In the digital age, businesses can handle most interactions with customers online or over the phone. There are, however, some instances in which a business requests that customers send an inquiry by writing a letter. Typically, insurance companies make this request to ensure that they comply with a specific law or statute so that they will prevent legal problems in the future. If you're writing to an insurance company regarding a claim, confirmation of coverage or about some other issue, use the block format of a business letter to ensure effective communication. The block format for a business letter has one-inch margins, and all text is left-justified.

Write your full address at the top left of the letter, including your ZIP code, then skip one line and write the date.

Enter the name of the insurance company representative you spoke with on the phone or on the internet; and then enter the name and address of the insurance company. If you have the representative’s title, enter a comma after the person’s name and write the title, then skip a line.

Write a subject line for the letter. For instance, if your subject line is related to a claim, you could write the word 'Re' with a colon, followed by your claim number. Skip a line and write your insurance policy account number, then skip another line.

Open the main section of the letter with a salutation that includes the name of the insurance company’s representative, followed by a colon. Then, skip one line.

Write the purpose of your letter in the first paragraph. Use short, clear sentences, and get to the point as quickly as possible. For example, you could write: “This letter is regarding the injuries I suffered in a car accident on January 10, 2018. You asked me to send written confirmation that I wish to retain an attorney to file a civil claim against the person responsible.” Detail all of the conversations you've had with the insurance company’s representative, then skip one line.

In the second paragraph, describe any other relevant details that support the statement or description in the opening paragraph, and then skip one line.

In the third paragraph, state your desired outcome. For example, continuing with the same example as in step 5, you could write: “I am therefore asking that you confirm my right to file the civil suit with an attorney of my own choosing. My policy allows me this option, provided that I advise you of my intentions in writing.” Skip one line.

Conclude the letter by requesting a time period during which time you would like to receive a response, then skip one line.

Write the word “Sincerely” followed by a comma, then skip four lines and write your name. Sign your name in the space between the closing and your written name.
