Border Agents Can Search and Seize Your Phone at US Airports — Here's What to Know
CBP's Border Search Authority
When Janette Zahia Corcelius returned home to Minnesota from a three-week trip to Europe in late April, she had no reason to expect trouble. But at Minneapolis-St. Paul International Airport, customs agents detained her, searched her luggage twice, confiscated political literature she had purchased abroad, and seized her phone—a device she still hasn't gotten back, according to a federal lawsuit.
The incident highlights a controversial power that U.S. Customs and Border Protection (CBP) agents have long held: the authority to search and confiscate electronic devices at international border crossings without a warrant or any particularized suspicion of wrongdoing.
Legal Framework
Border search doctrine, rooted in the Fourth Amendment's exception for searches at the border, gives CBP broad latitude to inspect travelers' belongings—including digital devices—for contraband, weapons, or materials that might pose a national security threat. Unlike searches in the interior of the United States, border searches don't require probable cause or a warrant.
The agency's policies technically require that device searches be "reasonable" and related to border enforcement, but critics argue the standard is vague and easily abused. CBP reports conducting tens of thousands of device searches each year, a number that has grown as travel has increased and as officials have gained more sophisticated tools to examine data on phones and laptops.
What This Means for Travelers
For international travelers, the practical reality is that crossing a U.S. border means surrendering a degree of privacy. CBP agents can ask to see your phone, copy data from it, or keep it for further examination. U.S. citizens generally cannot be denied entry to the country, but they can still be subjected to invasive device searches and face delays.
Experts advise travelers who want to protect sensitive data to consider using secondary devices or cloud-based storage rather than carrying everything across borders. Encryption can offer some protection, but CBP has tools capable of defeating some protections, and travelers can be compelled to unlock devices if asked.
A Growing Concern
Civil liberties groups have raised alarms about the expanding use of border device searches, arguing they chill First Amendment activity and discriminate against travelers from certain backgrounds. The lawsuit filed on behalf of Corcelius alleges that her political literature and activism made her a target for heightened scrutiny.
As digital privacy becomes increasingly central to daily life, the intersection of border security and personal data rights remains a flashpoint for legal and policy debates.
