NJM Insurance Group, headquartered in the West Trenton section of Ewing Township, Mercer County, New Jersey, United States, offers personal auto, commercial auto, workers' compensation, homeowners, and umbrella insurance.[1] The company was formed in 1913 by a group of factory owners seeking workers' compensation coverage.[2][3] NJM has grown to provide insurance to more than 850,000 policyholders living in New Jersey and Pennsylvania.


NJM Insurance Group, originally known as New Jersey Manufacturers Casualty Insurance Company, formed as a workers’ compensation insurance company during the early 1900s, when industrialization in America was at its peak. The Company grew, expanding to auto insurance soon after being established in 1913.[1]

NJM began issuing dividends to policyholders in 1918, and has continued this practice in each subsequent year without interruption.[4] [5]

In 1921, New Jersey Manufacturers Association Fire Insurance Company was established by NJM to cover property loss, commercial auto accidents, private automobiles, as well as homes. This involved NJM in multiple lines of insurance. In 1951, the Company changed its name to New Jersey Manufacturers Indemnity Insurance Company, which combined auto bodily injury and property loss into one.[1]

The Indemnity Insurance Company was combined with the Casualty Insurance Company in 1965 to form today's New Jersey Manufacturers Insurance Company.

NJM’s main office has been in West Trenton, New Jersey, since 1966. Personal Lines and Commercial Lines Underwriting, General Claims and Medical Services Administration are headquartered there, as are most support services for Company operations. NJM has had additional offices in Northern New Jersey since the 1950s, and the Company's Northern New Jersey branch has been in Parsippany since 1996. The Southern New Jersey branch opened in Hammonton in 2000, providing customer service, claims, and sales operations for the company.[1]

In 2015, American soccer player Carli Lloyd was announced as NJM's spokesperson.[6]

In 2018, NJM expanded its services to Pennsylvania residents.[7]

Lines of business[edit]

The Company originally formed to provide workers' compensation insurance.

NJM partners with American Modern Insurance Group to offer coverage for motorcycles, ATVs, boats and, collector cars.[8]

NJM also provides homeowners, renters, umbrella, and commercial auto insurance.

The Company owns three insurance subsidiaries. The oldest subsidiary is New Jersey Re-Insurance Company (NJRe), which started writing policies in 1978 and currently provides workers' compensation, personal auto, and homeowners coverages, as well as umbrella insurance.[1][9]

The other two insurance subsidiaries were formed in 1999 to write coverage in the assigned risk markets – New Jersey Casualty Insurance Company for workers’ compensation and New Jersey Indemnity Insurance Company for personal auto.[1][9]
