Northwestern Mutual Headquarters & Corporate Office

About Northwestern Mutual

Northwestern Mutual is a major U.S. financial-services organization headquartered in Milwaukee, Wisconsin. The company traces its history to 1857 and today provides life insurance, disability income insurance, long-term care-related coverage, annuities, financial planning, investment brokerage, wealth management, trust services, and institutional investment capabilities. Unlike a conventional publicly traded insurer, Northwestern Mutual operates under a mutual company structure, which means it does not have outside public shareholders in the traditional sense and focuses on serving policyowners and clients.

The company has grown into one of the largest financial institutions in the United States. In its 2025 annual reporting, Northwestern Mutual said it had more than 5 million clients, nearly $2.5 trillion of life insurance protection in force, more than $400 billion in retail investment client assets, and total company assets approaching $400 billion. It also reported record 2025 revenue of more than $41 billion and entered 2026 with over $42 billion in surplus and asset valuation reserve, reflecting the financial strength of its insurance operations.

Northwestern Mutual continues to be headquartered in downtown Milwaukee and is currently led by Timothy J. Gerend, who became Chief Executive Officer at the beginning of 2025. The company combines insurance protection with investment and financial-planning services, while its subsidiaries include Northwestern Mutual Investment Services, LLC and Northwestern Mutual Wealth Management Company. Its Milwaukee headquarters and related corporate operations remain central to the company’s long-term strategy and advisor network.

Northwestern Mutual Products & Services

Life Insurance

Northwestern Mutual offers permanent and term life insurance designed to provide financial protection for beneficiaries after the insured person’s death. The company is one of the largest direct providers of individual life insurance in the United States and reported nearly $2.5 trillion of life insurance protection in force in 2025.

Whole Life Insurance

Whole life insurance provides permanent coverage with a guaranteed death benefit subject to policy terms and may build cash value over time. Eligible participating policies may also receive dividends, although dividends are reviewed annually and are not guaranteed.

Term Life Insurance

Term life insurance provides coverage for a defined period and is generally used for temporary protection needs such as family-income protection, mortgages, education costs, or business obligations. Coverage can often be coordinated with permanent insurance as part of a broader financial plan.

Disability Income Insurance

Northwestern Mutual offers disability income insurance designed to replace a portion of income if an insured person becomes disabled and is unable to work. The company provides dedicated disability claim support and online claim forms for qualifying policyowners.

Long-Term Care Insurance

Northwestern Mutual Long Term Care Insurance Company provides long-term care coverage for qualifying policyowners. Claims support is available through a dedicated long-term care administration team that assists with claim initiation, documentation, and benefits questions.

Annuities

Northwestern Mutual offers annuity products designed to support long-term savings and retirement-income goals. Depending on the product, annuities may provide tax-deferred accumulation, guaranteed income features, or other retirement-related benefits.

Financial Planning

Financial advisors work with clients to develop plans covering protection, savings, retirement, investments, estate considerations, and other financial goals. The company’s model combines insurance and investment products rather than treating them as entirely separate planning needs.

Investment Brokerage

Northwestern Mutual Investment Services, LLC provides brokerage services for securities and investment products. Clients can hold and manage qualifying investment accounts through the company’s broader financial-planning relationship.

Wealth Management

Northwestern Mutual Wealth Management Company provides investment advisory and wealth-management services. The company reported more than $400 billion in retail investment client assets at the end of 2025.

Trust Services

Northwestern Mutual provides trust and private-client services through its wealth-management organization. These services can support estate planning, asset administration, multigenerational wealth strategies, and other complex financial needs.

Retirement Planning

Advisors help clients evaluate retirement-income needs, savings strategies, insurance coverage, investment allocation, Social Security timing, and long-term spending goals.

Education Planning

Financial advisors can help families evaluate savings strategies for college and other education costs. Education planning may involve investment accounts, insurance coordination, and broader cash-flow planning.

Estate Planning Support

Northwestern Mutual advisors work with clients and their legal or tax professionals to coordinate insurance, investment, beneficiary, trust, and estate-planning strategies.

Business Planning

The company supports business owners with succession planning, key-person insurance, executive benefits, retirement planning, and other strategies designed to protect businesses and owners.

Northwestern Mutual Mobile App

The Northwestern Mutual app allows clients to review insurance policies, investment accounts, payments, and linked financial accounts from supported mobile devices. Customers can also track aspects of their financial picture and manage qualifying account functions digitally.

