Certified mail is a secure way to send important documents and packages while receiving proof of delivery. Whether you're sending legal paperwork, contracts, or time-sensitive notices, this guide will walk you through the process of sending certified mail effectively.

What is Certified Mail?

Certified mail is a service offered by postal services that provides proof of mailing and delivery. It includes a tracking number and requires a signature upon receipt, ensuring that your document reaches the intended recipient securely.

Why Use Certified Mail?

Commonly used for:

  • Legal and court documents

  • Business contracts

  • Government correspondence

  • Tax documents

  • Notices of eviction or termination

  • Any document requiring proof of delivery

How to Send Certified Mail

Step 1: Prepare Your Document or Package

Ensure your document is properly sealed in an envelope or your package is securely wrapped.

Step 2: Visit the Post Office

Certified mail services must be processed at a post office. Locate the nearest post office and bring your mail item with you.

Step 3: Fill Out the Certified Mail Form (PS Form 3800)

Request PS Form 3800 from the postal worker or pick it up in advance. This form includes a unique tracking number and serves as proof of mailing.

Step 4: Choose Additional Services (Optional)

You can enhance security with additional services like:

  • Return Receipt (PS Form 3811): Provides a physical or electronic proof of delivery, including the recipient’s signature.

  • Restricted Delivery: Ensures only the recipient can sign for the mail.

  • Certified Mail with Electronic Return Receipt: Offers digital confirmation of delivery.

Step 5: Pay for Postage

Certified mail rates depend on weight, size, and additional services chosen. The base fee for it is around $4.35 (excluding postage). Adding a return receipt costs an additional $3.70 for electronic or $4.90 for a physical receipt.

Step 6: Get Your Receipt & Tracking Number

After payment, you will receive a receipt with a tracking number. Use this number to monitor the status of your certified mail online.

Step 7: Confirm Delivery

Once the recipient receives the mail, you will receive proof of delivery via email or a physical return receipt, depending on your selected options.
