About 21 billion UL Marks appear on products each year. Underwriters Laboratories® strives for certification programs that are convenient for manufacturers, trustworthy and reputable. To ensure the integrity of the UL Mark, UL has developed a holographic Mark that is very difficult to copy without authorization. To make the UL Mark more convenient for manufacturers who private label some of their products, UL provides a multiple listing service. And to make the data acceptance program convenient for manufacturers without lowering the high bar of reliability, UL has strict regulations on how its data acceptance policy is run.

The redesigned label incorporates cutting-edge technology, elevated security features and a unique hologram design, making it easy to identify and validate, yet incredibly difficult to replicate.
