With U.S. Customs and Border Protection (CBP) stepping up inspections of electronic devices at ports of entry, many travelers—whether U.S. citizens, permanent residents, or foreign visitors—are reassessing how they manage digital privacy when crossing the border. Recent news coverage and increased scrutiny have led some to consider traveling with burner phones. But do such tactics truly safeguard your personal information, and what are the legal and practical implications?

Growing Device Inspections: Why Now?

In the past two years, CBP has ramped up inspections of electronic devices as part of broader efforts to tighten border security. According to recent data from the Department of Homeland Security (DHS), searches of electronic devices at U.S. borders increased by more than 20% in 2024 compared to the previous year, a trend fueled partly by political priorities and heightened national security concerns. Both U.S. citizens and foreign nationals are subject to these searches, which do not require a warrant at the border because of longstanding ‘border search exceptions’ to constitutional protections.

The government justifies these searches as critical for identifying security threats, smuggling, or potential criminal activity. CBP policies allow agents to perform basic device searches—including reviewing texts, photos, call logs, and sometimes even deleted files—without any suspicion. In certain cases, so-called ‘advanced searches’ can access encrypted data if agents believe there is a valid reason, though these are less common. Legal experts warn the trend marks a significant shift in the landscape of border privacy.

Legal Landscape: Burners and Your Rights

Bearing a burner phone—a basic or secondary device with minimal personal information—has quickly become a topic of interest among privacy advocates and travelers alike. Esha Bhandari, deputy director of the American Civil Liberties Union (ACLU) Speech, Privacy, and Technology Project, confirms that there are no legal restrictions against using a burner device. “Your phone does not need to contain your entire digital footprint to enter the country,” said Bhandari. The government itself contends that travelers have the agency to decide what data they bring.

However, privacy and digital rights organizations like the ACLU and the Electronic Frontier Foundation (EFF) argue that modern devices store a vast amount of sensitive personal information, making unwarranted border searches uniquely intrusive compared to traditional luggage checks. Multiple court cases are challenging the scope of border searches, but for now, device inspections remain broadly permissible—especially for noncitizens, whose legal rights at the border may be more limited.

Corporate and Institutional Guidance

As media reports of detainments and deportations linked to social media posts or device contents have circulated, major Canadian banks and universities have advised staff and executives to either avoid U.S. travel or to bring sanitized or burner devices. This comes amid reports of travelers facing long interrogations, device confiscations, or even entry denials due to content found on their phones or laptops.

Increasingly, business travelers, journalists, and those with sensitive professional responsibilities are adopting burner phone protocols. The rationale? If a device contains only travel reservations, essential contacts, and none of the sensitive documents, emails, or photos stored on one’s primary phone, any border search is far less invasive.

Should You Travel With a Burner Phone?

Deciding whether to travel with a burner phone is ultimately a personal risk assessment. Those who handle sensitive information for work—or who are concerned about privacy or their digital footprint being scrutinized—may find it worthwhile. For others, especially those with uncomplicated travel profiles, careful data minimization on a primary device may suffice.

It is worth noting that while U.S. citizens and lawful residents have the right to re-enter the country, refusing a device search can result in the device being confiscated for weeks or months. Foreign nationals, especially those without visas, may face greater risks, including being denied entry. The border environment “carries unavoidable risk,” as Bhandari points out, so travelers should make an informed choice based on their personal circumstances.

Best Practices to Protect Your Data at the Border

• Turn off biometric unlock features: Disable fingerprint or facial recognition before your journey. While legal precedent varies, agents may attempt to use biometrics to unlock your device. A strong passcode is best.
• Log out of all apps and accounts: Social media, email, banking apps, and cloud storage should all be signed out to reduce data exposure during a device search.
• Minimize local storage: Move sensitive files, photos, and documents to secure cloud storage and wipe them from your device. Ensure the device only contains what is absolutely necessary for your trip.
• Enable airplane mode and disconnect from networks: This makes it harder for agents (or hackers) to access information remotely or accidentally sync new data during a search.
• Bring only essential devices: Consider leaving your primary phone, work laptop, or backup drives at home, unless absolutely necessary for travel.
• Consult with IT or legal experts: If you are traveling on business or with sensitive intellectual property, ask your company or organization for official guidance before departure.

Recent Developments and Case Examples

Concrete examples highlight this issue’s complexity and stakes:

• March 2025: A Harvard-affiliated doctor was deported after agents identified old images on her phone deemed controversial, despite her cleared visa status. Incidents like this have increased calls for clearer, fairer guidelines on device inspection and retention at borders.
• April 2025: Canadian businesses caution staff about potential border scrutiny, even encouraging use of burner phones.
• Ongoing: Lawsuits filed by advocacy groups challenge the constitutionality of suspicionless device searches, though appellate courts continue to uphold broad CBP powers for the time being.

Bottom Line: Plan Ahead, Travel Smart

Travelers crossing U.S. borders face new realities in digital privacy. Using a burner phone is legal and may reduce a traveler’s risk of invasive scrutiny, but no solution is foolproof. The best protection is planning ahead: minimize device data, strengthen security settings, and understand your rights.

As device inspections remain a central part of border security, staying informed and proactive is essential for all international travelers. When in doubt, consult with legal counsel or privacy advocates before departure and tailor your digital footprint to your comfort level.
