Serving T-Mobile in Sacramento, California
T-Mobile USA, Inc. is the second-largest wireless carrier in the United States by subscriber count and one of the most frequently served telecom defendants in California. Operating in its current U.S. form since 1994 and headquartered in Bellevue, Washington, T-Mobile serves tens of millions of California consumers across wireless voice, data, prepaid (Metro by T-Mobile), and home internet products. Following the 2020 merger with Sprint, T-Mobile absorbed Sprint Communications Company L.P. and related subsidiaries — relevant to pre-merger claims.
Plaintiffs and attorneys serve T-Mobile for TCPA robocall and text message class actions, billing and consumer protection disputes, wage-and-hour and PAGA actions, wrongful termination and employment claims, data breach class actions (the 2021 and 2023 incidents generated significant litigation), and subpoenas for subscriber records in civil and criminal matters. The correct California entity for almost all current matters is T-Mobile USA, Inc.; pre-2020-merger Sprint matters may still name Sprint Communications Company L.P.
Like most large California corporations, T-Mobile uses a designated registered agent to accept service of process — meaning the legally required service goes to the agent’s Sacramento office, not directly to a company store, office, or corporate facility. SACRPS handles registered agent service of process every day. We are licensed and bonded with Sacramento County (Reg #024-027), we know exactly who accepts service at every major California registered agent office, and we deliver court-ready proof of service the same day in most cases.

Frequently Asked Questions
Who is T-Mobile’s registered agent in California?
T-Mobile USA, Inc.’s California registered agent is CSC (Corporation Service Company), located at 2710 Gateway Oaks Drive, Suite 150N, Sacramento, CA 95833. We serve CSC routinely — see our CSC registered agent page for full details. (Always verify the current agent on file at the California Secretary of State business search before serving — agents can change.)
Can I serve T-Mobile at a local office or location instead?
The most reliable way to serve T-Mobile is through their registered agent in Sacramento. California law (CCP §415.10 / §416.10) allows service on a corporation only at specific designated persons or locations, and attempting service at a retail store, branch office, or local facility may not satisfy the legal requirements — risking defective service that gets thrown out. Using the registered agent avoids that risk entirely. The cost is the same either way ($85 flat for registered agent service).
How fast can you serve CSC?
Same-day in most cases. The CSC office at 2710 Gateway Oaks is open standard business hours, and we can typically pick up your documents and serve them within a few hours of receiving them. Rush jobs are no problem.
What types of legal documents do you serve on T-Mobile?
Every type — subpoenas for subscriber records, call detail records, and text message logs (SDT subpoenas are a high-volume category), summons and complaints, TCPA and robocall class actions, data breach class action notices, wage-and-hour and PAGA complaints, and consumer billing disputes. TCPA and subscriber records are the two highest-volume categories we handle.
What is the price difference between registered agent service and direct service?
Registered agent service is a flat $85 — that’s the recommended approach for almost all registered agent service. Direct service (when appropriate) is process serving and uses our tiered pricing: Standard $99 (5 days), Expedited $150 (3 days), Rush $175 (24 hours). For the vast majority of cases, registered agent service is the right choice and the cheaper option.
