About This Publisher Prefix
Random House is one of the world's largest and most prestigious book publishers, part of Penguin Random House.
The publication number segment following the publisher prefix is 5 digits long, giving this publisher a theoretical capacity of up to 100,000 unique ISBNs within this prefix.
The ISBN system works by dividing the 9-digit body of an ISBN (after the EAN prefix) into three parts: registration group, registrant (publisher), and publication number. Shorter publisher prefixes indicate larger publishers who need more publication numbers; longer prefixes are assigned to smaller presses with fewer titles.
