What plan number format was introduced in 1973 for land registration?

The format of seven digits with additional identifiers was introduced in 1973 for land registration to provide a more organized and systematic way to catalogue land titles. This format allows for a unique identification of each land parcel, accommodating a growing population and the consequent increase in land transactions. The use of seven digits ensures a large enough number range to uniquely identify numerous land properties, while additional identifiers can denote specific attributes or categorize the land in various ways, enhancing the management and tracking of land records.

This format aligns with the need for efficiency and clarity in land registration processes, making it easier for landowners, authorities, and searchers to access and verify land ownership information. It reflects a broader trend towards modernization in the handling of land registration, moving away from previous, simpler systems that may have been prone to errors or complications as the number of land transactions grew.
