Births in Kolkata are registered by the Kolkata Municipal Corporation (KMC), which is the Registrar of Births and Deaths for the city under the Registration of Births and Deaths Act, 1969. To get or download a certificate you apply at the KMC borough health office or through its online service, with the hospital's birth report, an identity proof of the parents and proof of address. Registration is free of charge if the birth is reported within 21 days.
Who registers a birth in Kolkata
The KMC is the registering authority for the whole city. The hospital or nursing home where the child is born sends a birth report to the corporation under Section 8 of the Act. For a home birth, the parents or the person who attended the birth must give the information to the KMC within 21 days. The KMC is divided into boroughs, and each borough's health department keeps the birth register for its area. When you apply for a certificate you apply to the borough office that covers the address where the birth occurred.
A birth certificate is a permanent record that a child was born. It is accepted across India as proof of age and identity, and it is needed for school admission, a passport, Aadhaar enrolment for a minor, and for many government schemes and scholarships. Because the KMC register is the primary record, getting the entry right at the time of birth saves years of correction later.
How long you have to register
The Registration of Births and Deaths Act, 1969 and the state rules set out a sliding scale for late registration. The later you are, the more permission you need:
| Delay after birth | What is required |
|---|---|
| Within 21 days | Registered free of charge. |
| 21 days to 30 days | Registered on payment of a late fee. |
| 30 days to 1 year | Registered only with the written permission of the prescribed authority, on a late fee and usually an affidavit. |
| After 1 year | Requires an order of a First Class or Executive Magistrate, plus a late fee. |
The exact late fee depends on the length of the delay and the schedule in force, so confirm the amount at the KMC counter or on the portal rather than relying on an old figure. An affidavit on stamp paper is often asked for in the late-registration routes.
Documents you need
Keep the originals for verification and a set of photocopies for the file. The usual set is:
- The hospital birth report or discharge summary that names the child and the parents.
- The hospital card or admission slip.
- Identity proof of both parents — Aadhaar, voter ID or passport.
- Address proof of the parents.
- The marriage certificate of the parents, where available, which helps match surnames.
- For a home birth, a certificate from the doctor, midwife or the person who attended the birth.
- An affidavit where registration is late.
For an adult applying for their own certificate years later, an affidavit stating the facts of birth and the address where the birth took place is often required, along with any school records or other proof of date of birth. Where the parents' names were not recorded at the time, or one parent is no longer traceable, the KMC may ask for additional proof before it makes the entry.
Apply online or at the KMC office
The KMC provides an online counter for birth and death registration and certificates, and the state's e-District service also links several civic certificates. Online usually works best when the birth is already registered and the record can be searched; a fresh or delayed registration is often smoother at the borough office, because the health department verifies the hospital record there. Take a token, submit the form and documents, and note the acknowledgement number you are given. Keep that number — you will need it to collect the certificate or to follow up if it is delayed.
How to download the certificate
If the birth is registered, the download route follows a short sequence:
- Open the KMC birth and death portal and choose the birth certificate service.
- Enter the registration number, the date and place of birth, and the parents' names.
- Choose the borough or registration unit, then search the register.
- If the record is found, pay the prescribed certificate fee online and download the digitally issued certificate.
- If the record is not found, the birth may never have been registered, or the details entered online differ from the register. Apply at the borough office with the hospital report rather than retrying online.
Check the certificate as soon as you have it. The name, the date and place of birth, the sex and the parents' names should match the hospital record exactly. A small mismatch caught at once is a simple correction; the same mismatch found years later, at a passport interview, becomes a much longer process.
Where a certificate is not available online you can apply in person: fill the application form, attach the documents, pay the fee and collect the certificate, usually within a few working days. A family member can collect it on your behalf with an authority letter and identity proof.
Fees and how long it takes
The fee for a birth certificate is a small prescribed sum, and a search fee may be charged if the record has to be located in the register. Because the state revises the schedule from time to time, the exact amount should be confirmed at the KMC counter or on the portal rather than taken from an old figure. A late-registration fee is separate from the certificate fee and grows with the delay.
If the birth is already registered and the record is searchable online, the digital certificate can often be downloaded the same day. A fresh registration, a late entry or a correction takes longer, usually a few working days to a few weeks depending on the borough's workload.
Correcting a mistake in the certificate
Mistakes such as a misspelt name, a wrong date of birth or the wrong sex are common. The KMC can correct the register on an application supported by the hospital record and an affidavit; some changes after a long delay need a court or magistrate order. Never overwrite or alter a certificate by hand — an altered certificate is treated as invalid, and the correction must be made in the register itself. If the birth certificate is refused or delayed without reason, a written representation to the borough health officer is the first step, and further remedy lies before the appropriate authority under the Act. Guidance on the paperwork is available through a free consultation.
Common problems people face
A few problems come up again and again at the KMC counter:
- The name of the child was not given at the time of birth, so the certificate shows only the sex or a blank name. The name can be added later on an application.
- The parents' names are entered with a spelling that does not match their Aadhaar, which causes trouble at a passport office or school. Apply for a correction rather than accepting the mismatch.
- The hospital where the birth took place has closed or shifted and the birth report is hard to obtain. A request to the hospital's records section, or an affidavit explaining the position, is the fallback.
- The address in the register is old and the applicant now lives elsewhere. The certificate records the place of birth, not the current address; that is normal and not an error.
Where the borough office turns down a request, ask for the reason in writing. That record is the base for any later representation or application.
If the birth was never registered
Where more than a year has passed and no entry exists, registration needs an order of a First Class or Executive Magistrate directing the Registrar to register the birth, together with a late fee and evidence such as the hospital report, school records, the parents' affidavits and identity documents. This is the route many adults take to obtain a birth certificate for a passport or a government job. The magistrate must be satisfied that the birth in fact took place and that no earlier entry exists.
