Which documents must display the registration certificate number?

• A. Every bid, proposal, offer, and drawing
• B. Only installation drawings
• C. Only bids
• D. None

Answer: (A)

The key requirement is that the registration certificate number appears on every bid, proposal, offer, and drawing. This ensures that any document related to the project—whether you're submitting a price for work or sharing the design and installation details—can be traced back to a contractor who is officially registered to perform fire sprinkler work. Having the number on all these documents provides immediate verification that the person or company proposing or providing the work is authorized, which helps regulators, plan reviewers, and customers confirm compliance and accountability.

If a document lacks the registration number, it raises a red flag that the work could be reviewed for eligibility or could prompt questions about who is responsible for the installation. The practice of placing the number on all bidding and drawing materials prevents unregistered individuals from presenting themselves as licensed and ensures that the project documentation consistently demonstrates proper authorization.
