Old survey number vs new: how to use the Correlation Statement

Got an old deed with an old survey number that doesn't match your current patta? The Correlation Statement tool links old survey numbers (OS) to new resurvey numbers (RS).

A common headache: your 1970s sale deed lists one survey number, but your current patta shows a completely different one. They can both be correct — the number was changed during a resurvey.

Old (OS) vs Resurvey (RS) numbers

When a village is resurveyed, old survey numbers (OS) are replaced with new resurvey numbers (RS). One old field may be split across several new numbers, or several old ones merged into one.

Use the Correlation Statement

The land-records website has a Correlation Statement tool that maps old survey numbers to the new resurvey numbers for a village. Look up your old number to find the current one that matches it — essential before any registration or dispute.

💡 Once you know your current resurvey number, you can pull the matching FMB sketch and village map and join the sheets here.
