Request Form Pricing & Delivery Schedule are below, under the Fees section. 

Label Verification Letter

IBTS provides a verification letter by fax or email to verify the following information on manufactured homes:

  • Label Number
  • Serial Number
  • Date of Manufacture
  • Name of the Manufacturer and Plant Location
  • Location of First Destination (usually the retailer)

Please note that this letter does NOT contain wind zone, roof load or thermal information.

IBTS maintains data regarding the required certification labels and data plates for manufactured homes. Please note that certification labels are not replaced. The verification letter provided suffices in most cases for missing certification labels or unknown manufacturer data for specific homes.

Note: Details for manufactured homes built before June 15, 1976 are not available. If you know the home was built before this date, or it is a modular home, please do not submit a request, as we do not have this information and therefore cannot research these homes.


IBTS CANNOT ACCEPT SECURE OR ENCRYPTED EMAIL MESSAGES. If you are submitting a request via email using the downloadable .PDF form below, you will have to send it as a STANDARD EMAIL ATTACHMENT. Please allow a full business day for the request information to be processed into our system.
For status updates on your request, cancellations or discrepancy claims, please email the Labels Department at
