Suresh Jadhav had already filled the MAHABOCW registration form twice. Both times, same result — rejected. His Aadhaar was fine. Bank details were correct. The problem was one document: the 90-day work certificate (90 दिवस कामगार प्रमाणपत्र). Wrong format. No contractor stamp. Incomplete dates.

Third time, he downloaded the correct format from mahabocw.in, got it signed by his Gramsevak, and submitted it. Approved in 11 days.
The Bandhkam Kamgar Yojana 90-day work certificate is the single most common reason registrations get rejected at MAHABOCW. This guide covers exactly what the certificate must contain, who can sign it, how to fill it, and what to do if your contractor refuses.
💡 Quick Answer: The 90-day work certificate (90 दिवस कामगार प्रमाणपत्र) proves you worked in construction for 90+ days in the last 12 months. Rural workers get it from the Gramsevak (ग्रामसेवक). Urban workers get it from their contractor or developer. Download the official 2026 format at: 👉 mahabocw.in/en/download/
What Is the 90-Day Work Certificate?
MAHABOCW registration requires proof that you have worked as a construction worker (बांधकाम कामगार) for at least 90 days in the last 12 months. This proof is the 90-day work certificate — officially called the Work Experience Certificate under Form-V of the BOCW Act.
Without this certificate, your registration form cannot be submitted. Without registration, you cannot claim any of the 20+ benefits under Bandhkam Kamgar Yojana — no ₹5,000 payment, no marriage grant, no scholarship, no insurance.
It is not a certificate you generate yourself. It must be signed by an authorized person — either a Gramsevak, contractor, or developer — who confirms your employment.
Why so many rejections happen: Workers either use an old format, miss mandatory fields like site address or work period dates, or submit without an official stamp. The portal auto-rejects these without explanation. This guide helps you avoid all of those.
Who Can Issue the Certificate?
Two different routes depending on where you live and work:
| Worker Type | Issued By | Where to Go |
|---|---|---|
| Rural (village/gram panchayat area) | Gramsevak (ग्रामसेवक) | Gram Panchayat office |
| Urban (city / municipal area) | Contractor or Developer | Site office or contractor directly |
| Either area (if contractor refuses) | Use Form-E | MAHABOCW district office |
All three are valid. MAHABOCW accepts certificates from any of these sources — as long as the format is correct and the stamp is present.
Download the Official 2026 Format
The official certificate format is available on the MAHABOCW download page. Do not use formats downloaded from other websites — the portal scans for the correct structure and rejects unofficial versions.

How to Fill the Certificate — Field by Field
Both formats (Gramsevak and Contractor) require the same core information. Here is what each field means and what to write:
Worker Details Section:
- Full Name — Exactly as on Aadhaar card. No nicknames, no short forms.
- Father’s / Husband’s Name — As on Aadhaar.
- Date of Birth — DD/MM/YYYY format.
- Address — Permanent address as on Aadhaar. Include village/ward, taluka, district, PIN.
- Aadhaar Number — 12-digit number. Write clearly.
Work Details Section — This is where most mistakes happen:
- Nature of Work — Be specific: “Mason” / “Carpenter” / “Plumber” / “Helper” / “Painter” / “Electrician” / “Tile Worker”. Do not write just “Labour” or “Worker” — this causes rejections.
- Construction Site Address — Full address of the site where you worked. Road name, area, city, PIN. This must be verifiable.
- Period of Work (From – To) — The exact start and end dates of your 90-day work period. Example: “01/04/2025 to 30/06/2025.” Both dates mandatory.
- Total Days Worked — Must be 90 or more. Write the actual number — “92 days” or “95 days.”
- Type of Construction Work — Building / Road / Bridge / Infrastructure. Match what you actually worked on.
Certifier Details Section:
- Name of Gramsevak / Contractor / Developer — Full name.
- Designation — “Gramsevak, [Village Name] Gram Panchayat” or “Contractor” or “Site Engineer.”
- Official Stamp — Mandatory. Round seal of Gram Panchayat (for Gramsevak) or contractor’s firm stamp. No stamp = automatic rejection.
- Signature — Signed in ink. Digital signatures not accepted for physical form.
- Date of Issue — Date when the certificate is being signed. Must be recent — not older than 3 months from your registration date.
Getting It from Gramsevak — Rural Workers
The Gramsevak (ग्रामसेवक) is the government-appointed secretary of your Gram Panchayat. For rural construction workers, the Gramsevak is the official authority to certify your 90-day work.
