Stored Communications Act (SCA)
Definition
Part of the US Electronic Communications Privacy Act (18 U.S.C. 2701-2712) that governs government access to stored electronic communications and data. It sets out the three-tier process: subpoena for subscriber records, court order for metadata, and search warrant for content. Many non-US jurisdictions have equivalent statutes with similar threshold structures.

Common questions
Why does the SCA require a warrant for content but only a subpoena for subscriber records?+
The tiered structure reflects an escalating privacy interest: basic account details like a name or IP address are treated as less sensitive than the actual content of communications, so the law sets a correspondingly higher evidentiary bar, a full warrant, before a provider must hand over message content.
Does the Stored Communications Act apply outside the United States?+
It only directly governs US-based providers and US legal process, but many other countries have built comparable tiered-access statutes for stored communications, and cross-border requests often route through mutual legal assistance treaties when a foreign provider is involved.
