Sarkari Naukri Bio-Data Format — Complete Hindi Guide (सरकारी बायोडाटा)

Bio-data includes personal details a resume does not

Father's name, mother's name, caste category, religion, nationality, and marital status are mandatory fields. These would be illegal to ask for in most private-sector applications, but they are required by government notification formats.

Format is prescribed by the exam body notification

Each SSC, RRB, or State PSC notification specifies the exact format. Do not invent your own layout — follow the notification PDF.

The form doubles as your identity document at DV

At document verification, your printed bio-data is cross-checked field-by-field against original certificates. Any mismatch — even a middle name gap — can lead to rejection.

Hindi-medium candidates can fill in Devanagari where allowed

Most state PSC exams and some central exams (SSC, RRB) allow applications in Hindi. Check the notification for 'medium of application' (आवेदन का माध्यम).

SSC — CGL / CHSL / GD Constable / MTS

OTR-based registration at ssc.gov.in. Photo requirements: 4KB–12KB, JPG format, white background only. Signature scan: 1KB–12KB, blue or black ink on white paper. Name in OTR must exactly match 10th marksheet — even a middle name gap causes rejection at DV. Age relaxation: 3 years OBC, 5 years SC/ST. Zone/Region preference required for posting allocation.

RRB Railway — NTPC / Group D / ALP / Technician

Registration at rrbapply.gov.in. DV requires Aadhaar-based biometric authentication — your fingerprint or iris scan is verified against Aadhaar at the DV centre. If your Aadhaar name does not match the application form, biometric login fails and you cannot proceed. Community certificate must be in Central Government format (not state format) for Railway posts. Carry original Aadhaar + all certificates + 8–10 passport photos.

State Police — Constable / SI / ASI

Physical measurement details required: height (ऊंचाई), chest (सीना) with expansion, and weight (वजन). PET/PST results may be attached. Domicile/residence certificate (निवास प्रमाण पत्र) is mandatory — you can only apply for your state. Character certificate from local SP/DSP office required. Each state has its own recruitment portal and form format — check your state police recruitment board website.

State PSC — UPPSC / BPSC / MPPSC / RPSC

Application format varies by state commission. UPPSC uses uppsc.up.nic.in, BPSC uses bpsc.bih.nic.in, MPPSC uses mppsc.mp.gov.in. Most state PSCs allow Hindi (Devanagari) as the medium of application. Domicile certificate of the respective state is mandatory. Interview carries 75–200 marks depending on the state — your bio-data is the panel's primary reference document.

Defence — Army / Navy / Air Force Rally Entry

Uses prescribed bio-data form from joinindianarmy.nic.in. Additional fields: NCC certificate grade (A/B/C), sports achievements at national/state level, relationship certificate if applicable (son/brother of serving/ex-serviceman). Medical category SHAPE-1 required for most entries. For Agniveer entry, Aadhaar-linked registration is mandatory. Rally schedule and form available at joinindianarmy.nic.in.

Self-Attestation / स्व-प्रमाणन कैसे करें

Write 'Self-Attested' (स्व-प्रमाणित) on each photocopy, followed by your signature and the date. Use blue or black ink only. This is required at DV — unattested photocopies are not accepted.

Multi-page documents

Each page of multi-page documents (marksheets, degree certificates) must be attested separately. Do not just attest the first page.

Gazetted Officer attestation

Some state government exams and older notification formats still require attestation by a Gazetted Officer. Check the notification carefully — most central exams (SSC, RRB) now accept self-attestation. Source: Government of India OM on self-attestation policy.

Keep it consistent

Your signature on the declaration, self-attested documents, and the application form must all match. Inconsistent signatures raise identity verification flags at DV.

Step 1: Gather all original documents

Collect: 10th marksheet & certificate, 12th marksheet, graduation degree/provisional certificate, caste/category certificate (if applicable), EWS certificate (current FY), Aadhaar card, PAN card, domicile/residence certificate (for state exams), and passport-size photos.

Step 2: Verify name consistency

Compare your name across 10th marksheet, Aadhaar, PAN, and caste certificate. If there is ANY mismatch — even a spelling variation — get it corrected BEFORE applying. Aadhaar correction takes 7–15 days at an Aadhaar Seva Kendra.

Step 3: Get passport-size photos as per exam specs

Get photos taken against a white background. Ask the studio for both printed copies AND digital files in the exam's required file size (4KB–12KB for SSC, 10KB–50KB for RRB). Keep at least 10–12 identical photos.

Step 4: Fill personal details section

Use 10th certificate as the master reference. Write your name, father's name, DOB, and other details exactly as they appear on the marksheet. Do not transliterate — copy character by character.

Step 5: Fill educational qualifications table

Calculate percentage manually: (Marks Obtained ÷ Total Marks) × 100, rounded to 2 decimal places. Verify division: First (60%+), Second (45–59.99%), Third (33–44.99%). For CGPA, use your university's official conversion formula.

Step 6: Add work experience (if applicable)

Include exact joining and leaving dates (DD/MM/YYYY). If you have no experience, write 'Nil' (शून्य) — never leave blank. Include internships, apprenticeships, and contractual roles.

Step 7: Write the declaration

Copy the declaration text exactly as shown in Section 5 of this guide. Sign with blue or black ink. Write the place and date below your signature.

Step 8: Self-attest all photocopies

Write 'Self-Attested' (or 'स्व-प्रमाणित' in Hindi), your signature, and the date on every page of every photocopy. Use the same signature you used on the declaration and application form.

Step 9: Prepare 4–5 complete document packets

At DV, you submit one set and may need extras. Each packet should contain: bio-data, all self-attested photocopies (in order), passport photos, and the original admit card/call letter. Keep originals in a separate folder — they are shown for verification but not submitted.
