Can i mail a 9x12 envelope in a mailbox

In the United States, the standard size for a mailbox is 6.5 inches wide, 1.75 inches deep, and 15 inches tall. The USPS (United States Postal Service) recommends that mailpieces not exceed 11.5 inches in length, 6.125 inches in width, and 1.75 inches in depth to fit comfortably in a standard mailbox.

A 9x12 envelope is slightly larger than the recommended size, so it may not fit comfortably in a standard mailbox. However, it's not impossible to mail a 9x12 envelope in a mailbox, but it may require some extra effort or adjustments.

Here are a few options to consider:

1. Fold the envelope: You can try folding the envelope to make it smaller and more compact, so it can fit in the mailbox. This might require some creative folding, but it's doable.
2. Use a larger mailbox: If you have a larger mailbox or a mailbox with a larger opening, you might be able to fit the 9x12 envelope inside.
3. Use a mail carrier: If you're unable to fit the envelope in your mailbox, you can try placing it in a larger mailbox or asking your mail carrier to collect it from your doorstep.
4. Use a different mailing option: If none of the above options work, you might consider using a different mailing option, such as dropping off the envelope at a post office or using a private courier service.

Remember to always check with your local post office or mail carrier if you're unsure about the size and shape of your mailpiece. They can provide guidance on the best way to mail your envelope.
