If a survey is performed by a firm rather than an individual, what number must appear on the drawing besides the surveyor's license?

When a survey is conducted by a firm rather than an individual, it is important for transparency and regulatory compliance that the Certificate of Authorization number be included on the drawing alongside the surveyor’s license. The Certificate of Authorization is a designation granted to firms that authorizes them to perform professional services, ensuring that the firm meets the necessary legal and regulatory standards for practice in the field of surveying.

Including this number not only signifies that the firm is legally recognized for providing such services, but it also helps to ensure accountability and quality assurance in the work being performed. It allows regulators, clients, and other stakeholders to verify that the firm is operating under valid authority, thus reinforcing trust in the surveying process.

Other numbers like the License Registration number or the firm’s identification number may have significance in other contexts but do not specifically indicate the authorization of the firm to provide professional surveying services. Similarly, the Tax Identification number is related to taxation and financial matters, which is not relevant to the certification of surveying practice.
