Can certified mail be put in mailbox

According to the United States Postal Service (USPS), certified mail can be sent through a mailbox, but there are some specific requirements and considerations to keep in mind:

  1. Certified Mail with Return Receipt Requested: If you're sending certified mail with a return receipt requested, you must hand the item to a postal employee or deposit it in a mailbox that is designated for certified mail. This is because the return receipt requires a signature from the recipient, which can only be obtained through a postal employee or a designated mailbox.
  2. Certified Mail without Return Receipt Requested: If you're sending certified mail without a return receipt requested, you can deposit it in a mailbox. However, you should ensure that the mailbox is a designated mailbox for certified mail, and you should affix the correct postage and complete the certification form (PS Form 3800) before depositing it.
  3. Mailbox Requirements: The mailbox must be a designated mailbox for certified mail, which is typically marked with a sign or a sticker indicating that it is a certified mail mailbox. You can also check with your local post office to confirm if a particular mailbox is designated for certified mail.
  4. Postage and Certification: Regardless of whether you're sending certified mail with or without a return receipt requested, you must affix the correct postage and complete the certification form (PS Form 3800) before depositing it in the mailbox.

In summary, certified mail can be sent through a mailbox, but you must ensure that the mailbox is designated for certified mail, and you must follow the proper procedures for affixing postage and completing the certification form.
