Q. How much does it cost to obtain a Preassigned Control Number (PCN)?
There is no charge for a Preassigned Control Number (PCN). However, participating publishers are obligated to send a complimentary copy of all books for which a Preassigned Control Number (PCN) was provided immediately upon publication. Publishers failing to meet this obligation may be suspended from the program. Please note that all books submitted to the Library of Congress in compliance with the PCN Program are property of the Library of Congress and therefore are not returnable.
