How To Write A Formal Letter? Types, Samples And Tips 

Writing a formal letter is an essential skill that can be useful in various situations, such as applying for a job, filing a complaint, making an official request or communicating professionally in business or academia. Whether you are addressing a company, a government official or a prospective employer, a well-structured formal letter helps to establish credibility and professionalism. A carefully written formal letter ensures that your message is taken seriously and receives the appropriate response.

In today’s world, where emails and digital communication are dominating, formal letter writing still holds great importance. Many organizations require physical or well-formatted digital letters for official purposes, legal documentation and professional interactions. 

In this guide, we will explore how to write a formal letter, its types, format, samples and some useful tips.

What Is A Formal Letter?

A formal letter is a professionally written document used for official communication. Unlike informal letters, which are written to friends or family, formal letters are used in business, academic or government related work/contexts.

There is still a belief that formal letters are meant to be handwritten with stamps and a signature, however the scenario has changed with modern times. Now, formal letters are sent through emails but the goal still remains the same – to communicate messages clearly and professionally.

Types Of Formal Letters

Formal letters are classified into different types based on their purpose. Here are some common types:

1. Business Letters

A business letter is a formal way to communicate professionally between individuals or organizations. It can be about business deals, orders or any work-related discussion. 

Example: A company writes to a supplier/merchant to order products.

2. Job Application Letters

A job application letter is written when someone wants to apply for a job. It has information about the person applying for the job role, their key skills and explanation to why they are a good fit for the job. This letter is sent along with a resume.

A complaint letter is written to express dissatisfaction/unhappiness with product/service provided by any company. This letter is aimed to resolve the problem (If any) and in some cases seeking a refund or replacing the product.

Example: A customer writes to a shop about a broken phone they received.

4. Inquiry Letters

An inquiry letter is written to ask for information about a product/service/course. These letters are sent to businesses, schools or offices.

Example: A student writes to a college asking about admission fees and course details.

5. Resignation Letters

A resignation letter is a formal way for an employee to inform their organization about their decision to leave the job. It serves as an official record for both parties, outlining the notice period and remaining working days within the company.

6. Invitation Letters

An invitation letter is written to formally invite and request guests to be a part of an event, such as a meeting, seminar or wedding function. It includes the date, time and venue of the occasion.

Example: A company invites its employees to a yearly business meeting.

7. Official Request Letters

An official request letter is written to ask for permission or approval. It is usually sent to a school, office or government department.

Example: An employee requesting for work-from-home through a formal letter.
