Quick take: A “No Mapping” SIR notice is not the same thing as a deletion order. It means the election authorities could not establish the required link between your current electoral-roll record and the earlier roll used for the SIR exercise. The next step is verification: read the notice, attend the hearing, carry the right documents, and get proof that you appeared.
The biggest mistake is treating the notice like a WhatsApp rumour—or ignoring it because your name is still visible online.
If the notice has your name, treat the date on it seriously.
This guide is specifically about the SIR hearing and document verification. It is not a guide to Forms 6/7/8, the DEO/CEO appeal process after an adverse order, finding your BLO, or a complete ECINET tutorial.
First: what does “No Mapping” mean?
During Karnataka's 2026 SIR, election authorities compared current electoral-roll information with the previous SIR data, including the 2002 electoral roll. Karnataka's official district election pages are also publishing the 2002 rolls alongside the current SIR material. (Chitradurga District)
If the system cannot establish that link, an elector can be placed in the “No Mapping” category.
That does not automatically mean you are not a voter.
It means the election machinery needs you to provide information or documents so the discrepancy can be examined.
There is another category called “Anomalies”, where a link may exist but the information contains a logical discrepancy—for example, an unusual age or relationship combination.
Don't assume the two notices require exactly the same paperwork.
Read the reason printed on your notice.
Why this matters in Karnataka right nowThis isn't a theoretical exercise.
Karnataka has generated more than 43 lakh notices in the “No Mapping” and “Anomalies” categories during the current SIR. In Bengaluru alone, more than 24 lakh notices were generated, including about 17.81 lakh No Mapping cases and 6.24 lakh anomaly cases. (The New Indian Express)
Hearings are being handled by EROs/AEROs, with additional officers brought in to deal with the volume. Officials have specifically asked voters to attend at the date and time mentioned in their notices. (The New Indian Express)
So don't look at the number and think:
“There are millions of notices. They won't care about mine.”
Your file still has your EPIC, your part, your serial number and your hearing date.
Take care of your file.
Step 1: Read the notice like a document, not a warningBefore collecting anything, check the notice carefully.
Look for:
- Your full name
- EPIC number
- Part number
- Serial number
- Reason for the notice
- Hearing date
- Hearing time
- Hearing venue
- Name/designation of the officer, where mentioned
- Any document list or instructions
- QR code or digital submission instructions, if provided
Take a clear photograph of the entire notice.
Then save it somewhere other than WhatsApp.
Create a folder:
SIR 2026 → Your Name → Notice
Put every document related to the case inside it.
This sounds excessive.
It isn't.
When a file becomes complicated three weeks later, you will be glad you did it.
Step 2: Check your current voter recordBefore the hearing, search your name on the official ECI voter services system.
The ECI currently provides facilities to search the electoral roll, track applications and access SIR-related services. Its SIR portal also provides a facility to search your name in the last SIR electoral roll. (Voter Information)
For Karnataka, also check the relevant 2002 electoral roll through the official election authorities.
Don't search only for an exact spelling.
Old electoral rolls can contain differences in:
- initials
- spelling
- surname order
- transliteration
- relationship names
- age
The ECI's SIR search itself warns that spellings can vary between the last SIR details and current records and recommends trying variations where necessary. (Voter Information)
Your objective
Try to establish:
Who was I in the old roll?
and
Who am I in the current roll?
If you can connect those two records, your hearing becomes much easier to explain.
Step 3: Build your document fileDon't arrive with one Aadhaar photocopy and say:
“Sir, I have been voting here for years.”
Your personal history may be completely genuine.
But the officer still needs something that can be examined and recorded.
Build three small piles.
Pile 1 — Your current identity
Carry:
- Original EPIC
- Photocopy of EPIC
- Aadhaar, if you have it
- Another government-issued identity document where relevant
Importantly, the Election Commission has specifically directed that Aadhaar can be accepted as a proof of identity, but it is not proof of citizenship in this SIR context. (Election Commission of India)
So don't walk into the hearing believing:
“I have Aadhaar, therefore the matter is automatically finished.”
It isn't.
Pile 2 — Evidence that connects you to the rollThis is where preparation matters.