What to bring to the Gram Panchayat office:
- Aadhaar card (original + photocopy)
- Printed 90-day certificate form (downloaded from mahabocw.in)
- Any one supporting document: wage slip, site ID card, or a letter from your contractor confirming you worked there
Step-by-step process:
Step 1 — Download the Gramsevak format from mahabocw.in/en/download/
Step 2 — Fill in all worker details and work details yourself (in pen, clearly)
Step 3 — Visit your Gram Panchayat office with Aadhaar and the filled form
Step 4 — Meet the Gramsevak and explain you need the certificate for MAHABOCW registration
Step 5 — The Gramsevak verifies your details, signs the form, and stamps it with the official Gram Panchayat seal
Step 6 — Collect the signed, stamped certificate
Step 7 — Scan it clearly and upload on mahabocw.in
“Most Gramsevaks are familiar with this certificate now,” said a worker from Satara. “I went at 10am, showed my Aadhaar, and had the certificate by 11:30. No fee, nothing.”
Important: The Gramsevak cannot charge any fee for this certificate. It is a free government service. If asked for money, report to the district collector’s office.
Getting It from Contractor — Urban Workers
For workers in cities and towns, the certificate must come from the contractor, developer, or site engineer you worked under.
What to ask your contractor:
- Download the contractor format from mahabocw.in
- Fill in the worker details section yourself
- Request the contractor to verify and fill the work details section
- Ask for official firm stamp + signature
What must be on the contractor certificate:
- Contractor’s firm name and address
- Site address where you worked (specific building/project name)
- Your exact work period (from–to dates)
- Your role / nature of work
- Contractor’s official rubber stamp (firm stamp, not personal)
- Contractor’s signature with date
“Many contractors are now used to this,” said a plumber from Pune who registered in February 2026. “I just WhatsApped the blank form to my contractor, he filled his part, signed it, and sent it back. I got it stamped at his office the next day.”
If your contractor has multiple workers registering: Ask the contractor to sign all forms together — they often prefer batch processing over individual visits.
What If Contractor Refuses? — Form-E
Many contractors avoid signing certificates fearing labour law scrutiny. If your contractor refuses, you have a legal alternative: Form-E.
Form-E is an Employer Declaration form under the BOCW Act. It serves the same purpose as the 90-day certificate — and it is available at the MAHABOCW district office.
How to use Form-E:
Step 1 — Visit your nearest MAHABOCW district office (find locations at mahabocw.in)
Step 2 — Ask for Form-E (Employer Declaration for Worker Registration)
Step 3 — Fill in your details and the contractor’s details
Step 4 — Take the form to your contractor and request a signature. If the contractor still refuses, bring two witnesses from the same site who can sign as witnesses to your employment.
Step 5 — Submit Form-E at the MAHABOCW office. They will process it.
If contractor is untraceable: Go to the MAHABOCW district office directly and explain the situation. Officers can accept a sworn affidavit (notarized) in exceptional cases.
RTI tip: Mentioning “Right to Information Act” when dealing with an uncooperative contractor or Gramsevak often speeds things up considerably. Asking for their official refusal in writing rarely gets refused — they usually just sign.
Common Rejection Reasons + Fixes
These are the exact reasons MAHABOCW rejects 90-day certificates:
Rejection 1: “Wrong format” Fix: Only use the format from mahabocw.in/en/download/. Formats from other websites are rejected.
Rejection 2: “Stamp missing” Fix: Gram Panchayat seal or contractor firm stamp is mandatory. No personal stamps — must be an official round seal or rubber stamp.
Rejection 3: “Work period not specified” Fix: Write exact from–to dates. “April to June 2025” is not enough — write “01/04/2025 to 30/06/2025.”
Rejection 4: “Nature of work too vague” Fix: Write your specific trade — “Mason” / “Carpenter” / “Electrician.” Not just “Labour” or “Construction Worker.”
Rejection 5: “Site address incomplete” Fix: Full site address with road, area, city, PIN required. “Near station” is not a valid address.
Rejection 6: “Certificate older than 3 months” Fix: The certificate date must be within 3 months of your registration submission date. If your certificate is old, get a fresh one signed.
Rejection 7: “Scan is blurry / unreadable” Fix: Scan in at least 300 DPI. Mobile camera photos are accepted only if sharp and well-lit — all text must be readable. File under 1MB.
Rejection 8: “Name mismatch with Aadhaar” Fix: Worker’s name on the certificate must match Aadhaar exactly — spelling, middle name, everything.
