Which of the following is NOT true regarding mail piece acceptance?

The assertion that all items must be weighed is not accurate when discussing mail piece acceptance. While weighing certain types of mail may be required to determine the correct postage, it is not a blanket requirement for all mail pieces. There are various postal products and services that allow for non-weighted acceptance, especially for standardized mail like letters that fit specific criteria.

Factors such as the mail piece's size, shape, and weight class play a role in determining if it can be mailed, but not every item must be weighed before acceptance, especially if it already meets the necessary requirements for postage based on its classification or if it falls into a category where standardized rates apply. Thus, the understanding of mail acceptance highlights that while ensuring proper postage is crucial, the requirement to weigh every item does not apply universally.
