Which element uniquely identifies the survey plan?

• A. Landowner Name
• B. Unique Survey Reference Number
• C. Date of Survey
• D. Central Point Coordinates

Answer: (B)

What makes a survey plan uniquely identifiable is its Unique Survey Reference Number. This number is an official, one-and-only tag assigned to each plan within the cadastral system, linking precisely to that specific document and its metadata in the land administration records. Because it is unique, it remains the definitive reference for retrieval, verification, and cross-checking, regardless of who the landowner is, when the survey was done, or where the central point is located. In contrast, a landowner’s name can appear on many plans, the date of survey can repeat across different plans, and central point coordinates describe a location rather than a unique document. Thus, the unique survey reference number is the sole element that guarantees a plan is identified without ambiguity.
