Does the 4th Amendment apply to border searches?

Yes, the Fourth Amendment applies to border searches, but there's a significant "border search exception" that allows Customs and Border Protection (CBP) to conduct routine searches of people and belongings without warrants, probable cause, or reasonable suspicion, due to reduced privacy expectations at the border and national security interests. While this applies to physical searches, searches of electronic devices (like phones) are more complex, with courts recognizing a greater privacy concern, though warrantless searches are still common.
