Whether you have some experience with Certified Mail or you’re needing to mail a letter with this extra service for the first time, we can all agree that Certified Mail is complex. The forms, options for different mailing needs, changing prices—where do you start? This article will clear things up.

Since its inception in 1955, Certified Mail has become one of the most important and popular extra services offered by the USPS. According to USPS reports, 197 million pieces were sent with Certified Mail in 2016. Now, American citizens and business continue to leverage the Certified Mail extra service to send their most important mail due to its trustworthy and credible reputation.

What is certified mail?

Certified Mail is an extra service that provides the sender with a mailing receipt, tracking history, and, upon request, electronic verification that a mail piece was delivered or that a delivery attempt was made. Certified Mail can be used with both First-Class and Priority Mail, and items sent with this extra service are dispatched and handled in transit as ordinary mail.

When a piece is sent with Certified Mail, the USPS maintains a record of delivery (which includes the recipient’s signature). If the mailer would like a copy of the recipient’s signature, Certified Mail can be paired with the Return Receipt or Electronic Return Receipt extra service.

The hardcopy form used for sending certified mail is PS Form 3800. We’ll talk more about this form in the section on sending certified mail.

Types of certified mail

Depending on your exact mailing needs, Certified Mail can be paired with other extra services for more features. Here’s an overview of your options:

Certified Mail with Return Receipt: Certified Mail is commonly combined with the Return Receipt extra service, which provides the sender with evidence of delivery that includes the recipient’s signature. This comes in the form of PS Form 3811, commonly referred to as the green card. It looks like this:

PS Form 3811 (side 2)

Here’s how it works. The sender attaches the green card to the mail piece before it enters the mail stream. Upon delivery, the carrier has the recipient sign the card, and it is returned to the sender via First-Class Mail.

The form will include three important pieces of information for the sender: the name and signature of the person to whom the piece was delivered, the date of delivery, and information about the recipient’s actual delivery address.

Certified Mail with Electronic Return Receipt: The Electronic Return Receipt does everything the hardcopy Return Receipt does, but, as you guessed, it’s electronic. This means instead of receiving the green card back in the mail, the sender receives a proof of delivery letter (as a PDF) via email attachment by requesting it from the USPS website. The proof of delivery letter includes a digital copy of the recipient’s signature.

The USPS will keep the record for two years from the date of mailing, and after 60 days the record will take longer to retrieve.

There are a couple advantages to this option. It’s cheaper than the hardcopy return receipt, and you don’t have to worry about it potentially getting lost in the mail on its way back to you.

Certified Mail Restricted Delivery: Restricted Delivery allows the mailer to direct delivery of certified mail only to the addressee or an authorized agent. This means the article can be received by only the specified recipient or someone who has been authorized following the USPS guidelines. The Return Receipt or Electronic Return Receipt extra service can be used in conjunction with these extra services if the sender would like to receive a copy of the recipient’s signature.

Certified Mail Adult Signature Required: Adult Signature Required allows the mailer to direct delivery of certified mail only to an adult (an individual who is 21 years of age or older). The Return Receipt or Electronic Return Receipt extra service can be used in conjunction with these extra services if the sender would like to receive a copy of the recipient’s signature.

Certified Mail Adult Signature Restricted Delivery: Adult Signature Restricted Delivery allows the mailer to direct delivery of certified mail only to a specific addressee or authorized agent who is 21 years of age or older. If the specific individual is not 21 years of age or older, the mail piece will be returned to sender. The Return Receipt or Electronic Return Receipt extra service can be used in conjunction with these extra services if the sender would like to receive a copy of the recipient’s signature.

When is it used?

Anyone can send certified mail, but it plays an especially crucial role in business and legal affairs by providing evidence of acceptance and delivery that is admissible in court in the event of a legal case. These cases sometimes rise to the highest levels of the court system.

Certified Mail is commonly used for…

  • Legal notices
  • Government documents
  • Debt collections
  • Foreclosure notices
  • Health care records

How much does it cost?

The Certified Mail extra service costs $3.75 per piece. This fee is in addition to the cost of postage.

For a record of delivery, the Return Receipt extra service costs $3.05 per piece. Comparatively, the Electronic Return Receipt costs only $1.85.

So, if you’re looking to send a letter under one ounce with Certified Mail and the standard hardcopy return receipt (excluding any postage discounts), it will cost $7.38 (that’s $0.58 + $3.75 + $3.05).

How do I send certified mail?

The traditional method for sending certified mail with a return receipt involves multiple hardcopy forms and is a laborious, time-consuming process compared to a streamlined, digital solution like ConnectSuite e-Certify. But, if you insist, here is a step-by-step guide for how to send certified mail with a return receipt the traditional way:

Step 1: Collect PS Form 3800 and PS Form 3811 (green card) from the window clerk at the post office.

Step 2: Fill out PS Form 3800.

Step 3: Fill out both sides of PS Form 3811.

Step 4: Peel the tracking number label off the top of PS Form 3800 and apply it to PS Form 3811 in box 2.

Step 5: Attach PS Form 3800 to the front of your envelope, folding the green strip over the top on the dotted line.

Step 6: Attach PS Form 3811 to the back of your envelope.

Step 7: Meter the envelope, or pay for the postage and fees at the post office. The clerk will stamp PS Form 3800 and give the bottom portion back to you as proof of acceptance. Be sure to file this receipt for record-keeping.

Step 8: As your mail piece makes its way through the mail stream, you can track it by entering the tracking number on the USPS website.

Step 9: When your mail piece is delivered, PS Form 3811 is signed by someone at the recipient’s address, then returned to you via First-Class Mail. Once returned, be sure to file it for record-keeping.

How do I send certified mail with e-Certify?

Creating, tracking, and managing certified mail with e-Certify is much more simple and streamlined than the traditional method. Some of the benefits include…

If you’re already a customer, you can find a more detailed guide on using e-Certify on our Getting Started page. Here’s a brief overview:

Step 1: Create your mail piece by selecting a mailing profile, entering a recipient address, and selecting a page count. If you have many pieces to create, use the file upload for batch piece creation.

Step 2: Print the banner page for your piece and insert it into a window envelope along with the item you are mailing.

Step 3: Submit your mail piece to the USPS in e-Certify, then enter it into the mail stream. When you want immediate proof that your mail pieces have been accepted into the mail stream, print the completed PS Form 3877 provided in e-Certify and bring it to the post office with your mail pieces. There, the window clerk will postmark the 3877 with a round-dated stamp, and it will be returned to you as proof of acceptance.

Step 4: Track your mail piece every step of the way through the mail stream right in e-Certify from the Piece Search page.

Step 5: After your mail piece has been delivered and signed for, you can view and download the electronic return receipt in e-Certify from the Piece Search page.
