T-Mobile USA’s California Service Address Is CSC at 2710 Gateway Oaks
T-Mobile USA, Inc. — the post-merger legal entity for T-Mobile’s U.S. operations including the former Sprint business — uses CSC Lawyers Incorporating Service at 2710 Gateway Oaks Drive in Sacramento as its California registered agent. The case mix is heavy on Telephone Consumer Protection Act (TCPA) claims, where T-Mobile is one of the most-sued telecom carriers nationally due to robocall and unsolicited-text exposure. Consumer fraud (billing disputes), wage/hour employment, and breach of contract claims add to the volume.
TCPA’s statutory damages structure ($500-$1,500 per violation) makes the timing of service important — pro se plaintiffs and class-action firms both push for prompt service to lock in the violation date and start the response clock. Sacramento Registered Process Server handles T-Mobile USA serves the same way as any registered-agent service: standard $99 flat next-day, same-day for $25 more, POS-010 next morning.

Frequently Asked Questions
Does Sprint (now part of T-Mobile) use the same registered agent?
Post-merger, Sprint operations are absorbed into T-Mobile USA, Inc. Legacy Sprint contracts and historical claims may still reference Sprint Corporation or related entities — verify the named defendant in your case. For most current litigation, T-Mobile USA, Inc. at CSC is the correct service path.
Can I serve a TCPA class-action notice at CSC?
Yes. Class-action service to T-Mobile USA, Inc. routes through CSC like any other complaint. The notice is served, CSC forwards to T-Mobile’s class-action defense team, and the response follows the standard 30-day timeline.
How does T-Mobile typically respond to robocall claims?
T-Mobile generally answers TCPA cases on the merits within the 30-day response window — often with a denial of consent issues or a removal to federal court for class actions. They don’t ignore TCPA cases; the statutory damages structure makes ignoring impossible.
