Twin Cities Industries (TCI) is a manufacturer of the highest quality and most durable reflective numbers and letters used by utility companies and municipalities for marking above and below ground electrical, telephone, fiber optic and gas transmission lines. In addition, TCI makes custom labels, utility tags, pipe markers and other utility marking systems.

In addition to being highly visible and reflective, all of our numbers and letters are laminated with a clear protective film which gives them even greater durability and protection from weather and sunlight. They also have a wide tab on the side so they are easy to peel and apply even in adverse conditions or while wearing gloves.

Our standard sizes come in packs of 100 but we produce custom orders to fit our customer's needs.
