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 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.
