Certified Mailing Service in Sacramento
Not every legal document requires a process server to knock on someone’s door. In California, certain documents can be legally served by certified mail — and in many cases, it is the most efficient and cost-effective option. Small claims filings, specific family law documents, and other papers authorized for mail service under the California Code of Civil Procedure can all be served this way.
What Is Certified Mailing for Service of Process?
Sacramento Registered Process Server handles certified mailing for service of process at a flat rate of $45. We prepare the mailing, send your documents via USPS certified mail with return receipt requested, track delivery, and provide a completed Proof of Service by Mail that is ready for court filing. You do not have to stand in line at the post office, fill out certified mail forms, or worry about whether the paperwork meets court requirements.
If you are not sure whether your documents can be served by mail, we can help you determine the right method. Some documents require personal service — we handle that too. But when mail service is appropriate, this is the fastest, simplest, and most affordable way to get it done. For small claims cases in particular, certified mailing is often the standard method.

How It Works
Step 1 — Submit Your Documents
Complete our online intake form and upload the documents that need to be mailed. Provide the recipient’s name and mailing address. Let us know the type of case so we can confirm that certified mail service is appropriate for your documents.
Step 2 — We Handle the Certified Mailing
We prepare your documents for mailing, send them via USPS certified mail with return receipt requested, and track the shipment. You receive the tracking number so you can monitor delivery status in real time. We handle all the postal forms and packaging.
Step 3 — You Receive Proof of Service by Mail
Once the mailing is complete, we prepare a Proof of Service by Mail documenting the date of mailing, the documents sent, the recipient’s address, and the certified mail tracking number. This proof is court-ready and delivered to your inbox. If you need the original filed with the court, we offer court filing for an additional $30.
