Occasionally we have customers who require vefification of UL (Underwriter Laboratories) certification of Digi products in order to get approval to use our products in their environment.

If you look on any of our product labels where it shows the UL trademark symbol, there will be a number E##### nearby, for example E165880. This number can then be cross-referenced to find the UL certification for the product at the UL Certification Online Resource page.
