Allstate headquarters is at 3100 Sanders Road, Northbrook, Illinois — but not the sprawling campus most people picture. The insurer sold the bulk of its 1967 Northbrook complex in 2022 and consolidated its corporate office in the one building it kept, and it never followed through on a much-discussed move to downtown Chicago. Below you will find everything you need to reach the company: the current corporate office address, the 24/7 customer service and claims phone numbers, the correct mailing addresses for claims and payments, and the escalation steps that actually work when a claim stalls.

Allstate Headquarters Location and Contact Information
The Allstate Corporation is headquartered at 3100 Sanders Road, Northbrook, IL 60062, about 25 miles north of downtown Chicago. That is the address of principal executive offices on the company’s most recent quarterly report to the SEC (the 10-Q for the quarter ended June 30, 2026), and it is the “Allstate Corporate Address” listed on the company’s own contact page. The corporate switchboard listed on SEC filings is (847) 402-2800.
The address deserves a word of explanation, because it changed. Allstate moved to Northbrook in 1967, into a 122-acre, six-building campus centered on 2775 Sanders Road. In late 2021 the company agreed to sell the majority of that campus — about 2 million square feet across five Sanders Road addresses — to Dermody Properties for roughly $232 million, with the deal closing in 2022 and the old office buildings since demolished for logistics use. Allstate kept the building at 3100 Sanders Road, which became its corporate headquarters. In January 2022 the company also bought an office tower at 29 North Wacker Drive in Chicago’s Loop as a possible new headquarters, but it never moved in and sold that building in 2024. So despite the headlines, Allstate’s headquarters remains in Northbrook.
Keep in mind that the corporate office is an executive location, not a service center. Allstate states plainly that the Northbrook address “doesn’t receive mail,” so claims documents, payments and complaint letters sent there will not reach anyone useful. Use the phone lines, the app, or the mailing addresses listed further down instead.
Phone Contacts
Allstate runs separate lines for sales and service, claims, roadside and billing, and calling the right one saves a transfer or two. Every number below comes from the company’s official contact, claims, roadside and billing pages:
- Customer service, quotes and My Account help: 1-800-726-6033 — 24/7, English and Spanish
- File or ask about an auto or property claim: 1-800-255-7828 (1-800-ALLSTATE)
- Roadside assistance: 1-800-347-8880 — 24/7, including weekends and holidays
- Life insurance claims: 1-800-366-3495
- Annuity claims: 1-877-499-6418
- Identity theft or fraud: 1-855-821-2331
- Automated bill payment by phone: 1-800-901-1732
- Corporate switchboard (SEC filings): (847) 402-2800
Customer Service and Support Channels
Phone is not the only way in, and for claims it is usually not the fastest. Allstate describes logging in to My Account as “the fastest way to file your claim,” and the same login lets you upload photos, track a claim’s status and view payments. The Allstate mobile app covers the same ground on a phone, plus ID cards, bill pay and roadside requests. Live chat is available 24/7 on allstate.com, with a separate Spanish-language chat, and there is a secure email form for anything that does not need an instant answer.
On social media, Allstate takes public questions through its verified @Allstate account on X, but you should never post a policy or claim number there. If you prefer a person, Allstate is one of the few insurers with a large physical footprint: more than 27,400 exclusive agents and licensed sales professionals work out of local agencies, and the agent locator on allstate.com finds the nearest one by ZIP code. One practical tip: because the main line is staffed around the clock, late evening and early morning calls avoid the daytime queues that build up after storms and major weather events.
Mailing Addresses for Claims and Payments
Sending paperwork to the corporate headquarters is the most common mistake — the Northbrook office does not accept customer mail at all. Allstate publishes two mailing addresses for customers, one for claims documents and one for overnight payments, on its claims help and billing and payments pages:
| Property and casualty claims mail | Allstate Insurance Company, PO Box 660636, Dallas, TX 75266 |
| Overnight (next-day) payments | Allstate Payments, 1501 N Plano Rd Suite 100, Richardson, TX 75081 |
| Regular payments | Pay online through My Account, the mobile app, Quick Pay, your bank’s bill pay, or by phone at 1-800-901-1732 |
| Corporate office (no customer mail) | The Allstate Corporation, 3100 Sanders Road, Northbrook, IL 60062 |
Phone-protection claims are handled separately by Allstate Protection Plans (formerly SquareTrade) through its own website, and flood claims use a dedicated flood loss report form rather than the general claims line.
