The stamp that shows a photo of a traditional 'diya' lit against a sparkling gold background and the words 'Forever USA 2016' written below will be formally unveiled on October 5.
The postage stamp will be issued by the US Postal Service (USPS) from November "honouring Diwali, the festival of lights," Congresswoman Carolyn Maloney from New York said.
USPS Sally Andersen-Bruce of Connecticut photographed the diya and Greg Breeding of Virginia designed the stamp, with William Gicker of Washington serving as the project's art director.
She lamented that despite Diwali being an "important spiritual and cultural festival" for many Indian-Americans and millions around the world, it had not been given its own commemorative stamp till now. Given that every other major religion has its own commemorative stamp, she said a stamp for Diwali had been long over-due.

She was joined by India's Consul General in the city Riva Ganguly Das, Chair of the Diwali Stamp Project Ranju Batra and eminent Indian-American attorney Ravi Batra as she made the "historic" announcement from the steps of the City Hall.
The efforts in the Indian-American community had been spearheaded by Ranju Batra, who as chair of the Diwali stamp project and with the help of other community leaders, got tens of thousands of signatures for petitions to issue the stamp.
Maloney had also informed Prime Minister Narendra Modi, during his visits to the US in 2014 and 2015, about efforts to get a Diwali postage stamp issued, Batra said.
Ravi Batra called the move as the "strongest soft power that combines a billion people of India" as he lauded Maloney for her years-long efforts.
"An important recognition for the more than 3 million Indian-Americans who celebrate Diwali," tweeted Senator Mark Warner, Co-Chair of the Senate India Caucus.
Congresswoman Tulsi Gabbard, the only Hindu member of Congress, led the most recent write in campaign to the USPS with hundreds of signatories.
"This has been a long and arduous process but this act by the USPS to recognize this special day and to further increase and enrich our nation's tapestry of religious and cultural diversity will be greatly appreciated by many," Gabbard said.
Ami Bera, the only Indian-American lawmaker in the US Congress, also welcomed the decision.
"I'm thrilled that the United States Postal Service has issued a stamp to celebrate Diwali," Bera said in a statement.
Bera, Co-Chair of the Congressional India Caucus, had pushed for a stamp since he came to Congress in 2013, leading the effort by co-sponsoring several resolutions.
"Diwali is a celebration of goodness over evil observed by nearly a billion people around the world, including more than two million right here in the US. This stamp is long overdue, and I'm glad Diwali has the same acknowledgment as many other major religious holidays do with a commemorative stamp," he said.
