International Association of Bedding and Furniture Labeling Officials
A uniform registration number system exists for the benefit of manufacturers that sell products in the United States. This allows for only one registration number to be listed on the law label. All states either require or allow a state registration number to be printed on the law label. All states accept or have formally adopted the Uniform Registry Number System.
In order for a Uniform Registry Number to be valid in All STATES, It must be current in the state where it was issued.
Note: As of September 1, 2015, Texas no longer requires a URN.
