What Happens When You Get the Rejection Email?
“Your medical certificate does not meet required standards. Please resubmit.” Ankit stared at the email from HR. He’d submitted a certificate from a qualified doctor. It had his name, the dates, and a diagnosis. What was wrong with it? He called HR. The answer: “The doctor’s registration number is missing.” That one missing element meant his sick leave was rejected and marked as unauthorized absence. If you’ve ever wondered what medical certificate format Indian companies actually accept, or why some certificates get rejected while others sail through HR approval, this guide explains exactly what works.
What Indian Law Requires
There’s no single prescribed “official medical certificate format” mandated by central Indian law. However, various state Shops and Establishments Acts and employment laws establish certain requirements. Core legal requirements across most states:
- Certificate must be from a registered medical practitioner (MBBS or MD)
- Must state the nature of illness
- Must specify the period of absence recommended
- Must be signed by the doctor
Beyond these basics, the specific format varies by company and sometimes by purpose (sick leave vs fitness certificate vs medical examination).
Universal Elements Every Medical Certificate Must Have
Regardless of purpose or company, these elements are non-negotiable:
-
Doctor’s Credentials
Must include:
- Full name of doctor
- MBBS or MD qualification clearly mentioned
- Medical council registration number (this is critical)
- Specialization if relevant (e.g., “MD General Medicine”)
Why it matters: HR teams verify doctor credentials against State Medical Council or National Medical Commission databases. Without a registration number, verification is impossible. Common mistake: Certificates that just say “Dr. Rajesh Kumar, MBBS” without the registration number get rejected.
2. Clinic/Hospital Information
Must include:
- Name of clinic or hospital
- Address
- Contact number (phone/mobile)
- Official letterhead or stamp
Why it matters: Establishes authenticity. Helps HR verify if needed. Common mistake: Handwritten certificates on plain paper without clinic details look unprofessional and suspicious.
3. Patient Information
Must include:
- Patient’s full name (exactly as per company records)
- Age (optional but recommended)
- Gender (optional)
- Employee ID (if provided to doctor)
Why it matters: Name must match company database exactly. “Ankit Kumar” vs “Ankit K” vs “A. Kumar” can cause issues. Common mistake: Using nicknames or shortened versions of names that don’t match official records.
4. Date of Examination
Must include:
- Clear date when doctor examined the patient
- Format: DD/MM/YYYY or DD-Month-YYYY
Why it matters: HR needs to know the certificate is recent and relates to the absence period. Common mistake: Ambiguous dates like “15/10/23” (is it October 15 or 10th of 15th month?). Use “15-Oct-2023” format for clarity.
5. Period of Illness
Must include:
- Specific date(s) of illness
- OR date range (e.g., “17th Feb to 19th Feb 2026”)
Why it matters: Must align with the dates you claimed sick leave. Common mistake: Vague statements like “patient was unwell for a few days” without specific dates.
6. Diagnosis or Nature of Illness
Must include:
- Medical diagnosis (can be general like “Acute Viral Fever” or “Acute Gastroenteritis”)
- OR symptoms if diagnosis isn’t definitive (e.g., “Fever with body ache”)
Why it matters: Establishes medical reason for absence. Need not be overly detailed (patient privacy). Common mistake: Either too vague (“patient was sick”) or too detailed (violating patient privacy with extensive medical history).
7. Rest Recommendation
Must include:
- Clear statement like “Advised rest for X days”
- Specific number of days
- Can mention “fit to resume work from [date]”
Why it matters: Justifies the number of sick leave days you’re claiming. Common mistake: No rest recommendation, just diagnosis. HR needs the doctor’s professional opinion on needed rest periods.
8. Doctor’s Signature and Stamp
Must include:
- Doctor’s physical signature (digital signatures acceptable from recognized platforms)
- Official clinic/hospital stamp with doctor’s name
- Date of certificate issuance
Why it matters: Authentication. Unstamped, unsigned certificates are automatically rejected. Common mistake: Illegible signature, missing stamp, or unclear stamp that can’t be read.
9. Addressed To
Should include:
- “To Whom It May Concern” (most common and safest)
- OR “To: The HR Manager, [Company Name]”
- OR “To: The Employer” (generic)
Why it matters: Professional formatting. Some companies require it addressed to them specifically. Common mistake: Not addressing to anyone, making it look like a personal medical document rather than an employment certificate.

