The Census of India 2011 coding sequence is described as follows, from

DESCRIPTION OF CODING SEQUENCE FOR LOCATION CODE DIRECTORY

As per the recommendations of the MDDS Committee a new coding pattern for various geographical entities has been devised. The Location Code Directory has been provided unique codes on All India basis which can be used for various e-Governance purposes. The coding convention used is as described below:

1. The State code of 2 digits within India has been used similar to the one used in earlier census.
2. The District code of 3 digits continuous code within India has been given.
3. The Sub-district code of 5 digits continuous code within India has been used.
4. The Village code of 6 digits has been used continuous code within India. Range of 000001 – 799999 has been kept for Villages. The Census Towns and OGs which are treated as urban for census purpose have also been included in the Rural Directory. The town code (only statutory towns) have been numbered within India. The town code range is 800001 - 899999.

Further, the provision for new addition, merger or split cases shall be as follows:
Addition Cases:
In case of addition of new Villages/Towns/Sub-DTs/DTs, the new geographical entity shall be added at the end with an incremental code for that geographical entity.
Merger Cases:
In case of merger, the original code of merging geographical units shall be frozen and a new single incremental code shall be given to the merged unit at the end of the corresponding geographical entity.
Split Cases:

In case of split cases the original single code shall be frozen and new individual incremental codes shall be provided at the end of the corresponding geographical entity.

This indicate the coding sequence is comprehensive and addressed for future developments. Following this coding sequence in village boundary geojson files could be useful. The village name filed provided by Census of India is as follows and the Code( STCode-State code, DTCode-District Code, SDTCode- SUb District Code, TVCode- The village code) attribute field can only be retained in geojson.

STCode	DTCode	DTName	SDTCode	SDTName	TVCode	Name
33	000	TAMIL NADU	00000	TAMIL NADU	000000	TAMIL NADU
33	602	Thiruvallur	00000	Thiruvallur	000000	Thiruvallur
33	602	Thiruvallur	00000	Gummidipoondi	000000	Gummidipoondi
