Achieve Unmatched Impressions With High-Profile Advertising in Mumbai
Mumbai is an enormous Indian city and the capital of Maharashtra state. It has a unique geography based on the Salsette Island peninsula, which is linked to the mainland by an extensive network of railways and roads.
With a population of more than 22 million, Mumbai is one of the biggest and most densely populated metropolitan areas internationally. Six million global visitors head to the city annually, making it the sixth most visited place on the planet.
The city's vibrancy, links with the Bollywood movie industry, and famous street food have made it a mecca for travellers. Its sheer size and diverse mixture of ethnicities mean brand advertisers can reach genuinely vast audiences with each strategically positioned campaign placement.
Why Advertise in Mumbai?
Across India, outdoor advertising hit a valuation of £997 million last year and is forecast to grow further to a market size of £1,650 million by 2033, with an annual growth rate of 5.8%.
Businesses are driving those investments by taking advantage of the greater transit advertising infrastructure, digital marketing opportunities, and the rapid ongoing urbanisation of this already impressive city.
Modern Mumbai is packed with programmatic displays and digital screens. With greater consumer mobility, advertisers are seeing that they can tap into advertising in a city that offers compelling cost-efficiencies and returns.
Mumbai's population density and thriving commercial ecosystem have also contributed to higher levels of affluence. The city is India's primary hub for entertainment and finance, which means brands can target investors, business owners, tourists, and niche demographics such as those engaged in specific sectors or industries.

Frequently Asked Questions.
-
Outdoor marketing in Mumbai is regulated by the Brihanmumbai Municipal Corporation. Rules cover all types of out-of-home displays, including digital and static billboards. They are primarily focused on safety, limiting the size of advertising displays, and ensuring public advertising structures are secure.
Billboards can be up to 40 by 40 feet, must be a maximum of 100 feet from the ground, and cannot be closer than 70 metres to the next large billboard or display or within 30 metres of a smaller billboard.
-
Mumbai is a sprawling city that has evolved into an international centre for business and trade. A number of well-known multinational corporations choose to base their headquarters here. The connections between international airports and highly skilled workforce particularly appeal to companies in finance, tech, and entertainment.
From an advertising perspective, this makes the city a great place to reach large and diverse audiences, a significant proportion of whom are engaged in these target sectors and who commute around the city on a daily basis.
