Can you put unstamped mail in mailboxes

In the United States, the answer is generally no, you cannot put unstamped mail in mailboxes. Here's why:

  1. Postal regulations: The United States Postal Service (USPS) requires that all mail pieces be properly stamped with the correct postage before being deposited in a mailbox or at a post office.
  2. Mailbox rules: Mailboxes are intended for use by residents and businesses to deposit mail that has been properly prepared and paid for. Unstamped mail is not considered "properly prepared" and may not be accepted by the USPS.
  3. Postage due: If an unstamped piece of mail is deposited in a mailbox, it may be returned to the sender with a "postage due" notice, which requires the sender to pay the applicable postage rate.

However, there are some exceptions and alternatives:

  1. Postage-paid envelopes: If you have a postage-paid envelope (e.g., a bill or catalog), you can deposit it in a mailbox without additional postage.
  2. Post office drop-off: You can take unstamped mail to a post office and pay for the postage there. The postal clerk can help you determine the correct postage rate and apply it to your mail piece.
  3. Online postage: Some online services, like Stamps.com or Endicia, allow you to purchase and print postage labels for your mail pieces. You can then deposit the mail in a mailbox or at a post office.

In summary, while you can't put unstamped mail in mailboxes, there are alternative ways to send your mail, such as using postage-paid envelopes, visiting a post office, or using online postage services.
