Serving Requests for User Data On Behalf of Defendants in Criminal Proceedings in the U.S. on Meta

UPDATED JUL 7, 2026

This page provides information for an individual or an attorney seeking user data from Meta Platforms, Inc. (“Meta”) on behalf of a defendant in a criminal proceeding in the U.S. This information may change at any time. The information on this page should not be construed as a waiver of any of Meta's rights or objections to any subpoena it receives.

You can serve Meta with legal process on behalf of a defendant in a criminal proceeding through the appropriate office of Meta’s registered service agent, Corporation Service Company (or “CSC”).

The CSC office in California is located at the following address:

Corporation Service Company

2710 Gateway Oaks Drive, Suite 150N

Sacramento, CA 95833

If you would like to serve Meta with legal process through CSC outside of California, you may be able to find other addresses for CSC by searching for Meta Platforms, Inc., on the website of the Secretary of State for other states.

We prefer that service be made through CSC because service on Meta through CSC will ensure the most efficient handling of the request.

If you want to serve Meta by other means, check the applicable laws, rules, and regulations governing your legal request.

Please note that requests must specifically identify the Meta service at issue (e.g., Facebook, Instagram) and identify the accounts at issue by Uniform Resource Locator (“URL”), email address, or other appropriate unique identifier. Requests to identify users by real names or IP addresses may be declined.

Where Can I Obtain Information About My Own Account?

If you are a user seeking your own account data, please see here for information on how to download your Facebook account information and here for information on how to download your Instagram account information. Using these tools will allow you to obtain your account data much faster than issuing a subpoena to Meta.
