What are the Different Types of Letter?

We will learn here the types of letters. We already got the basics of letter writing in our earlier article. Letters are broadly divided into two types;

  • a formal letter and
  • an informal letter.

As discussed in the previous post, both these types will have their specific approach.

In this post, we will be looking at a few examples of both these types of letters. Now, let’s talk about them one by one. First, let’s talk about formal letters.

Types of Letters – Formal & Informal Letters

We have already learned how to write a letter. Now, here, we will explore what are the main types of letters. Basically, there are two types of letters,

  • Formal letters
  • Informal letters

Let’s learn both types of letters in brief,

Formal Letter Types

Needless to say, that when you are writing a formal letter, the tone of the letter should always carry a formal tone. This very fact should govern your approach to writing the rest of the letter. Like, in a formal letter, you need to restrain yourself from using any casual words, phrases, or even an idea.

  • Most of the time, the formal letter you are writing will be addressed to some authority.
  • It can be to the chairperson of an educational institution, it can be to a political figure, or it can be to the HR of any company.

Since the relationship you have with all of these recipients is not informal, the letter should carry that vibe as well. You need to be very concise and to-the-point with the content and use selective words to convey your opinion. Also, you should always maintain the formality and politeness of the letter and avoid using any personal connotations. Formal letters can be various types, like

  • Business Letter
  • Official Letter
  • Social Letter
  • Report Letter
  • Notice Letter
  • Circular Letter
  • Order Letter
  • Complaint Letter
  • Employment Letter

On the other hand, you have informal letters.

Informal Letter Types

This type is the most frequently used one, although nowadays, we write formal letters more than informal ones. The idea behind writing this letter is quite simple. Most of the time, we use these letters to convey our experiences with our friends, relatives, and even our loved ones.

  • There are no hard and fast rules regarding the language of the letter.
  • You can be absolutely frank and casual with your letter.
  • Since you are writing to someone you already know, you don’t have to maintain a formal tone but can easily write your heart out.

For both types, make sure to correctly put the date and address; otherwise, the letter will not reach the desired recipient.

Formal Letter Examples to Friend

Write a letter to your friend to tell him about your recent vacation

1254 Street, West Avenue


Pin: 5468799

Dear Atul,

It’s been a long time since I have written to you. How are you? I hope this letter finds you in good health.

As you know, I have always loved traveling, and during every summer vacation, my legs itch badly for going somewhere. So, this summer vacation was no exception either.

You know Atul, sometimes; I can hear the mountains calling me in my dream. So, I again visited the mountains, a small town called Rishop, situated in Sikkim. You won’t believe it, but this little town has breath-taking natural splendor. We were fortunate because, on the second day of our trip, we managed to see the magnificent Kanchanjangha. I have witnessed this grand mountain range before as well, but every time I see visit the mountains, it never fails to amaze me time and time again.

Have you visited the mountains lately? Well, even if you have, no worries. Next year, we will go together during the summer vacation, and I won’t listen to any of your excuses, okay?

No more for now. Please give my best regards to your parents and take care of yourself.

Yours truly,

Dear Mom,

I hope this letter finds you in good health. However, I am very much sure that you are sick worried about me. Please stop worrying, dear mother; I am doing absolutely fine and have already settled here. The food habit of people around here is a bit different than ours but fret not; I can manage, your son is no longer a young child.

Please don’t always cry in front of Baba’s picture. You know how Arun hates it. Your younger son is also quite capable of taking care of his mother, and he is always in touch with me, and I am always there to guide him. Father is always with me as well, dwelling inside my heart and his blessing always protecting me.

I know you are missing me, and I am missing you all as well. But don’t let that hamper your health. Otherwise, I will not be able to concentrate on my work here. As of now, everything is fine, and I will take care of myself as you have said.

You will always receive a letter from me, every week, I promise!

Please take care of yourself. I love you!

Yours always,

Respected Madam,

I am writing this letter to convey my decision to resign from my post of Junior Analyst in your company.

I wish to resign from my responsibilities within one week of the current date. A few days ago, I received my confirmation of selection in JGG Technologies as a senior analyst. I have decided to take this opportunity as it will be very much beneficial for my future.

I am greatly indebted to this company, and I can never forget the kind of cooperation I have received so far from all my seniors and other authority members, including you.

However, my professional tenure with this company has come to an end.

Therefore, please accept my resignation and do the needful. Also, please let me if I need to present any other document or not.

It was a pleasure working with you.

Looking forward to hearing from you soon.

Thanking you,

Yours sincerely,

Alokesh Maity

The Bank Manager

Janta Private Bank

East Range,


Pin – 12365

Sub: Change of Address and Account Transfer

Respect Sir,

I am writing this letter to draw your kind attention to a very important matter regarding my account with your bank. I have been a savings account (A/c no. 7896541236454789) holder of your bank for the past seven years, and during this time, I have been living in 7th Avenue, Gurgaon, in a rented apartment quite near to this branch.

However, my son has recently bought a new property in the East Range, 9th Street, and I will be shifting there permanently within a week from today.

Therefore, I request you to kindly update the new address I have mentioned in your system and also transfer my account to the 7th avenue branch since it will be nearer to my new residence. As you can see, it will be pretty difficult for me to come all the way down here to perform my banking operations.

Would you mind letting me know if you require any further documents from my end?

Looking forward to hearing from you soon.

Thanking you,

Yours sincerely,

Arun Gupta

Write a letter to the school principal for new books in the library

Respect Sir,

I am a student from Eight-Standard of your school, and I am writing this letter on behalf of all my classmates to draw your kind attention to a critical matter.

In our class, we have just started to learn about Biology, Chemistry, and Physics. But for reference study, adequate amounts of books are not there in the library. These books cost a lot, so if we could avail them from the school library, it would be very helpful.

Also, along with these reference guide books, if we could get some foreign storybooks, it would be even better.

Therefore, I request you to kindly accept our request and do the needful at your earliest convenience.

Thanking you,

Yours sincerely,

Manish Gupta
