CableOrganizer has released guidelines of how you can see the different between a fake and real UL mark. Four major elements are key to see if the UL mark is real.

- UL letters need to bee diagonally (appearing from left to right) in a circle together with a small ® symbol under the letter “U”

- Word “listed” needs to be in capital, below or beside the circle

- A control number needs to be displayed, either a 4-character alphanumeric control number, or a 4 to 6-digit issue number.

- Needs to have a product identity phrase (name of what the product is)
