The HUD data plate (HUD calls it a performance certificate) is usually located on the wall of the master bedroom closet or inside of a cabinet door in the kitchen. But if you can’t find it and need a duplicate for insurance, financing, or sale of the home, you can get one from IBTS (Institute for Building Technology and Safety). You must provide them with the HUD tag number or serial/VIN number for the home.

   The HUD tag (also called HUD label or red tag) is located near the bottom of the end of one of the long walls of the home. A double or triple-wide will have multiple tags. The serial/VIN number is etched into the front face of the front cross-beam of the steel undercarriage.

   Their fee, as of December, 2017, is $100 for email delivery of a duplicate data plate. If they cannot provide a data plate, they will send a performance certificate. It takes two weeks for processing, and there are extra fees for rush service (2 to 3 days) and delivery of a paper copy of the form. You can apply online at https://lvr-requests.ibts.org/#/LandingPage. Because they occasionally change the format of their site, this link may not still be valid when you try it, so we suggest going to the home page at and navigating from there if you have a problem.

    The data plate/performance certificate provides the following information about the home: 

•  Serial/VIN number
•  Date of manufacture
•  Name of manufacturer and plant location
•  Wind zone, roof load zone, and thermal zone

    It does not confirm the HUD tag number. You have to order their separate “HUD Label Verification Letter” for an additional fee to receive that information. See our blog post What is a "HUD label verification letter" for a mobile/manufactured home? for more info on label verification letters.

    A couple of final notes: data is only available for mobile/manufactured homes produced after June 15, 1976, which is when HUD took over responsibility of construction standards. Also, IBTS does not keep records for modular homes.