Common Formatting Mistakes That Lead to Rejection
-
Mistake 1: Missing Registration Number
Why rejected: Cannot verify doctor is qualified and registered. Fix: Always include registration number. Format: “Registration No: 12345/Karnataka Medical Council” or “NMC Reg: 67890”
-
Mistake 2: Unclear or Generic Diagnosis
Example of bad format: “Patient was unwell and needed rest” Why rejected: Too vague, doesn’t establish medical reason Fix: Use specific terms: “Acute Viral Fever”, “Acute Gastroenteritis”, “Migraine”, etc.
-
Mistake 3: Date Mismatches
Example: Certificate dated 20th Feb, but you claimed sick leave on 17th Feb Why problematic: Suggests you got certificate after the fact Fix: Get certificate during illness period. If delayed, doctor should note “Patient was examined on [earlier date] and advised rest from [dates]”
-
Mistake 4: No Letterhead or Stamp
Why rejected: Looks informal, difficult to verify authenticity Fix: Certificate must be on clinic letterhead or have official stamp with clinic details
-
Mistake 5: Illegible Signature or Details
Why rejected: HR cannot read doctor’s name or registration number Fix: Typed certificates with clear printed doctor details preferred. Signature can be handwritten but name should be typed/printed
-
Mistake 6: Wrong Doctor Qualification
Example: Certificate from BAMS (Ayurveda) or BHMS (Homeopathy) doctor Why rejected: Most company policies and state laws specify “registered medical practitioner” meaning MBBS/MD Fix: Get certificate from MBBS or MD qualified doctor
-
Mistake 7: Excessive Medical Detail
Example: Full medical history, test results, detailed symptoms Why problematic: Privacy concerns, more detail than needed for employment purposes Fix: Keep diagnosis general and professional. “Acute Viral Fever” is sufficient – don’t need full case history
-
Mistake 8: No Rest Duration Specified
Example: “Patient is sick” without saying how many days rest needed Why rejected: HR needs to know how many days of sick leave are medically justified Fix: Clear statement: “Advised rest for 3 days from 17-19 Feb 2026”
Digital vs Physical Certificates
| Digital Certificates (PDF) | Physical Certificates |

Requirements for acceptance:
Most IT companies, startups, modern corporations: Prefer digital certificates (faster, easier to process) |
Still preferred by:

Tip: Even if you get physical certificate, take high-quality photo/scan for digital backup |
Letterhead vs Plain Paper

Why letterhead matters:
|
Plain paper certificates:
Best practice: Always insist on letterhead. If the doctor doesn’t have a letterhead, ensure an official stamp with complete details is present. |
Language: English vs Regional Languages
| English certificates | Regional language certificates (Hindi, Tamil, Telugu, etc. |
|
|
Recommendation: Request English certificate when possible. If a regional language certificate is all that’s available, get it but be prepared to provide translation if requested.
Special Format Requirements
Form 1A (Driving Licence Medical)
It has a government prescribed format that we cannot deviate from. Deviation of the certificate format can lead to rejection of the application. One must use the exact Form 1A template as provided from the Ministry of Road Transport and Highways,
Insurance Claim Certificates
People may need a specific format provided by the insurance company. Usually requires more detail than employment sick leave certificates.
Visa Application Certificates
Different countries have different requirements. Check specific embassy/consulate requirements.
Pre-Employment Medical
Some companies provide their own format. If provided, use that. If not, the fitness certificate format works.
