Do you need to compress Aadhaar or passbook PDFs for e-Shram?

You do not need to upload an Aadhaar PDF or a bank passbook PDF to register on e-Shram: the official e-Shram FAQ lists only your Aadhaar number and an Aadhaar-linked mobile number, and your bank details are typed into the form, not uploaded as a scan.

Many guides tell e-Shram applicants to shrink their Aadhaar and passbook scans to a "100 KB to 500 KB" range before registering. The Ministry of Labour and Employment's own FAQ does not mention any upload or any file size rule, so that advice sends workers looking for a problem they will not meet. This guide explains what e-Shram registration actually needs, where a compressed PDF can still be useful, and how to make one when another portal asks for it.

Key takeaways

• e-Shram registration needs your Aadhaar number and the mobile number linked to it; there is no document upload in the official FAQ.
• If your mobile is not linked to Aadhaar, you can register at a Common Service Centre (CSC) or State Seva Kendra with fingerprint authentication, and the FAQ says no documents are submitted there.
• Registration is free, and the e-Shram card (UAN card) does not expire.
• You may still need a compressed Aadhaar or passbook PDF for other schemes, bank KYC or state portals; always follow the limit shown on that portal's upload screen.

What e-Shram registration actually asks for

e-Shram is the national database of unorganised workers run by the Ministry of Labour and Employment. Each registered worker gets a 12-digit Universal Account Number (UAN). According to the e-Shram FAQ, a worker needs two things to register: an Aadhaar number and an Aadhaar-linked mobile number.

The same FAQ answers three questions that matter for anyone preparing paperwork:

• Proof of date of birth or income: "At present there is no requirement to provide any proof of date of birth and income."
• Documents at a CSC: a worker who registers at a Common Service Centre does not submit any documents; the Aadhaar number and a mobile phone are enough.
• Photo: the photo on your e-Shram record comes from Aadhaar, so you do not upload one. If you update the photo in Aadhaar, it appears on e-Shram after Aadhaar re-eKYC on the portal.

Your bank account number and IFSC are entered as details in the form. A 2021 notice from the Nagaland Department of Information and Public Relations lists them, alongside Aadhaar and mobile number, among the details needed, and neither that notice nor the e-Shram FAQ mentions uploading a passbook scan. The FAQ also says you can update bank account information after registration by logging in with your UAN and an OTP.

Who can register on e-Shram

The e-Shram FAQ defines an unorganised worker as someone engaged in unorganised work who is not a member of ESIC or EPFO, and says any such individual aged 16 or above is eligible. It states that there are no income criteria and that agricultural labourers and landless farmers can register.

Older material can differ. The 2021 Nagaland notice, for example, gives an age band of 16 to 59 and excludes income tax payers. When an older notice and the current FAQ disagree, rely on the current e-Shram FAQ and confirm with the helpline.

How to register without uploading anything

1. Open eshram.gov.in and choose the self-registration option.
2. Verify your Aadhaar-linked mobile number and your Aadhaar number with the OTPs the portal sends.
3. Fill in the form fields for personal, address, education, occupation and bank details.
4. Submit the form, then log in with your UAN to use the Download UAN Card option.

If your mobile number is not linked to Aadhaar, go to a CSC or State Seva Kendra instead; the FAQ says they can register you with biometric authentication.

When you might still need a compressed Aadhaar or passbook PDF

e-Shram itself does not ask for scans, but the same documents are requested elsewhere: some state welfare schemes, bank and post office KYC forms, and scholarship or pension portals. Those portals often set a per-file size cap, and the cap differs between portals. The right number to use is the one printed on the upload screen or in the scheme's official notice, not a figure copied from a blog.

Several state scheme guides on this site cover portals that do ask for uploads, such as Lakshmir Bhandar in West Bengal and Udyam registration documents.

How to compress an Aadhaar or passbook PDF when a portal asks

1. Unlock e-Aadhaar first if needed. The e-Aadhaar PDF downloaded from UIDAI is password protected. Adobe's guide explains that the password is the first four letters of your name in capital letters followed by your year of birth (for example RANI1984). Remove the password with Unlock PDF using that password, because many portals reject protected files.
2. Combine pages if the portal wants one file. Put the front and back of a card, or the passbook's first page and a cancelled cheque, into one PDF with Merge PDF.
3. Compress to the portal's limit. Open the e-Shram card PDF compressor or the general Compress PDF tool, pick a target size that sits safely under the limit shown on the upload screen, and download the result.
4. Check readability. Zoom in on the Aadhaar number, account number and IFSC. If they are blurred, run the original again with a larger target size.

Compress PDF runs on Siliph's servers: the upload is encrypted, processing is automatic and files are deleted within 2 hours. If you would rather not upload an identity document to any third-party site, ask the scheme office whether it accepts an assisted application or a photocopy instead.

Frequently asked questions

Do I need to upload my Aadhaar card PDF to register on e-Shram?

No. The official e-Shram FAQ lists only the Aadhaar number and an Aadhaar-linked mobile number as requirements, and Aadhaar is verified online through OTP or, at a CSC, through fingerprint authentication.

Do I need to upload my bank passbook for e-Shram?

The official pages reviewed for this guide do not mention a passbook upload. You enter your bank account number and IFSC in the form, and you can update bank details later by logging in with your UAN and OTP.

What is the file size limit for e-Shram documents?

The e-Shram FAQ does not state any file size limit because it does not describe a document upload. Figures such as "100 KB to 500 KB" that circulate online are not from the official FAQ.

Is e-Shram registration free?

Yes. The FAQ says registration on the e-Shram portal is totally free and workers do not pay any registering entity. Report anyone who asks for money to the helpline on 14434.

Can I register on e-Shram if my mobile number is not linked to Aadhaar?

Yes. Visit a Common Service Centre or State Seva Kendra, where you can register using biometric authentication; the FAQ says you only need your Aadhaar number and mobile phone.
