How do I know if something is UL approved?

As consumers, we often come across various electrical and electronic products in our day-to-day lives. Whether it's a new kitchen appliance or a phone charger, it's important to ensure that these products are safe to use. One way to determine their safety is by looking for the UL (Underwriters Laboratories) approval mark. In this article, we will explore what the UL approval mark signifies and how you can easily identify whether a product meets UL standards.

Understanding the UL Approval Mark

The UL approval mark indicates that a product has undergone rigorous testing to ensure its compliance with safety standards set by Underwriters Laboratories, a global safety certification company. UL examines the potential risks associated with the product, its construction, and the materials used, to certify that it meets specific safety criteria. This mark assures consumers that the product has met stringent safety standards and is suitable for use. However, simply spotting the UL mark on a product is not enough to guarantee its safety; there are certain elements to consider.

Identifying the UL Approval Mark

When inspecting a product for the UL approval mark, there are a few key aspects to pay attention to. Firstly, look for the distinct UL logo, which consists of a circle within a rounded rectangle. The letters 'UL' will be prominently displayed inside the circle, indicating that the product has received the UL stamp of approval. Secondly, check for additional information accompanying the logo, such as reference numbers or identifiers. These markings help identify the specific UL standard or requirements that the product complies with.

The location of the UL mark can also vary depending on the type of product. For instance, electrical devices usually have the mark on the back or bottom, while power cords may have it imprinted directly on the plug. Keep in mind that some products may display a counterfeit or misleading UL mark, so it's essential to verify the mark's authenticity.

Verifying the UL Approval

To ensure the legitimacy of the UL approval mark, you can take a few additional steps. Start by visiting the official UL website and using their online certification directory. Enter the manufacturer's name or the product's model number to check if it is indeed UL approved. Additionally, be cautious of products that display a "self-declared" UL mark, as these are usually unauthorized claims made by manufacturers who have not undergone proper testing and certification processes.

Beyond verifying the UL mark, don't hesitate to conduct further research on the product itself. Look for customer reviews, safety ratings, and any potential recalls associated with the item. Taking these extra precautions will help you make informed decisions and choose products that prioritize your safety.


Identifying whether a product is UL approved is crucial for ensuring the safety of yourself and your loved ones. By understanding what the UL approval mark signifies, knowing where and how to locate it, and verifying its authenticity, you can confidently purchase electrical and electronic products that meet stringent safety standards. Remember, being an informed consumer allows you to make choices that prioritize your well-being.
