India's rupee sign fuses the Devanagari letter ra with a Latin R
India's rupee symbol blends a Devanagari ra with a Latin capital R stripped of its upright stroke, topped by two parallel lines that nod to the tricolour flag and an equals sign. Designer D. Udaya Kumar's entry beat roughly 3,331 others in a national competition decided in 2010.
The government announced the contest on 5 March 2009, and Finance Minister Pranab Mukherjee asked for a sign that captured Indian ethos and culture. Five finalists made the shortlist. A decision due on 24 June 2010 was postponed at his request, and on 15 July 2010 ministers picked Kumar's design. Kumar, trained in architecture, was then a visual design student at the Industrial Design Centre at IIT Bombay, and later became an associate professor at IIT Guwahati.
Before then, the rupee was usually written Rs, an abbreviation shared with several other countries. What made the new sign usable everywhere was code: the Unicode Technical Committee accepted the position U+20B9 on 10 August 2010, and Unicode 6.0, released on 12 October 2010, included it. Ubuntu became the first operating system to support it by default that year, Microsoft issued a Windows update on 18 May 2011, and Apple added it with iOS 7 in 2013. Keyboards sold in India now carry it on the 4 key.
Physical money followed more slowly. Mukherjee's budget speech on 28 February 2011 promised the sign on coins, and on 8 July 2011 coins of 1, 2, 5 and 10 rupees bearing it entered circulation, while banknotes adopted it gradually. Postage stamps used it just once, on Commonwealth Games issues of 3 October 2010, and as of 2025 never again. A matching symbol proposed for the paisa was abandoned when those coins were withdrawn in 2011.
The contest itself was challenged. A participant, Rakesh Kumar, called the selection flawed; the Delhi High Court dismissed his petition on 26 November 2010, but in a later case in 2013 it told ministries to draw up transparent rules for design competitions, and the Finance Ministry issued guidelines on 11 April 2013. In the logo for Tamil Nadu's 2025-26 budget, the state swapped the national sign for a Tamil letter, drawing mixed political reactions.
