What is a characteristic of permit imprint postage?

Permit imprint postage is a method commonly employed by businesses for bulk mailing. This option is specifically designed to streamline the mailing process for large quantities of mail, allowing businesses to use a pre-printed indicia instead of individual postage stamps. This indicia clearly indicates that the postage has been paid via a permit, which simplifies the mailing process by avoiding the need for affixing multiple stamps.

The bulk mailing feature makes this type of postage particularly advantageous for businesses that send out mass mailings, such as marketing materials, newsletters, or invoices, thereby reducing their mailing costs and administrative efforts. In contrast, the other options do not accurately represent the features of permit imprint postage. For instance, it is not limited to international shipping nor restricted to personal mail, and it does not involve purchasing single stamps. These characteristics highlight the specialized nature of permit imprint postage tailored to business mailing needs.
