How to Link Aadhaar with Birth Certificate Online: A Complete Guide

October 7, 2026

Under the Registration of Births and Deaths (Amendment) Act, 2023, the birth certificate is established as the primary proof of birth in India, and Aadhaar is officially recognized for birth reporting. If you are looking to link these two crucial identity documents, the most important detail to understand is that there is no centralized, nationwide UIDAI online portal to link an existing birth certificate to an Aadhaar card.

Instead, two valid mechanisms exist to achieve this integration. First, the Aadhaar-Linked Birth Registration (ALBR) system automates the process for newborns (0 to 5 years) directly at birth. Second, for older or existing certificates, decentralized state-level portals (such as Rajasthan’s Pehchan portal) provide specialized online tools to link the records. This guide explains how to navigate both options safely and legally.

Is Online Aadhaar and Birth Certificate Linking Available Nationwide?

There is a widespread misconception that any citizen can log into a single central government website and link their birth certificate with their Aadhaar card. This is not the case. Centralized self-service linking is currently unavailable across India. Instead, linking existing records is managed entirely at the state level using decentralized databases.

Because there is no single national portal, citizens must rely on their respective state’s civil registration utilities if they wish to perform this process online. Due to the high search volume for this service, multiple fraudulent websites mimic official government registration portals. It is critical to use only authorized official state domains and avoid sharing sensitive personal information or Aadhaar details on unverified third-party websites.

How to Link Aadhaar with Birth Certificate Online (State-Specific Portals)

Citizens whose state databases support digital linking can complete the process online. Rajasthan’s Pehchan web portal serves as a verified model of how this decentralized system operates. To link an existing birth certificate online through this method, your records must already exist on your state’s digital database, and you must have a valid Birth Registration Number (BRN).

If you are registered in a state offering this digital utility, follow these verified steps to execute the link:

Open the official state civil registration portal (for example, the official Pehchan web portal in Rajasthan).
Locate and select the specific option for Aadhaar linking, such as ‘NEW पंजीकरण मे आधार लिंक’ (Aadhaar Link in Registration).
Enter the unique Birth Registration Number (BRN), the registration year, and the individual’s 12-digit Aadhaar number.
The portal will trigger a One-Time Password (OTP) to the mobile number registered with the Aadhaar card.
Enter the OTP on the portal to complete the identity verification and submit the linking request.

Aadhaar-Linked Birth Registration (ALBR) for Newborns

For newborns and children under the age of 5, the Government of India has introduced the Aadhaar-Linked Birth Registration (ALBR) system. This system integrates birth registration directly with Aadhaar enrolment, ensuring a seamless digital identity from birth. Over 16 states have already established ALBR systems at medical institutions to automate this process.

The standard ALBR process flows as follows:

Recording Birth Details: When a child is born in a participating medical institution, the hospital records the birth details directly on the central Civil Registration System (CRS) portal.
BRN Generation: The local registrar processes the entry and generates a unique Birth Registration Number (BRN).
Aadhaar Enrolment: A certified operator initiates the child’s Aadhaar enrolment on-site using the Child Enrolment Lite Client (CELC) mobile application.
Parental Linking: The operator links the child’s new record directly to the parent’s or guardian’s Aadhaar card. Biometric data is not captured for children in this age group.

Eligibility and Document Requirements

To use either the online state portals or the newborn ALBR system, you must meet specific eligibility criteria and provide the correct documentation. The requirements are designed to maintain strict security and verification standards.

For Newborns (ALBR / Bal Aadhaar Enrolment):

The child must belong to the 0 to 5 years age group.
At least one parent or legal guardian must hold a valid, active Aadhaar card.
No biometric data (fingerprints or iris scans) is captured for children under 5 years; the child’s identity is linked directly to the parent’s or guardian’s Aadhaar.
Bal Aadhaar enrolment for children under 5 is completely free of cost.

For Existing Certificates (State Online Portals):

The existing birth certificate must be registered and active within the state’s digital database.
You must have the official Birth Registration Number (BRN).
The applicant (or parent) must have an active mobile number registered with UIDAI to receive Aadhaar-based OTP verifications.
Authorized state online self-service linking utilities are free of cost for citizens.

Key Benefits of Linking Aadhaar with Birth Certificate

Associating these two foundational documents provides several key benefits for citizens and public administration alike:

Seamless Identity Management: It establishes a continuous, secure digital identity from birth, making it much easier to register for government school admissions, obtain passports, and access social welfare schemes.
Prevention of Duplication: The integration helps eliminate duplicate identity records and prevents database duplication across municipal and state registries.
DigiLock Retrieval: Linking your birth certificate with your Aadhaar makes it incredibly simple to pull your official digital birth records directly into Digilocker using your linked credentials.

Alternative Offline Linking Methods

If your state does not currently offer an online database linking utility like Rajasthan’s Pehchan portal, you cannot link the documents online. In such cases, you must use official offline channels:

Local Registrar Visit: You can contact your local municipal corporation office or gram panchayat registrar. Bring physical copies of your Aadhaar card, the original birth certificate, and your registered mobile phone to complete the linking manually.
Doorstep Post Office Services: For child enrolment, the India Post Payments Bank (IPPB) offers convenient doorstep Child Enrolment Lite Client services. You can schedule an appointment to have a certified postal representative visit your home to register your child’s Bal Aadhaar and link it with their birth record.

Important Legal Guidelines and Security Protections

When handling identity documents, it is important to understand the legal boundaries and privacy protections established by Indian law:

No Correction of DOB via Aadhaar: An Aadhaar card itself is not legally accepted as valid proof for correcting an official Date of Birth on a birth certificate. The birth certificate remains the ultimate legal authority on your birth date.
Strict Privacy Rules: No government office, school, or digital portal is permitted to publicly display a resident’s 12-digit Aadhaar number. Furthermore, Aadhaar numbers must not be displayed publicly on final, printed birth certificates for privacy reasons.

Frequently Asked Questions

Can I link my old birth certificate with Aadhaar online if I live in any state?

No. A centralized, nationwide online self-linking service does not exist. You can only link your existing birth certificate online if your specific state government provides a dedicated tool (such as Rajasthan’s Pehchan portal). If your state does not provide an online portal, you must visit your local municipal or panchayat registrar office to complete the process offline.

Is a child’s biometric data required for Aadhaar-linked birth registration?

No. Biometric data (fingerprints and iris scans) is not collected for children under the age of 5. The enrolment process requires only the child’s basic demographic details, a photograph, and a link to the parent’s or guardian’s valid Aadhaar card.

What should I do if there is a name mismatch between my Aadhaar and my Birth Certificate?

If there is a name mismatch, the secure linking process will fail during the verification stage. You must first resolve the discrepancy. Update your name on your Aadhaar card through the UIDAI portal, or apply for a formal correction on your birth certificate through your state’s civil registry before attempting to link the two documents.

Conclusion

While a single, centralized nationwide portal to link an existing birth certificate to Aadhaar online does not exist, citizens can successfully link these records through secure, decentralized state-level systems or the automated Aadhaar-Linked Birth Registration (ALBR) process for newborns. Always protect your personal information by using only official state registry portals or verified offline government offices to keep your digital identity secure.
