Things to remember...

  • You may only use a PO box for auto insurance billing statements and other documents
  • Auto insurance companies require a physical address when you apply for insurance rates 
  • You may manage your car insurance policy by mail 

There are plenty of legitimate reasons individuals use a PO box for mail. However, drivers must know insurance companies will not permit consumers to use a PO box for car insurance rates. A PO box address lacks the necessary information that a physical address provides.

Simply put, most auto insurance companies require knowledge of the official location of you and your vehicle in order to determine your rates. If you wish to use a PO box with an existing policy or a new coverage plan, you must understand how your physical address plays a role in your auto insurance coverage.

Can I use a PO box for car insurance?

The short answer is no. You may not use a post office box, otherwise known as a PO box, in place of a physical address when giving your insurance company your residential information. However, you may use a PO box address to receive mailed documents from your insurance company.

Why am I not permitted to use a PO box for car insurance coverage?

Auto insurance companies will use your residential address and ZIP code as factors to determine your auto insurance rates and statistics for litigation.

Your insurance company uses your home address and ZIP code to evaluate factors that may impact your auto insurance rates. For example, your ZIP code and address will let your insurance company calculate your daily commute to work and estimate driving miles. Additionally, your physical address provides information used in case of theft, car accidents, and other circumstances that involve auto insurance.

Since ZIP codes and home addresses have such an impact on your car insurance rates, you will need to update your information with your insurance company every time you change addresses. Unfortunately, using a PO box would save you time since a PO box address will not change. However, a PO box cannot provide the information necessary to determine your auto insurance rates.

Using a PO Box as a Mailing Address

While you cannot use a PO box as a permanent residential address, you may use your PO box as a mailing address. You can contact your insurance company and request that it send all written documentation to your PO box. Your insurance company should then mail billing statements, policy terms and requirements, proof of insurance cards, and any other statements or notices to your PO box address.

Insurance companies will also send digitally formatted documentation to an email address as an alternative to PO boxes and residential addresses.

Information Required for Auto Insurance Quotes

So what documents do you need to get car insurance? Insurance companies require certain info because insurance quotes and rates are unique to the driver. So, the best way to get an accurate car insurance quote is to provide accurate information about yourself, your vehicle, and your driving history.

Usually, most auto insurance companies require the same personal information and documentation in order to give you an accurate auto insurance quote.

What other information affects car insurance rates?

Your residential address is only one factor out of many that determine your car insurance rates. Other details typically required when you request a quote for new coverage include:

  • Your driving and claims history 
  • Demographics, like age and gender 
  • Your credit score
  • Information on your vehicle, such as a VIN
  • Your coverage types and limits
  • Your insurance deductible

You may need to provide additional information to qualify for discounts on your car insurance rates.

What if my rates are high and I cannot leave my residential address?

Generally, residential addresses and ZIP codes are outside of most drivers’ control. While you may not be able to change your address in order to get lower insurance rates, there are plenty of other ways to make up for costs outside of your control.

Shop for Lower Rates

Insurance rates vary considerably based on insurance companies and plans. Do your research before committing to any auto insurance policy. Researching a variety of car insurance companies and plans will create a basis for a financially feasible decision.

Request a Higher Deductible 

While applying for auto insurance coverage, your new insurance company will ask which deductible amount you prefer. Deductible averages may range from $500 to $1,000. A higher deductible will typically reduce your rates.

Before asking your providers for a higher deductible, review your finances to ensure that you can afford to pay the deductible if you need to file a claim on your car insurance policy.

Use Discounts

Most auto insurance companies offer policies with 6- to 12-month terms. The rate quote you receive covers the full cost of your policy in a term. Some auto insurance companies will grant a discount if you pay the full amount upfront.

Otherwise, most auto insurance companies also offer monthly or quarterly payment plans. With these plans, you may qualify for a discount depending on your insurance company.

There are also plenty of other discounts that some insurance companies offer despite your residential address. Typical discounts that you may find through your auto insurance company include:

  • A bundle discount with your auto, home, and life insurance policies
  • A discount for insuring multiple drivers or vehicles under the same policy
  • A good student discount for making excellent grades
  • A safe driver discount
  • A low mileage discount

You will need to check with your insurer for specifics on how to qualify for discounts.

Understanding Why You Can’t Use a PO Box for Car Insurance Rates

However convenient it may be, your insurance company will not accept a PO box for car insurance rates. Insurance companies require a physical address to determine your auto insurance rates. Still, most car insurance companies will permit drivers to use a PO box as a mailing address only. If you are concerned about high auto insurance costs and are unable to move your physical address, simply look into other ways you may be able to lower your rates.