Depending on your circumstances, useful records can include:
- Your old voter details
- A parent's old EPIC/roll entry where it genuinely establishes the relationship
- Birth certificate
- School or SSLC/matriculation records
- Passport
- Other government records showing relevant identity or family details
- Documents referred to in the notice or applicable SIR instructions
Don't collect documents just because somebody posted a giant list on Facebook.
Start with the notice and the official instructions for your state.
The exact evidentiary requirement can depend on the category and the instructions applicable to the SIR.
Pile 3 — Your current residence and timelineIf your situation involves moving from one place to another, make that story easy to understand.
For example:
2002: Family lived in Mysuru
2010: Moved to Bengaluru
2012: Current EPIC issued
2018: Moved from Indiranagar to present address
2026: Current electoral-roll entry
Then attach documents that support the relevant parts of that timeline.
Possible supporting records can include:
- Electricity/water bills
- Rent agreement
- Property or society records
- Other official address documents
The goal isn't to produce a suitcase full of paper.
The goal is to make the officer's job easier:
“This is who I am. This is where I was. This is how the old record connects to me.”
Aadhaar is useful—but don't make it your entire fileThis deserves its own section because there is a lot of confusion around it.
The ECI's September 2025 instructions, issued following the Supreme Court's direction, added Aadhaar as an additional document for the SIR process and stated that it is to be used as proof of identity, not proof of citizenship. (Election Commission of India)
So:
Carry Aadhaar.
But also carry the other documents that actually help establish the facts relevant to your notice.
A strong file is better than:
“I brought Aadhaar. What else do you want?”Step 4: Make two photocopy sets
This is one of those boring pieces of advice that saves trouble later.
Take:
Originals + 2 photocopy sets.
Keep the originals with you.
Hand over copies unless the officer specifically needs to inspect an original.
If an original has to be retained for any reason, ask what receipt or acknowledgement will be provided.
Don't casually leave your only original certificate on a desk.
Step 5: Write a one-page explanationDon't make the officer reconstruct your story from twelve documents.
Write one page.
Example
Subject: Explanation regarding No Mapping SIR Notice
I am [name], EPIC [number], residing at [address].
My current electoral-roll entry is in Part [number], Serial [number].
I have been ordinarily residing at [place] since [year].
My relevant previous electoral-roll / family record is [brief explanation].
The difference between the old and current record is [name spelling / address / migration / other reason].
I am enclosing copies of the following documents:
- EPIC
- Aadhaar
- [Document]
- [Document]
- [Old roll/parent record]
I request that my documents and explanation be taken on record and my electoral-roll entry be considered accordingly.
Name:
EPIC:
Mobile:
Date:
Keep the language boring.
Boring is good.
You're building a file, not writing a speech.
What happens inside the hearing?Don't expect a courtroom drama.
The purpose is verification.
Officials have said hearings involve document checking and recording the elector's appearance and supporting information. Karnataka officials have also said photographs and documentation are being recorded through the BLO/election system, with voters signing the relevant attendance/documentation register. (The New Indian Express)
Depending on the case, you may be asked questions such as:
- Where were you residing during the relevant period?
- What was your name in the earlier record?
- Who were your parents/relatives?
- When did you move?
- Which document establishes the connection?
- Why is the spelling different?
Answer directly.
If you don't know something, say:
“I don't know that detail, but I have this document.”
Don't guess.
Three things to ask before leavingYour hearing may take only a few minutes.
Use those minutes properly.
1. “Has my appearance been recorded?”
Make sure you haven't simply handed papers to someone and walked away.
2. “Are any additional documents required?”
If yes, ask them to tell you exactly what is missing.
Write it down.
3. “How will I know the outcome?”
Ask whether you will receive an order, whether anything further is required, and how the next communication will reach you.
If an acknowledgement or reference is available, keep it.
Don't sign a blank sheetThis should go without saying, but say it anyway.
Read anything before signing.
If you don't understand a document, ask what it records.
Don't sign a blank page.
Don't hand over originals without understanding why they are being retained.
And don't let somebody tell you:
“Sign here. Everyone signs it.”
Your signature is yours.
