Pros and cons of large car insurance companies

Large insurance companies tend to have more customer service and technological resources than their smaller competitors.

This usually makes it easier to shop, manage your policy and file a claim with a large company. It doesn’t always translate into lower rates, though.

Depending on your driving record, ZIP code, age and other rate factors, a small or midsize company may offer you a lower rate than a large company.

Size is also not the only factor that determines a company’s ability to provide quality customer service.

In J.D. Power’s 2023 claims satisfaction rankings, midsize car insurance companies occupy four of the top five positions. The highest rated company, Amica Mutual, ranks 22nd for size.

These are the main reasons to compare car insurance quotes from companies of all sizes when you shop.

Do major car insurance companies use the same agents?

Major car insurance companies do not all use the same insurance agents. Slightly more than half have captive agents, who only represent their own company. The rest work with independent agents, who can quote and sell policies from multiple companies.

State Farm and Allstate are among the largest captive car insurance companies. You can only get a quote from one of their exclusive agents. You usually get paired with one when you request a quote online or by phone.

Companies that work with independent agents also make it easy to get quotes and find a nearby agent by phone or online. Although independent agents can quote policies from a few different companies, they can’t provide quotes from a captive company such as State Farm.

Captive vs. independent insurance agents

Agent typeProsCons
CaptiveHas thorough knowledge of their company’s coverages and discounts.You have to contact captive agents separately to compare each company’s quotes.
IndependentCan compare quotes from multiple companies for you.Can’t get quotes from companies with captive agents.

Of the top 10 largest car insurance companies, these companies have captive agents:

  • Allstate
  • American Family
  • Farmers
  • Geico
  • State Farm
  • USAA*

Most captive companies require their agents to have offices in the communities they serve. The exceptions are Geico and USAA, which largely rely on phone and online services.

These major auto insurance companies work with independent agents:

  • Liberty Mutual
  • Nationwide
  • Progressive
  • Travelers

Progressive also makes it easy to buy car insurance directly from its website, without an agent.

Methodology

Auto insurance company rankings are based on total U.S. premiums written, or amounts billed, in 2023, according to the NAIC.

Overall satisfaction ratings are from the J.D. Power 2023 U.S. Auto Insurance Study. Claims ratings are from the J.D. Power 2023 U.S. Auto Claims Satisfaction Study.

Complaint ratings are based on the NAIC’s Complaint Index, which tracks confirmed, or substantiated, complaints. A 2.0 rating means a company has twice as many confirmed complaints as expected for its size. A 0.5 rating means it has half as many.

LendingTree obtains rates from Quadrant Information Services using publicly sourced insurance company filings. Rates are based on an analysis of hundreds of thousands of car insurance quotes for a typical driver. Your own rates may be different.

Unless otherwise noted, quotes are for a full-coverage policy for a 30-year-old man with good credit and a clean driving record. He drives a 2015 Honda Civic EX.

Full-coverage policies include:

  • Bodily injury liability: $50,000 per person, $100,000 per accident
  • Property damage liability: $25,000
  • Uninsured motorist: $50,000 per person, $100,000 per accident
  • Personal injury protection: Minimum limits where required
  • Collision: $500 deductible
  • Comprehensive: $500 deductible

Liberty Mutual’s rates are not available through Quadrant.

*USAA is only available to current and former members of the military and their families.
