Hyderabad: In view of the upcoming Special Intensive Revision (SIR) of the voters’ list in Telangana, Booth Level Officers (BLOs) began linking and progeny mapping in Hyderabad.
For the linking or progeny mapping, the voters need to keep their or their relatives’ details from the 2002 SIR voter list.
Recently, Chief Election Commissioner Gyanesh Kumar said the SIR in the states that were not covered in phases I and II will be rolled out soon.
Hyderabad BLOs role in progeny mapping for SIR
In view of the upcoming mammoth exercise in Telangana, BLOs are performing linking or progeny mapping to link or map the names of voters with the 2002 SIR list.
Recently, BLOs were seen visiting houses in the Shaheen Nagar and Sadath Nagar areas.
For those voters whose names are in the 2002 SIR list, linking is done. On the other hand, those who are not in the list will need to link with their relatives whose names are there in the 2002 list.
The Election Commission of India (ECI) allowed mapping with
- Father
- Mother
- Maternal grandfather
- Maternal grandmother
- Paternal grandfather
- Paternal grandmother
However, BLOs are not clear about the rules.
When contacted, a few BLOs in Hyderabad claimed that they are mapping with father, mother, and paternal grandfather only.
ECI’s stand
In the SIR training material used in West Bengal, it is mentioned, “Elector, if not in the last SIR, details of Father, Mother, GF, GM or other relatives on the right side to enter.”
The SIR enumeration form online filling SOP asked electors to select either of the following options:
- My name exists in the Electoral Roll of the last SIR
- My parents’ names (Father, Mother, Grandfather, Grandmother) exist in the electoral roll of the last SIR
- Neither my name nor my parents’ names exist in the electoral roll
These two notifications clearly listed both grandparents, namely the grandfather and grandmother.
It is to be noted that grandparents include both maternal and paternal, and the same was clarified by Uttar Pradesh Chief Electoral Officer (CEO) Navdeep Rinwa.
In multiple interviews, he made it clear that grandparents include both maternal and paternal, which made it clear for BLOs too, and there was no case of denial to link to maternal and paternal grandparents in Uttar Pradesh.
In other states, including West Bengal, details of both maternal and paternal grandparents were allowed to be used for the purpose of mapping during the SIR.
Even in the BLO app, there is an option to link a person in the 2002 list to son, daughter, grandson, granddaughter, or transgender. Here, grandson means “the son of one’s son or daughter” and granddaughter means “the daughter of one’s son or daughter,” thereby clearly allowing linking with both maternal and paternal grandparents.
How to find details from the 2002 list
In order to view details from the 2002 SIR list, the following steps can be followed.
- Visit the Telangana CEO website (click here).
- Click on ‘electoral search’.
- Fill in the details.
- After clicking on ‘search’, details of the previous SIR will appear.
Keep this information ready. It can include information about the voter and his/her relative (father, mother, maternal grandfather, maternal grandmother, paternal grandfather, paternal grandmother).
In view of the upcoming SIR exercise, it is essential that BLOs have clarity about the rules, as progeny mapping will not only reduce the burden of EROs and AEROs, it will also avoid unnecessary notices to voters in Hyderabad and other districts of the state at a later stage.
Documents needed during SIR
If the voter is either linked or mapped successfully, no documents are needed. However, those who remain unlinked and unmapped will receive notice at a later stage of the SIR.
In such cases, the individual needs to submit one of the following 11 documents:
- Any identity card/Pension Payment Order issued to a regular employee/pensioner of any Central Govt./State Govt./PSU.
- Any identity card/certificate/document issued in India by government/local authorities/banks/post office/LIC/PSUs prior to 01.07.1987.
- Birth certificate issued by the competent authority.
- Passport.
- Matriculation/Educational certificate issued by recognised boards/universities.
- Permanent residence certificate issued by a competent state authority.
- Forest Rights Certificate.
- OBC/SC/ST or any caste certificate issued by the competent authority.
- National Register of Citizens (wherever it exists).
- Family register prepared by state/local authorities.
- Any land/house allotment certificate issued by the government.
- For Aadhaar, the Commission’s directions issued via letter No. 23/2025-ERS/Vol.II dated 09.09.2025 shall apply.
- Extract of the Electoral Roll of Bihar SIR with reference to 01.07.2025.
However, the required documents for SIR will be based on the date of birth for all voters in Hyderabad and other Telangana districts. Those who were born before July 1, 1987, need to submit any of the listed documents for themselves.
On the other hand, those who were born on or after July 1, 1987, and on or before December 2, 2004, need to provide a document for themselves and a document of their father or mother.
Those who were born after December 2, 2004, need to submit a document of themselves and both parents.