What if you cannot attend?This is especially important for:
- senior citizens
- bedridden voters
- injured voters
- persons with disabilities
- people with serious mobility problems
Karnataka election officials have publicly said that people who cannot attend in person should contact officials/BLOs and that suitable arrangements can be made, including deputing a family member or having officials visit the home in appropriate cases. (The New Indian Express)
Do this before the hearing date if possible.
Don't simply miss the appointment and explain later.
Call the number on the notice, contact the BLO/election office, and document the request.
Keep screenshots of messages and notes of whom you spoke to.
What if you never received the notice?Don't assume:
“No paper means no problem.”
Check.
The ECI provides electoral-roll and SIR search facilities online, while state and district election offices are publishing SIR-related material. (Voter Information)
If you believe your name has been flagged but the physical notice never reached you:
- Check the official SIR/electoral-roll information.
- Contact the BLO or election office.
- Ask for the hearing details.
- Keep a record of your request.
Don't wait until the final roll appears.
What happens if you miss the hearing?This is where you should be particularly careful.
Don't assume that missing one appointment automatically deletes your name.
But don't assume the opposite either.
Contact the election authorities immediately and ask whether another opportunity/date is available.
Karnataka officials have said arrangements can be made for voters who genuinely cannot attend, but you should communicate with the authorities rather than simply disappear from the process. (The New Indian Express)
If you ultimately receive an adverse order, that becomes a different stage of the process.
That's when you move from “prepare for the hearing” to “challenge the order.”
Don't mix those two stages.

Print this the night before.
Then stop worrying and go.
The biggest mistakes to avoid“My name is still online, so I don't need to attend.”
Wrong approach.
A notice means the authorities are asking for verification. Deal with the notice.
“Aadhaar will solve everything.”
No.
Aadhaar is accepted as identity proof in the applicable SIR process, but it is not citizenship proof. (Election Commission of India)
“The BLO said I'm fine, so I don't need to go.”
If you have a formal hearing notice, follow the notice.
A verbal assurance is not the same thing as your file being disposed of.
“I'll upload the documents and skip the hearing.”
Don't assume digital submission replaces an appearance unless the authorities specifically tell you it does.
“I'll take the originals and leave them there.”
Don't.
Carry them for verification. Keep copies for the file.
After the hearing: don't forget about yourselfThe hearing isn't the end of your job.
Keep your notice, documents and acknowledgement together.
Then check the official electoral-roll status as the SIR process moves forward. The ECI provides online electoral-roll search and application/status facilities. (Election Commission of India)
If an adverse speaking order is eventually passed, that is a different stage and you may need to look at the applicable appeal/remedy process.
Don't start that paperwork prematurely.
First:
Show up.
Submit the evidence.
Get the record of your appearance.
Track the outcome.
One final rule: don't let WhatsApp run your voter fileDuring SIR, you'll hear everything:
“Everyone has been deleted.”
“Aadhaar is compulsory.”
“Just give this document.”
“Don't attend the hearing.”
“The BLO can fix it.”
“The list has already been finalised.”
Stop.
Open the notice.
Check the official ECI/CEO information.
Ask the election office.
Then act.
The ECI's official voter services currently provide direct access to electoral-roll search, SIR services, application tracking and information about ERO/BLO contacts. (Voter Information)
Your vote is too important to manage through a forwarded screenshot.
Where NetaSampark fits
This is an election-roll verification process, so the ERO/election machinery remains the authority handling your individual file.
An elected representative cannot substitute for that process.
But if an entire neighbourhood is facing the same problem—missing notices, inaccessible hearing venues, repeated documentation failures, or systemic communication problems—document the pattern and raise it through the appropriate civic channels.
You can find your elected representatives on NetaSampark and keep the political follow-up separate from the statutory election process.
Be informed. Be heard.
A No Mapping notice is not a reason to panic.
It is a reason to prepare.
Read the notice. Find the old record. Build the file. Attend the hearing. Get the acknowledgement.
Don't leave your voter record to chance.
Non-partisan civic explainer. SIR procedures, hearing arrangements and document requirements can vary by state and by the instructions applicable to the current revision. This article uses Karnataka's 2026 SIR as the practical example. Always follow the notice issued to you and verify the latest instructions through the Election Commission of India or the relevant Chief Electoral Officer.
