Can Airport Security Check Your Phone

Airport security agencies around the world can search electronic devices including phones at international borders and checkpoints. The U.S. Transportation Security Administration (TSA) and U.S. Customs and Border Protection (CBP) have explicit authority to inspect devices under the Fourth Amendment border search doctrine, and they routinely do so at airports like Hartsfield-Jackson Atlanta and Los Angeles International. In the European Union, border guards under Regulation (EU) 2019/1177 can also examine phones and laptops without a specific suspicion, and similar powers exist in Canada, the UK, and Australia.

In 2024, CBP reported conducting tens of thousands of device searches at U.S. ports of entry, with phones being the most common target. The agency can copy data, unlock devices using passcodes or biometrics, and retain devices for days during forensic analysis. In the EU, the European Data Protection Supervisor has noted that border searches of devices increased alongside digital travel pre-screening programs, and Interpol supports cross-border sharing of device data when linked to security alerts.

What Data Can Be Accessed and Shared

During a phone search, officers can view contacts, messages, photos, call logs, emails, and installed apps. They may also extract data using tools like Cellebrite or GrayKey, which can bypass encryption on some devices. The U.S. Department of Homeland Security states that such searches help identify threats, locate missing persons, and detect illicit content, while the European Commission notes that border authorities must comply with EU data protection rules when accessing personal information.

Data from phone searches can be shared with other agencies and partner countries. In the U.S., CBP shares device data with the FBI and other intelligence bodies under the DHS Information Sharing Environment. In the EU, the Schengen Information System allows border and police authorities across member states to access alerts linked to device data, and the Five Eyes intelligence alliance facilitates broader sharing among the U.S., UK, Canada, Australia, and New Zealand.

How to Protect Your Phone at Airport Security

You can reduce risk by enabling full-disk encryption, using strong alphanumeric passcodes instead of biometrics at checkpoints, and turning off your device before reaching the security line. The Electronic Frontier Foundation recommends backing up data and removing sensitive files before travel, while the U.S. CBP advises travelers to ensure devices are unlocked and powered on to avoid delays or further inspection.

Some travelers use privacy-focused tools such as VPNs, encrypted messaging apps like Signal, and secure cloud storage to limit exposure during a search. The U.S. Supreme Court ruled in Riley v. California that police generally need a warrant to search a phone's digital contents, but border searches remain an exception under current law, as confirmed by the Department of Justice and referenced by the ACLU on its border privacy pages.
