The Flag Code of India is a set of laws, practices and conventions that apply to the display of the national flag of India. Flag Code of India, 2002, has been divided into three parts. Part I of the code contains a general description of the national flag. Part II of the code pertains to the display of the national flag by members of public, private organisations, educational institutions, etc. Part III of the code pertains to the display of the national flag by union and state governments and their organisations and agencies. The Flag Code of India, 2002, took effect from 26 January 2002.

Earlier, the display of the national flag was governed by the provisions of Emblems and Names (Prevention of Improper Use) Act, 1950 (No. 12 of 1950) and the Prevention of Insults to National Honour Act, 1971 (No. 69 of 1971). The Flag Code of India, 2002, is an attempt to bring together all such laws, conventions, practices and instructions for the guidance and benefit of all concerned. Advocate B. M. Birajdar said, "The Flag Code of India 2002 permits unrestricted display of the tricolour, consistent with the honour and dignity of the flag,"

The Flag Code of India has been divided into three parts:-

The National flag of India is officially described in the Flag Code of India as follows: "The colour of the top panel shall be India saffron (Kesari) and that of the bottom panel shall be India green. The middle panel shall be white, bearing at its centre the design of Ashoka Chakra in navy blue colour with 24 equally spaced spokes." It was adopted in its present form during a meeting of the Constituent Assembly of India held on 22 July 1947, when it became the official flag of the Dominion of India. The flag was subsequently retained as that of the Republic of India. In India, the term "tricolour" (Hindi: तिरंगा, Tiraṅgā) almost always refers to the Indian national flag. The flag is based on the Swaraj flag, a flag of the Indian National Congress designed by Pingali Venkayya.

Khadi or hand-spun cloth was the only material allowed to be used for the flag but amendment to the Flag Code in year 2021 allowed the use of polyester and other machine-made fabric. Raw materials for khadi are restricted to cotton, silk and wool. There are two kinds of khadi used: The first is the khadi-bunting which makes up the body of the flag, and the second is the khadi-duck, which is a beige-coloured cloth that holds the flag to the pole. The khadi-duck is an unconventional type of weave that meshes three threads into a weave, compared to the two weaves used in conventional weaving. This type of weaving is extremely rare, and there are fewer than twenty weavers in India professing this skill. The guidelines also state that there should be exactly 150 threads per square centimetre, four threads per stitch, and one square foot should weigh exactly 205 grams (7.2 oz).

The Flag made of paper may be waved by public on occasions of important national, cultural and sports events. However, such paper Flags should not be discarded or thrown on the ground after the event. As far as possible, it should be disposed of in private consistent with the dignity of the Flag.

The rules regarding the correct methods to display the flag state that when two flags are fully spread out horizontally on a wall behind a podium, their hoists should be towards each other with the saffron stripes uppermost. If the flag is displayed on a short flagpole, this should be mounted at an angle to the wall with the flag draped tastefully from it. If two national flags are displayed on crossed staffs, the hoists must be towards each other and the flags must be fully spread out. The flag should never be used as a cloth to cover tables, lecterns, podiums or buildings, or be draped from railings. Whenever the flag is displayed indoors in halls at public meetings or gatherings of any kind, it should always be on the right (observers' left), as this is the position of authority. So when the flag is displayed next to a speaker in the hall or other meeting place, it must be placed on the speaker's right hand. When it is displayed elsewhere in the hall, it should be to the right of the audience. The flag should be displayed completely spread out with the saffron stripe on top. If hung vertically on the wall behind the podium, the saffron stripe should be to the left of the onlookers facing the flag with the hoist cord at the top.

The flag, when carried in a procession or parade or with another flag or flags, should be on the marching right or alone in the centre at the front. The flag may form a distinctive feature of the unveiling of a statue, monument, or plaque, but should never be used as the covering for the object. As a mark of respect to the flag, it should never be dipped to a person or thing, as opposed to regimental colours, organisational or institutional flags, which may be dipped as a mark of honour. During the ceremony of hoisting or lowering the flag, or when the flag is passing in a parade or in a review, all persons present should face the flag and stand at attention. Those present in uniform should render the appropriate salute.
