Russian President Vladimir Putin has ordered 160,000 servicemen be drafted by 15 July, a higher figure than previous conscription drives as Moscow seeks to boost its army's size.
Russian men are eligible to be drafted for mandatory military service through bi-annual call-ups.
The Kremlin and defence ministry say they are not sent into combat and the call-ups have nothing to do with the Ukraine conflict.
However, Ukraine has said throughout the conflict that it has taken Russian conscripts captive and Mr Putin admitted at the start that some had been sent to fight by mistake.
Yesterday Mr Putin outlined the plans for this year's spring conscription in a decree.
The planned draft size was up to 160,000, from 150,000 in 2024 and 134,500 in 2022, when Russia launched its offensive on Ukraine, state media reported.
Last year Mr Putin ordered Russia to boost the size of its army to 1.5 million active servicemen - an increase of some 180,000 troops over three years.
"The forthcoming draft campaign is in no way connected with the special military operation in Ukraine," the defence ministry said on social media.
Apart from its conscription drives, Russia has recruited hundreds of thousands of men for its offensive on Ukraine as paid contract soldiers, offering high salaries and massive sign-up bonuses.
Russia traditionally holds waves of conscription in spring and autumn, with men aged 18-30 eligible to be called up.
Mr Putin raised the upper age limit from 27 in 2023.
The spring call-ups will run from 1 April until 15 July, according to Mr Putin's decree.
Despite pledging that conscripts do not get sent to the front, Russia drafted more than 300,000 "reservists" in 2022 for its Ukraine offensive in what it called a "partial mobilisation."
That triggered hundreds of thousands of men to flee the country to avoid being called up.