How to Reach a Real Person at Northwestern Mutual

For most policy, billing, account, beneficiary, website, or general-service issues, call 866-950-4644 Monday through Friday from 7:00 AM to 6:00 PM Central Time. Have your policy number, account number, full name, date of birth, and details of the issue ready. If the question concerns an investment account, ask to be transferred to the Investments team. If you already work with a Northwestern Mutual financial advisor, contacting that advisor can also help with planning-related matters and product servicing.

For claims or specialized insurance issues, use the dedicated department rather than the general line. Disability and long-term care claims can use 800-748-9493, annuity servicing uses 888-455-2232, and certain life or disability policy security requests use 800-388-8123. Keeping the policy number, claim documents, medical information requested by the insurer, beneficiary documents, and previous case references ready can reduce delays.

If the matter involves a local financial representative rather than corporate policy administration, contact the representative’s office first and document the response. Corporate Customer Service is more appropriate when the concern involves company records, billing, claims administration, online access, or an issue that cannot be resolved through the advisor’s office.

How to File a Complaint Against Northwestern Mutual

Complaints can involve insurance claims, billing, policy administration, financial-advisor conduct, investment transactions, privacy, annuities, disability or long-term care claims, or online-account problems. Before escalating, gather the policy or account number, statements, transaction confirmations, claim documents, correspondence, advisor information, dates, and any prior case numbers.

Step 1: Contact Customer Service

Begin with Northwestern Mutual Customer Service at 866-950-4644. Explain the complaint clearly, provide the relevant policy or account number, and ask the representative to document the issue. For claims, billing, beneficiaries, or account-access concerns, provide the exact date the problem occurred and any written correspondence you have already received. Keep the representative’s name and any reference number associated with the call.

Step 2: Contact the Relevant Department

Use the specialized department when the issue involves a particular product. Disability and long-term care complaints can begin through 800-748-9493, annuity issues through 888-455-2232, and investment-account issues through 866-950-4644 with a request for the Investments team. Matching the complaint to the correct department reduces unnecessary transfers and ensures that specialists familiar with the product can review the issue.

Step 3: Request Supervisor or Management Review

If the first representative cannot resolve the issue, ask for supervisor, claims-management, account-management, or compliance review. Provide the earlier case number and a short written chronology showing what happened, what Northwestern Mutual previously communicated, and what resolution you are requesting. If the complaint involves an advisor or representative, identify the person’s office and the dates of relevant meetings or transactions.

Step 4: Use the Company’s Written Complaint Channel

For a complaint that requires documentation, submit the issue in writing and retain copies. Privacy or data-accuracy matters can be directed to Northwestern Mutual’s Privacy Office at 720 East Wisconsin Avenue, Milwaukee, WI 53202. Written complaints should include policy or account identifiers, dates, copies of relevant correspondence, and a specific requested resolution.

Step 5: Contact Corporate Headquarters

If internal service channels do not resolve the issue, send formal correspondence to The Northwestern Mutual Life Insurance Company, 720 East Wisconsin Avenue, Milwaukee, WI 53202. Include your full contact details, policy or account number, previous complaint history, case references, and supporting documents. Sending copies rather than original documents and using a trackable delivery method is advisable for important disputes.

Step 6: Use the Specialized Complaint or Dispute Department

For investment-related concerns involving brokerage or advisory services, request compliance review through the relevant Northwestern Mutual investment entity. Claims disputes should be escalated through the applicable insurance claims department. Concerns involving internal business conduct can also be reported through the Ethics Resource Center at 866-663-8427, depending on the nature of the issue.

Step 7: File With the Appropriate Regulator

Insurance complaints can generally be submitted to the insurance department in the state where the policyowner resides or where the policy was issued. Investment or securities complaints may fall under FINRA, the U.S. Securities and Exchange Commission, or a state securities regulator depending on the product and entity involved. Provide the regulator with policy documents, statements, complaint correspondence, and Northwestern Mutual’s written response.

Step 8: Use Consumer Protection or Financial Dispute Options

If the complaint involves payment, unauthorized transactions, privacy, or another consumer-financial issue, additional options can include the customer’s financial institution, card issuer, state Attorney General, or other applicable consumer-protection authority. Investment customers may also use FINRA’s investor complaint process when relevant. The best route depends on whether the underlying issue is insurance, securities, privacy, billing, or advisor conduct.

Step 9: Consider Formal Legal or Arbitration Procedures

If regulatory and internal complaint channels do not resolve the dispute, review the applicable insurance policy, brokerage agreement, advisory agreement, or other contract for arbitration, mediation, litigation, and limitation provisions. Before starting a formal proceeding, preserve all statements, claim determinations, policy documents, advisor communications, and complaint records. For significant financial disputes, consulting a qualified attorney familiar with insurance or securities law may be appropriate.
