Is media mail the same as book rate

In the United States, Media Mail and Book Rate are often used interchangeably, but they are not exactly the same thing.

Media Mail is a type of mail service offered by the United States Postal Service (USPS) that allows for the mailing of certain types of media, such as books, CDs, DVDs, and vinyl records, at a lower rate than regular First-Class Mail. Media Mail is only available for mailpieces that weigh 13 ounces or less and are sent to addresses within the United States. The rates for Media Mail are generally lower than those for First-Class Mail, but the delivery time is typically longer, taking 2-8 business days.

Book Rate, on the other hand, is a specific type of Media Mail that is used exclusively for mailing books. Book Rate is a discounted rate for mailing books that weigh 1 pound or less and are sent to addresses within the United States. Book Rate is only available for books that are printed and bound, and not for other types of media, such as CDs or DVDs.

In summary:

So, while all Book Rate mail is Media Mail, not all Media Mail is Book Rate.
