Certificate of Mailing

Getting Started

A Certificate of Mailing (COM), also known as USPS Form 3877 or firmbook mailing, provides proof that you mailed an item on a specific date. While it does not provide tracking or delivery confirmation, it serves as a receipt verifying that you sent something through the mail, which can be important in legal situations.

What Is a Certificate of Mailing?

A Certificate of Mailing is a document issued by the United States Postal Service (USPS) that serves as proof that you mailed an item on a specific date. Key points include:

Proof of Sending: It confirms that you presented the mail to the USPS for mailing on a specific date, not that the recipient received it.
No Delivery Details: It does not provide information about when or where the mail was delivered.
Obtaining a Certificate: You can purchase a Certificate of Mailing at the post office when you send your mail.
Legal Situations: A Certificate of Mailing can be important in legal situations where you need to demonstrate that you sent a document on a specific date.

COM Requirements at LetterStream

To use the COM option through LetterStream, your mailings must:

Be sent as a first-class mailing.
Include more than 5 recipients.
Be mailed in a standard-sized envelope (up to 15 sheets of paper per recipient can be included).

If you are sending 5 letters or fewer, certified mail may be a more cost-effective option, as it provides tracking and a signature upon successful delivery.
