Any company that has even mail a single letter has probably heard of certified mail. But there is a lot more that goes into Certified Mail than it appears on the surface. We put together a quick guide to help you get the most out of Certified Mail. USPS Certified Mail is one of the USPS’s useful tools. We are going to define certified mail, explain who uses certified mail, explain the difference between Certified Mail and Registered Mail, and the benefits of certified mail.


What is Certified Mail?

Certified Mail is a specialized service offered by the United States Postal Service (USPS) that provides the sender with official proof that an item has been mailed. This service offers a mailing receipt and electronic verification that an article was delivered or that a delivery attempt was made. While Certified Mail itself does not guarantee that the recipient will sign for or accept the mail, it establishes a verifiable record of the mailing event, offering legal and administrative protection to the sender. It’s a valuable tool for sending important documents or items where confirmation of mailing is essential.


Who Uses Certified Mail?

A wide range of individuals, businesses, and legal entities utilize Certified Mail for various purposes. Individuals might use it to send important personal documents like lease agreements, legal notices, or official correspondence. Businesses frequently rely on Certified Mail to send invoices, contracts, legal documents, and notifications requiring proof of mailing. Legal entities, such as law firms and government agencies, often use Certified Mail to ensure proper notification and documentation in legal proceedings and official communications. Essentially, anyone needing a documented record that an item was sent through the mail can benefit from using Certified Mail.


The benefits of using Certified Mail are numerous. It provides legal protection by offering irrefutable proof that an item was mailed on a specific date. This can be crucial in legal disputes or when adhering to contractual obligations. Certified Mail also includes tracking capabilities, allowing the sender to monitor the progress of their mailpiece online and receive confirmation once it has been delivered or a delivery attempt has been made. It also offers peace of mind to the sender, knowing they have a documented record of their mailing and can verify its delivery status, reducing the uncertainty associated with standard mail.

Benefits of Certified mail also include:

  • Proof of Mail
  • Delivery Confirmation
  • Increased Security and Confidentiality
  • Legal Documentation
  • Dispute Resolution
  • P.O Boxes
  • Return Receipt

Proof of Mail

When you use Certified Mail, the United States Postal Service provides you with an official mailing receipt. This receipt serves as tangible evidence that the USPS accepted your mailpiece for delivery on a specific date. Crucially, the receipt is date-stamped by the postal clerk at the time of mailing, making it an official record of when the item entered the USPS system. Additionally, the unique tracking number printed on the receipt allows you to verify this mailing event and track the subsequent progress of your mailpiece through the USPS network. This receipt is often accepted as legal documentation confirming that you sent the item on the date indicated.

Delivery Confirmation

With certified mail, you receive a mailing receipt that serves as evidence of sending the item. This receipt includes the date of mailing and a unique tracking number, providing you with a record of when the item was dispatched.

Increased Security and Confidentiality

Certified mail offers an added level of security for your important documents or materials. It requires the recipient or an authorized person to sign for the item upon delivery, ensuring that it reaches the intended recipient securely.

When sending legal or sensitive documents, using certified mail helps establish a chain of custody. The mailing receipt and delivery confirmation serve as legal proof that the item was sent and received, which can be important for legal and official purposes.

Dispute Resolution

In cases where disputes or disagreements arise regarding the delivery of an item, certified mail provides documentation to resolve such issues. The tracking information and delivery confirmation can be used as evidence in case of any disputes or discrepancies.

Create a Sense of Urgency

When the recipient has to physically sign for Certified Mail, it creates a sense of urgency to open and read the documents. Another advantage of Certified Mail is that it also makes documents look more official and less likely to be found in the junk pile.

P.O. Boxes

USPS Certified Mail is sent to a P.O. box. After that, the delivery notification is found inside the P.O. box.  This instructs the recipient to present the delivery slip to the USPS window clerk.  After signing the delivery receipt, the Certified Mail is given to the recipient.

Return Receipt

In many cases, senders can purchase a Return Receipt for an additional fee. A Return Receipt, also known as a Certificate of Mailing, is a hard copy that shows the recipient’s signature as well as the date and time of each mail-piece delivery. If the sender does not initially purchase the Return Receipt service, you can request a Duplicate Return Receipt for up to two years.

Return Receipt Signatures are now also available in electronic format. Electronic PDF files are quickly replacing hard copies. This is because electronic PDF files are easier to administer, cost less to mail, and are easier to store. Ultimately, this makes them much harder to lose. The PDF format can also easily be emailed or shared. Copies of each Certified Mail transaction including the Electronic Delivery confirmations and Electronic Return Receipt PDF files are stored for 10 years at no additional charge.

Limitations of Certified Mail: What It Doesn’t Guarantee

While Certified Mail offers valuable proof of mailing and delivery tracking, it’s important to understand its limitations. Notably, Certified Mail does not guarantee that the recipient will sign for or accept the mail. The USPS will document the delivery attempt, but if the recipient refuses to sign or is unavailable for multiple attempts, the mail will eventually be returned to the sender. Additionally, Certified Mail does not provide insurance against loss or damage to the contents. If you need financial protection for your mailpiece, you’ll need to purchase separate insurance coverage from the USPS.


These are the most valuable benefits of using Certified Mail from the USPS.

Is Certified Mail Worth the Added Cost?

Deciding whether certified mail is worth the cost ultimately depends on the value you place on added security and peace of mind. While certified mail incurs an additional expense, it offers several benefits that can outweigh the cost. With certified mail, you gain enhanced security for documents containing sensitive information, ensuring they are handled with care throughout the delivery process. The included proof of mailing and delivery confirmation provide legal documentation and peace of mind, especially when dealing with crucial or time-sensitive materials.

By investing in certified mail, you can prioritize the safety and accountability of your important correspondence, making it a valuable option for situations where added security is paramount.
