What is a USPS Certificate of Mailing?

The USPS Certificate of Mailing is a document that proves that an item was mailed on a specific date. It does not confirm the delivery date, gives proof of shipping, or provide insurance against loss. Only the date the package was mailed is listed on this certificate.

USPS Certificate of Mailing

You’ll need the mailing certificate if you ever need an official document to back yourself up or proof that you sent mail to someone if the package gets lost or stolen.

You can only purchase a certificate of mailing when you go to the post office to send out a mailer. However, not all USPS services provide you with a certificate. The following USPS services offer USPS Certificate of Mailing:

  • First-Class or Priority Mail
  • First-Class Package Service-Commercial (except for parcels mailed at commercial plus prices)
  • Priority Mail
  • USPS Retail Ground
  • Bound Printed Matter
  • Library Mail
  • Media Mail

USPS provides different certificates of mailing depending on your requirements. And each certificate has its form. The available forms include PS Form 3817, PS Form 3665, PS Form 3877, PS Form 3606, and PS Form 3606-D.

When Should You Use a USPS Certificate of Mailing?

While most postal service providers such as the USPS guarantee accurate delivery of mails, there is always the possibility of an error.

Your mailer could be misplaced, damaged, or accidentally delivered to the wrong address. In such a situation, a certificate of mailing can be a lifesaver from unnecessary issues, especially if the mail is urgent or timely. For example, a certificate of mailing may be required in the following circumstances:

Mailing checks

Security is a significant issue with sending checks via postal mail, so you shouldn't take any risks. Instead, obtain a certificate of mailing when you ship it if the package was never received.

Mailing tax forms

Tax forms are timely documents. If you fail to send them within the stipulated time, you could get penalized. Thus, you need to obtain proof of mailing should the tax forms get lost in the mail.

If you send out a government form or legal document and it doesn't get delivered, proof of mailing can be helpful.

Mailing time-sensitive documents

It can be frustrating to worry about missing a deadline when sending a timely document. The mail can be delayed at times, but you can establish that you shipped it in time with proof of mailing.

How Much Does a USPS Certificate of Mailing Cost?

Every year, the cost of getting a certificate of mail varies. However, it is very affordable to use the USPS Certificate of Mailing. As of 2021, the price was $1.55 to use this service. But, the price varies depending on whether you buy the certificate with or without an individual article.

If you use an individual article with a Firm Mailing Book, you will get it at a more affordable price.