Company Background
Allstate began life as a Sears side business. Sears, Roebuck and Co. launched Allstate Insurance Company on April 17, 1931, in the depths of the Great Depression, selling auto insurance by mail through the Sears catalog; the first policy covered a 1930 Studebaker for $41.60 a year. The first agent worked from a card table in the Sears booth at the 1933 Chicago World’s Fair, and agents soon spread through Sears department stores. The company’s official history traces the “You’re in Good Hands” slogan to the 1950s, the move to Northbrook to 1967, and the split from Sears to the 1990s: a 1993 initial public offering that was the largest in U.S. history at the time, followed by a full spin-off in 1995.
The modern company grew through acquisitions in protection services and personal lines. Allstate bought SquareTrade, the device protection-plan seller, for about $1.4 billion in January 2017 and has since rebranded it Allstate Protection Plans. In January 2021 it closed the $4 billion purchase of National General, which today anchors its independent-agent business alongside the Direct Auto brand. Going the other way, Allstate retired the Esurance brand in 2020 and folded those customers into the Allstate name. According to its 2025 annual report, Allstate is the third-largest personal property and casualty insurer in the United States, with roughly 53,000 full-time employees, 211 million policies in force, $67.7 billion in 2025 revenue and shares that trade on the New York Stock Exchange under the ticker ALL.
Leadership
Tom Wilson is Chair, President and Chief Executive Officer. He has been CEO since 2007 and Chair of the Board since 2008, making him one of the longest-serving chief executives among large U.S. insurers. The holding company, The Allstate Corporation, was incorporated in Delaware on November 5, 1992, ahead of the IPO, while its main operating subsidiary, Allstate Insurance Company, is an Illinois-domiciled insurer. Our Delaware business search guide and Illinois business search guide explain how to look up either entity’s registration.
Key Office Locations
Northbrook is the official home, but Allstate’s workforce is spread across roughly 645 retail stores, claims offices and support facilities in North America, and the company has kept office space in downtown Chicago even after abandoning the Wacker Drive headquarters idea. Its customer mail processing runs through the Dallas area in Texas, where both the claims post office box and the overnight payment center are located. Outside North America, Allstate owns a technology campus in Northern Ireland (Allstate NI) and leases offices in India, the United Kingdom and Australia. In Canada, Allstate sells through about 700 employee agents rather than the exclusive-agency model used in the United States.
Dealing with Customer Complaints
Start with the standard channels: call 1-800-726-6033 (or 1-800-255-7828 for an open claim), and keep a record of the date, the claim number and the representative’s name. If the front line cannot resolve it, ask for a supervisor or claims manager and then put the complaint in writing — through the secure email form on allstate.com, or by mail to Allstate Insurance Company, PO Box 660636, Dallas, TX 75266 for anything claim-related. Do not mail it to Northbrook; the corporate office does not receive customer correspondence.
Because insurance is regulated at the state level, your most powerful step is a complaint to your state’s Department of Insurance, which will open a file and require the insurer to respond in writing. Allstate’s lead insurer is domiciled in Illinois, and the Illinois Department of Insurance takes complaints online, by mail, or by phone at (312) 814-2420 in Chicago. If you live elsewhere, file with your own state’s regulator — the NAIC consumer portal links to every state insurance department and its complaint form. For unresolved disputes over the value of a claim, most Allstate auto and home policies include an appraisal clause that lets each side hire an appraiser; small-claims court remains an option of last resort.
Summary
Allstate’s headquarters sits at 3100 Sanders Road, Northbrook, IL 60062, the one building the company kept after selling its historic Northbrook campus — and it never did move downtown. Virtually everything a customer needs happens elsewhere: 1-800-726-6033 for 24/7 service, 1-800-255-7828 for claims, the Dallas post office box for claims mail, and your state Department of Insurance when escalation is needed.
