What must be present around each Ancillary Service Endorsement?

The correct answer emphasizes the requirement for a ¼ inch clear space around each Ancillary Service Endorsement. This clear space is crucial to ensure that the endorsement is easily readable and distinguishes it from other printed materials on the mailpiece. Maintaining this specified clear space helps postal services efficiently process and accurately deliver mail. Adequate spacing prevents any misinterpretation or visual clutter that could arise from other design elements or text overlapping the endorsement. This precision in formatting is especially important for endorsements, as it aids in compliance with postal standards, ensuring the mailpiece is recognized and handled correctly without delays or issues.
