The registration number is a critical piece of information that must be included on the tag of a certified boiler. This number serves as a unique identifier for the boiler within official records and allows regulatory agencies to monitor and track the certification status of the equipment. The registration number is essential for ensuring compliance with state regulations, as it confirms that the boiler has undergone the necessary inspections and meets safety standards.

While the other options contain relevant information, they may not be universally required on every certified boiler's tag. For instance, the serial number helps identify individual units, and the inspection date signifies when the last check occurred, both of which are important for operational history but do not serve the same regulatory purpose as the registration number. The owner's address, while useful for contact information, is generally not mandated on the certification tag itself. Thus, the registration number stands out as a key requirement for a certified boiler's tag, emphasizing the importance of adhering to certification protocols and regulatory oversight.
