Do you have to have last name on mail

In the United States, the United States Postal Service (USPS) does not require a last name on mail, but it is generally recommended to include one for several reasons:

  1. Delivery efficiency: Including a last name helps the USPS deliver mail more efficiently, as it provides a unique identifier for each household.
  2. Reduced errors: Using a last name can reduce the likelihood of mail being misdelivered or lost, as it helps the USPS match the mail to the correct address.
  3. Improved mail sorting: Last names are often used as a primary sorting criterion for mail, so including one can help ensure that your mail is sorted correctly and reaches its intended destination.

That being said, there are some exceptions where a last name may not be required:

  1. Business mail: If you're sending mail to a business, you may not need to include a last name, as the business name is often sufficient.
  2. PO boxes: If you're sending mail to a PO box, you typically don't need to include a last name, as the PO box number is the primary identifier.
  3. Special circumstances: In some cases, the USPS may accept mail without a last name, such as when sending mail to a government agency or a specific department within an organization.

In summary, while a last name is not strictly required on mail, including one can help ensure efficient delivery, reduce errors, and improve mail sorting.
