The Rise of Border Device Inspections

In recent years, the U.S. Customs and Border Protection (CBP) agency has stepped up inspections of electronic devices, including smartphones and laptops, at airports and land crossings. This uptick follows policy updates aimed at enhancing national security and intercepting contraband. According to CBP’s 2023 Electronic Device Search Report, more than 40,000 device searches were conducted at U.S. points of entry last year—a figure that has nearly doubled since 2017.

The scope of these searches is broad: CBP officers can examine files stored directly on a device, including photos, text messages, and deleted folders, without obtaining a warrant. In more complex cases, such as when criminal activity is suspected, an advanced search (requiring reasonable suspicion) may be performed—potentially extracting data from apps, downloads, and even social media accounts.

What Is a Burner Phone and Why Do Travelers Use Them?

A burner phone is a low-cost prepaid mobile phone that can be used temporarily and later discarded. Typically, these devices store minimal or no personal data, making them ideal for travelers seeking to minimize digital footprints during international trips.

Employment of burner phones has become more common not only among journalists and activists concerned about data security, but also among business travelers who handle sensitive company information. In fact, several Canadian corporations made headlines in early 2025 by recommending that their executives travel to the U.S. exclusively with burner phones, following concerns about intellectual property risks and possible data breaches at U.S. border crossings (Detroit News).

Is It Legal to Carry a Burner Phone Across U.S. Borders?

Legal experts are unanimous: there is no law prohibiting travelers from using or carrying a burner phone at the U.S. border. Travelers—regardless of whether they are U.S. citizens, permanent residents, or foreign visitors—are not required to provide any particular type or amount of digital information to border agents.

As Esha Bhandari, deputy director of the ACLU’s Speech, Privacy, and Technology Project, explains: “There’s no legal barrier to traveling with only certain digital information or with an empty device. The government has even argued that if travelers can control what they bring, they should be able to travel without personal material on their device.”

Court rulings dating as far back as 2018 have recognized that electronic devices can legally be subject to search at borders under the so-called ‘border search exception.’ This means CBP does not need a warrant to inspect your phone. Nevertheless, the law does not specifically outlaw the use of secondary, minimal-data devices—giving travelers the right to choose what to carry.

Pros and Cons: Should You Travel with a Burner Phone?

The decision to use a burner phone comes down to a personal risk assessment. Those regularly handling confidential information, such as business executives, journalists, medical professionals, or lawyers, may find it worthwhile to bring a clean device, limiting exposure of client, trade secret, or patient data.

For others, simply removing sensitive data from a primary device or transferring information to encrypted cloud storage may suffice. As Bhandari notes, “No traveler is obligated to have all their personal information on them. But with heightened enforcement, travelers do need to be aware of the risks.”

It’s important to remember: While citizens and permanent residents cannot be denied entry for refusing a device search, their phones may be confiscated for weeks or months. For temporary visitors or non-visa holders, refusal can result in denial of entry.

Recent Trends and Enforcement: What’s Driving the Change?

The Department of Homeland Security continues to expand digital vetting for travelers, including the examination of social media profiles as part of visa applications as of April 2025 (USCIS). Legal analysts argue this increased scrutiny has created a “chilling effect” on freedom of expression, as people self-censor information that could be misinterpreted at the border.

This environment led to well-publicized detainments and even deportations, especially for non-citizen travelers found with content CBP deemed suspicious. According to recent reporting, more than a dozen cases have been flagged in 2025 involving harsh questioning or device inspection based solely on digital content.

Privacy Tips for Crossing the U.S. Border

• Turn Off Biometrics: Disable fingerprint or facial recognition and use a strong passcode instead. Biometric locks can sometimes be more easily bypassed by agents.
• Log Out of Accounts: Log out of email, social media, and banking applications before travel.
• Limit Local Storage: Store non-essential documents and data in encrypted cloud storage rather than on your device.
• Airplane Mode: Disconnect your device from Wi-Fi and cellular networks before inspection to restrict access to live data and accounts.
• Know Your Rights: U.S. citizens and Green Card holders cannot be denied entry, but your device can be held. Foreign nationals may risk refusal of entry.

Implications for International Travelers and Businesses

With the volume and depth of border inspections rising, companies handling proprietary data are re-evaluating travel protocols. The International Association of Business Communicators (IABC) estimates that as many as 30% of large enterprises have revised their electronic device policies for U.S. travel in 2024–2025. These may include issuing ‘travel phones,’ mandatory device encryption, and limiting non-essential travel for certain employees.

As global commerce and professional travel rebound post-pandemic, understanding and mitigating digital privacy risks has become a crucial part of travel planning for executives and everyday travelers alike.
