What Information Do You Need to Compare Auto and Home Insurance Quotes?
By Insurazon Editorial Team | Published 2026-09-30
A practical checklist of policy, driver, vehicle and home information, plus a worksheet for comparing written insurance quotes.
Start with one consistent set of information
To compare auto or home insurance quotes, gather your current policy declarations page, the details of the people or property being insured, recent claims information, and the coverage limits and deductibles you want each insurer to quote. Ask for the same effective date and policy term. Requirements differ by insurer, product, and state, so this is a preparation checklist rather than a universal application form.
Keep one dated comparison folder. Save the information you supplied, each written quote, and the questions still unanswered. When a detail changes, tell every insurer you are comparing so you are not choosing between prices based on different assumptions.
This guide focuses on personal auto and homeowners insurance. Health, Medicare, life, renters, and condo products have different questions and documents. A licensed professional can explain what is required for your situation.
Find your declarations page first
Your declarations page is a useful starting point because it summarizes who or what is insured, policy dates, limits, and deductibles. The NAIC explains the role of this page in its auto insurance consumer guide. It is a summary, so keep the full policy and endorsements available for questions about exclusions or conditions.
Make a note of your renewal date and any changes since the policy began. Examples include a new driver, a different commuting pattern, a roof replacement, or a home renovation. Ask an insurer to explain any estimate based on old information before you rely on it.
You do not need to understand every insurance abbreviation before shopping. Flag unclear items and ask the agent to translate them into a plain-language description. Copying an existing limit without understanding it can preserve a gap you hoped to fix.
What to have ready for an auto insurance quote
Prepare a list of the drivers and vehicles you want considered. Have accurate names, dates of birth, vehicle year, make, model, and vehicle identification number available for an insurer that requests them. Note where the vehicles are kept, their usual use, and estimated annual mileage. The NAIC auto shopping tool includes driver, vehicle, mileage, and existing coverage questions.
Record relevant accidents, violations, and claims as accurately as you can. If you are unsure of a date or detail, say so and ask how to verify it. Guessing to finish a form can make the comparison less useful when the insurer reviews the application.
Write down the coverages you want included, such as liability and any collision or comprehensive coverage. Ask which additional coverages and limits apply in your state. If the vehicle is financed or leased, have the lender's or lessor's insurance requirements ready rather than assuming the cheapest option will satisfy them.
Before comparing totals, ask whether the quotes use the same drivers, vehicles, mileage, limits, and deductibles. Keep optional benefits such as rental reimbursement or roadside assistance on their own line. That makes a difference in the package visible instead of hiding it inside the price.
What to have ready for a homeowners insurance quote
Gather the property address, approximate square footage, year built, construction type, and information about the roof and major updates. Note how the property is occupied and tell the insurer about uses such as renting it out or operating a business there. The NAIC home insurance guide explains that property characteristics, protection features, and claims history may affect a quote.
Have your current dwelling limit and deductible handy, but ask how the insurer calculated the proposed rebuilding amount. The NAIC distinguishes replacement cost from market value. A home's sale price and mortgage balance are not a substitute for checking the proposed rebuilding estimate.
List belongings that may need special discussion, such as jewelry, art, or business equipment. A simple room-by-room inventory helps you ask more specific questions about personal property limits. You can start with a short list and improve it later rather than leaving the issue out of the conversation.
Ask about deductibles for different events, how losses are valued, and important exclusions. The NAIC notes that some catastrophe deductibles are percentages. If a quoted deductible is a percentage, ask what amount it applies to and have the insurer show the dollar calculation. Ask separately about flood or earthquake coverage where relevant.
Use a comparison worksheet before choosing a price
Put each quote in a separate column and fill in the rows below. Mark an unanswered item as unknown. Do not silently treat a missing benefit as included or an unexplained discount as permanent.
California's Department of Insurance recommends getting auto quotes in writing and reviewing coverage, price, and service. Its guide is California-specific; use your own state insurance department for local requirements. Asking for a written explanation of differences is a useful way to make your comparison reviewable.

A lower monthly payment can hide a different comparison
Illustrative example: one auto quote shows a six-month term and another shows an annual term. One includes collision coverage and the other does not. Their monthly payment amounts do not tell you which package better fits your needs. First align the term and coverage, then ask for a breakdown of the payment schedule and any fees.
A similar issue appears when one home quote uses a percentage deductible and another uses a fixed dollar amount. Record the dollar exposure each insurer explains for the event being discussed. This example is a comparison method, not a recommendation for a particular deductible or an estimate of what you will pay.
If you want to explore a different coverage level, ask each insurer for a separately labeled alternative. Keep your baseline quotes together and your alternatives together. That small organizational step keeps a useful price experiment from turning into a confusing pile of unrelated numbers.
Share sensitive details through the right channel
Preparing information does not mean sending every document to every website. Check who is asking, why they need it, how they will use it, and whether you are speaking with an insurer, licensed agent, or a matching service. Use the state insurance department to verify licensing when relevant.
Keep driver's license numbers, Social Security numbers, payment details, and full policy documents out of open messages or a general notes box. If a verified insurer needs sensitive information, ask for its secure process. The right information and timing depend on the actual recipient and stage of the request.
Insurazon's matching request is an intake for review. It is not a live quote comparison or a policy application. The current form says no provider is selected or automatically sent the request. Follow the fields and consent text shown in the form, and do not add sensitive identifiers to optional notes.
Questions to ask before you rely on a quote
Ask: Is this a preliminary estimate or a price based on completed verification? What information could change it? Which coverages or endorsements are excluded? When would coverage start, and what document confirms it? Request a written response to anything that affects your decision.
Do not assume submitting a request starts coverage. Before changing an existing policy, confirm the new policy's effective date and any requirements with the issuing insurer or licensed professional. Keep the confirmation with your comparison records.
Your next step is practical: find your declarations page, fill in the worksheet for two or more quotes, and send the same unanswered questions to each contact.
