Sukhoi's civil aircraft division has identified 12 customers comprising the 168 orders for its Superjet 100 aircraft.
The airframer had listed the order total in a newly-released update on its activities up to the end of the fourth quarter of 2011.
Sukhoi said there are 113 orders attributable to its domestic and Asian market, and a further 55 obtained by its marketing venture Superjet International, which specialises in Western sales.
On Sukhoi's side, Russian flag-carrier Aeroflot and Indonesia's Kartika Airlines are each taking 30, while 24 others are destined for Vnesheconombank's leasing arm which is planning to place them with UTAir.
Indonesian start-up Sky Aviation is to have 12 while another start-up, Lao Central Airlines - formerly known as Phongsavanh - is taking three.
Russian energy transport firm Gazpromavia will have 10, Yakutia is to take two through lessor FLC, and Armavia has also ordered two - one of which was the first Superjet delivered, nearly a year ago.
Sukhoi also listed Superjet International's backlog as comprising 15 for Mexico's Interjet, four for Italian carrier Blue Panorama - an airline which is to merge with Alitalia - plus six for US-based Willis Lease Finance, and 30 for lessor Pearl Aircraft Corporation.
Several other operators have signed tentative agreements to take Superjets, including Kuban Airlines, Moskovia Airlines, Yamal and Tajik Air.
Sukhoi has also unveiled a corporate version which has attracted interest from Indian company Aviotech and Switzerland's Comlux.
Only Aeroflot and Armavia operate the Superjet. Armavia has a single aircraft while Aeroflot took delivery of its fifth in January.
