National Insurance Company: India's Public Sector General Insurer Explained

National Insurance Company Limited — commonly searched as national insurance co or security national insurance — is one of India's four public sector general insurance companies owned by the Government of India. Established in 1906 and nationalised in 1972 under the General Insurance Business Nationalisation Act, National Insurance Company has operated for over a century as a provider of general insurance across motor, health, home, fire, marine and commercial insurance categories.

For policyholders, prospective buyers and anyone researching Indian insurance companies, understanding what National Insurance Company Limited is, what products it offers, how to access its services and how to evaluate its products against the full range of available options — including private sector competitors — is the practical knowledge this guide provides.

What National Insurance Company Limited Is

National Insurance Company Limited is a government-owned general insurance company — one of four public sector general insurers created through the nationalisation of the general insurance industry in 1972. The four public sector companies are National Insurance Company Limited, New India Assurance Company Limited, Oriental Insurance Company Limited and United India Insurance Company Limited. All four operate under the ownership of the Government of India and are regulated by IRDAI.

National Insurance Company is headquartered in Kolkata — making it historically the most prominent general insurer in eastern India, with deep roots in the Bengal business community and an extensive branch network across West Bengal, the Northeast and eastern Indian states alongside its national presence.

As a government-owned insurer, National Insurance Company carries the implicit institutional stability of sovereign backing — the same quality that makes government-owned insurers like LIC in life insurance attractive to buyers who prioritise institutional security over premium competitiveness or digital service innovation.

National Insurance Company is IRDAI-regulated like all licensed general insurers and is subject to the same product filing requirements, solvency standards, claims handling timelines and annual performance reporting obligations that apply to private sector insurers.

Products Offered by National Insurance Company

National Insurance Company offers a broad range of general insurance products across personal and commercial lines.

Health insurance is one of National Insurance Company's significant product categories. Under product names including Mediclaim, Mediclaim 2012 and various specialised health plans, National Insurance offers individual and family health insurance covering inpatient hospitalisation, pre and post-hospitalisation expenses, daycare procedures and other standard health insurance benefits. National Insurance is also a significant participant in government-sponsored health insurance schemes including Rashtriya Swasthya Bima Yojana and state government health schemes, which have historically given it meaningful group health insurance volumes alongside retail health products.

Motor insurance from National Insurance Company covers private cars, two wheelers and commercial vehicles under both third-party only and comprehensive coverage. The third-party motor insurance premium is IRDAI-regulated and identical across all insurers; the own-damage component is market-priced. National Insurance's motor insurance is distributed through its branch network, agents and increasingly through online channels.

Home and property insurance protects residential and commercial properties against fire, natural calamities, theft and other specified perils. National Insurance offers both standard fire and allied perils coverage and more comprehensive packages for home and business property.

Commercial and industrial insurance — covering fire, engineering, marine, liability and other commercial risks — has historically been a significant business line for National Insurance, particularly with industrial and commercial clients in eastern India.

Personal accident insurance and travel insurance round out the retail product portfolio.

National Insurance Company's Network and Distribution

National Insurance Company operates through a nationwide branch network spanning metropolitan cities, state capitals, district headquarters and smaller towns — giving it geographic reach in smaller cities and towns that many private sector insurers do not match through their own infrastructure.

For policyholders in eastern India — particularly West Bengal, Jharkhand, Bihar, Odisha and the Northeast — National Insurance's branch presence is among the most extensive of any general insurer, reflecting its historical headquarter city advantage and decades of operations in these regions.

Third-party agents and insurance brokers distribute National Insurance products in markets where the company has limited direct branch presence. Corporate clients may be serviced directly by the company's commercial teams.

National Insurance's digital capabilities — online policy purchase, renewal and policy servicing — have been developing alongside the broader insurance industry's digital transformation, though the pace of digital adoption has generally been faster in private sector companies than in public sector insurers.

How to Find National Insurance Company Near You

For policyholders who want to visit a National Insurance Company office — for claims, document submission, policy servicing or any other in-person need — the branch locator on the National Insurance Company official website provides office locations by state, city and area.

National Insurance's customer care helpline — available on the official website and on all policy documents — provides the telephone-based contact channel for claims notification, policy queries and service requests.

For health insurance claims processed through a TPA — third-party administrator — designated for the National Insurance policy, the TPA's contact details are on the health insurance card and in the policy document. The TPA handles cashless hospitalisation and reimbursement claim processing for National Insurance health policyholders.

For motor insurance claims, the nearest National Insurance branch coordinates the surveyor appointment after claim notification through the helpline or digital channels.

Evaluating National Insurance Company Against Other Options

For prospective buyers comparing National Insurance Company against private sector alternatives — ICICI Lombard, HDFC Ergo, Bajaj Allianz, Tata AIG and others for general insurance, or standalone health insurers for health insurance — the structured evaluation across objective criteria produces the most informed decision.

For health insurance specifically, the most important quality criterion is the health insurance claim settlement ratio — published annually in the IRDAI annual report. National Insurance's health claim settlement ratio should be verified from the most recent IRDAI annual report and compared against the ratios of competing health insurers. The local network hospital coverage in the specific city — verifiable through the National Insurance website's hospital search — confirms whether cashless care is accessible at preferred facilities.

For motor insurance, the motor claim settlement ratio from the IRDAI report and the local network garage coverage in the city of the vehicle's operation are the relevant quality criteria alongside the premium comparison.

For health insurance buyers specifically, the growing competitive strength of standalone health insurance companies — Star Health, Niva Bupa, Care Health Insurance and Aditya Birla Health Insurance — warrants inclusion in the comparison alongside National Insurance. Standalone health insurers' exclusive focus on health insurance builds deeper claims expertise, broader hospital networks and more specialised customer service than general insurers who manage health as one of several product lines.

The government ownership of National Insurance Company provides an institutional stability signal that some buyers weight heavily. For buyers who prioritise the implicit security of a government-owned entity — similar to the reasoning behind LIC preference in life insurance — National Insurance's public sector status is a genuine differentiator. This preference should be weighed against the observable performance data from the IRDAI annual report to ensure the institutional preference is backed by claims quality evidence.

National Insurance Company and Government Health Schemes

National Insurance Company has been a significant insurer for government-sponsored health insurance schemes — both at the central government level through RSBY and at the state government level through various state health protection schemes. These government scheme implementations have given National Insurance experience with high-volume group health insurance administration and relationships with public sector hospital networks across the country.

For individual buyers evaluating National Insurance for retail health insurance, the government scheme participation reflects operational scale but does not directly translate to retail individual policy quality. The retail product evaluation should focus on the specific retail health product terms and the claims settlement performance data.

Claims Process at National Insurance Company

For motor insurance claims, policyholders notify the National Insurance Company through the customer care helpline or the nearest branch. A surveyor is appointed to inspect the damaged vehicle and assess the repair cost. For cashless repairs at network garages, the insurer settles the bill directly with the garage. For repairs at non-network garages, the reimbursement claim process applies.

For health insurance claims, the cashless process applies at empanelled network hospitals through the designated TPA. The reimbursement claim process applies for non-network hospital treatment. The claim form and supporting documents — discharge summary, original bills, investigation reports and other documentation — are submitted to the TPA within the policy's specified timeframe.

For any claim dispute with National Insurance Company, the standard grievance escalation pathway applies — internal grievance officer, IRDAI IGMS escalation and the Insurance Ombudsman for disputes within its jurisdiction.
