National Independent Statistical Service

What National Independent Statistical Service does

National Independent Statistical Service (NISS) is a non-profit membership organization founded in 1962 and headquartered in Indianapolis, Indiana, that collects, validates, and files statistical data on behalf of property and casualty insurance companies to satisfy state and federal regulatory reporting requirements. It is a licensed Statistical Agent in all U.S. states except Texas, plus Washington D.C. and Puerto Rico, and processes 8,884 compliance reports annually across $38B in total reported premium. The organization serves P&C writers across automobile, commercial lines, homeowners, general liability, and other lines (excluding workers compensation), and files compiled data with state insurance departments, NAIC, and AIPSO for assigned risk programs.

NISS's core technology is a web-based member portal with secure file upload (Data Calls, Supplemental Calls, Affidavits), the Online Edit Utility for pre-submission data validation, a Submission Status Grid, Timeliness Reports, and Compilation Reports that provide aggregated industry benchmarks. Supporting products include codified Statistical Plans (Auto Volume I/II, Commercial Lines, Homeowners, Other Than Auto), Territory Listings by ZIP Code, and the Fast Track Utility for benchmarking. All editing and reporting use NISS's proprietary edit tables, codes, and reports; no public API exists, and data is submitted through web forms and file uploads. The organization operates with 11-50 employees averaging 25 years of industry experience.

Revenue is generated through annual membership assessments based on data submitted to A.M. Best, described as the lowest in the industry with documented 80%+ savings versus alternatives. Pricing is custom and not publicly disclosed; NISS charges no fines or fees for late or imperfect submissions. Go-to-market combines direct member sales (email, phone, demo accounts), industry conference presence (NAMIC, InsureTech Connect, Insurtech Insights, TMPAA), educational content via the NISS News newsletter and website resources, and an annual NISS Workshop for training. Only one rate increase has been implemented since 1989, signaling a stable, low-cost operating model.
