiana company or does business with Indiana residents (IC 35-33-5-11).
The other person's phone: Messages you sent are also stored on the recipient's device. If that person shares them or consents to a search, police may see them that way.

Can police track your phone's location?
Real-time tracking: Indiana law says police may not use a real-time tracking instrument to obtain a cell phone's location without a court order based on probable cause, unless exigent circumstances require immediate action. When police act without an order because of exigent circumstances, they must seek an order within 72 hours (IC 35-33-5-12).
Emergencies: In an emergency involving a risk of death or serious bodily injury, Indiana law requires providers to disclose location information to law enforcement on request. Police must then seek a warrant or court order within 72 hours (IC 35-33-5-15).
Location history: In Carpenter v. United States (2018), the U.S. Supreme Court held that police generally need a warrant to obtain historical cell-site location records. The Court described the decision as narrow, and some questions, such as records covering shorter periods, remain open.
What happens if police search your phone illegally?
If a search violated the Fourth Amendment or the Indiana Constitution, a defense lawyer can ask the court to suppress the evidence, meaning the prosecution could not use it at trial. Courts decide these motions based on the specific facts, and there are exceptions that can allow evidence to come in. Whether a phone search was lawful is often a key question in a criminal case.
What to do if police ask for your phone
Stay calm and do not resist. Physical resistance can lead to additional charges.
Say clearly that you do not consent to a search of your phone.
Ask whether you are free to leave. If you are, you may calmly leave.
Ask for a lawyer if you are arrested or questioned, and do not provide your passcode before speaking with one.
Do not delete messages, photos, or apps. Deleting potential evidence can create new legal problems.
Write down what happened as soon as you can, including the officers' names, the time, and what was said.
