The official letter is a type of document that is made to deliver an official communication to a particular recipient and that can be issued by both private and public entities.

In the same way, the usual thing is that the size of the paper is letter (21.59cms x 27.94cms), although this does not mean that you cannot choose the legal format (21.59cms x 35.56cms) or A4 (21cms). x 29.7 cm).

According to this, an official letter is written with the purpose of communicating or notifying, but based on a strictly formal writing or writing.

In other words, knowing this will make it easier to understand that the answer to how to write an official letter refers mainly to fulfilling the conditions determined in the formality of writing the document.

Types of trade

To learn how to write an official letter, it is essential to know this kind of categorization system, since this way it will be much easier to form a relationship between the organization from which the document is issued and the recipient.

Trades by origin and institutional destination

inner office

It results when the office is for internal use, being mobilized within any government office. In the corporate case, it is mobilized only within the company. Under this aspect, the trades can be called

Local interior office: if the issuance and destination of the office is in the same building or institution. It does not leave the premises.
Foreign internal office: when the office is transferred to other institutions or government buildings.

foreign office

This type corresponds to official documents issued by agencies for private entities outside the government or for the general public. In the case of companies, it is when it is issued to anyone who is not from the same company or branch.

Trades that are intended for one or more people

Simple or direct office

The simple trade or also called direct trade is the one that makes a statement that is addressed to a single institution or person in particular, this being generally called the owner.

If it is issued by a government institution, it has official validity, and if it is issued by a business institution, it will then have business validity.

Certain trades are officially valid, even if they are not issued by government institutions, such as trades issued by credit institutions or banks, or school trades from private schools, among others.

Multiple trade

This job has the same structure as a simple job. However, it is addressed to several people at the same time, which makes its wording more universal, so that it is understandable by everyone and not by someone specific.

What information should an official letter include?

Place and date

The official letter begins with the inclusion of this information, so that the date and place of issuance of the document is clear.


It consists of showing the data that will allow this document to be identified through, for example, the initials of the office that elaborates it, the issue number and the current year. Depending on the institution, this may vary.


It is given as a suggestion that the full name of the person, his position and the place of destination be included. It is best that this does not occupy more than four lines in the document.


You can optionally specify the subject on which the document deals, followed by a summary of it, with which a brief explanation of the content of the official letter is given.


When talking about how to write an official letter, it must be clear that this part turns out to be the key point of the official letter, since it is where the message is made known.


You must remember to say goodbye in a friendly way, so that the relationship can be maintained on good terms. Do not forget to write a «Sincerely» at the end, with the name and signature of the issuer.

In addition, the best thing to do is to be able to stamp the official letter with the organization’s logo, since it gives the document greater validity.
