Do Border Searches of Cell Phones Require a Warrant in Florida?

Can border agents search your cell phone without a warrant? In Florida, controlling federal court decisions generally allow these searches. In United States v. Smith, a federal district judge in New York reached a different conclusion in 2023, but that ruling did not establish a nationwide warrant requirement. Later decisions have rejected its approach.

The Case at Hand

In United States v. Smith, the defendant, Jatiek Smith, was detained by Customs and Border Protection agents upon his return to Newark Airport from Jamaica. The agents forced Smith to turn over his cellphone and its password, then proceeded to manually review the phone and create an electronic copy of its contents, all without a search warrant. Weeks later, the government applied for and obtained a search warrant to review the electronic copy.

Smith challenged the search through a motion to suppress, asking the court to exclude the evidence obtained from his phone. Although the judge found the search unconstitutional, he denied suppression under the good-faith exception. A finding that a search violated the Fourth Amendment does not always mean the resulting evidence will be excluded.

The Fourth Amendment and Cell Phones

In Riley v. California, the Supreme Court held that police generally need a warrant to search digital information on a cell phone seized during an arrest. The Court stressed the amount and sensitivity of the information phones contain. Riley addressed searches incident to arrest; it did not decide the rules for border searches.

In Riley, the Supreme Court recognized that cell phones contain a vast amount of personal and private information. This makes the search of a cell phone far more intrusive than the search of a person’s pockets or bag.

How Later Courts Have Treated Smith

In United States v. Alisigwe, decided September 17, 2026, the Second Circuit expressly rejected Smith’s warrant reasoning and held that the manual border searches before it required neither a warrant nor reasonable suspicion. The court left open whether some forensic searches might require reasonable suspicion. Smith should therefore be read as a district court decision whose warrant rule was later rejected by the governing appeals court.

The Current State of the Law

For travelers entering through Miami, the key precedent comes from the Eleventh Circuit, which covers Florida. In United States v. Touset, the court held that the Fourth Amendment does not require reasonable suspicion for forensic searches of electronic devices at the border. It also reaffirmed that these searches do not require a warrant or probable cause.

Courts elsewhere differ on the suspicion required for certain searches and the permissible scope of those searches. Travelers should not assume that the warrant rules governing an ordinary police search of a phone also apply at an international border.

Conclusion

Smith shows how courts have wrestled with the privacy concerns raised by border searches of cell phones. For travelers entering through Florida, however, Eleventh Circuit precedent permits broad warrantless searches. Whether a particular search can be challenged depends on its facts and the law that governs it.
