Vyacheslav Malyk of Delta Junction pleaded guilty in December to second-degree felony theft.
He will be released from custody after spending the past 11 months in jail and at a halfway house.
Malyk is among eight people who were accused of stealing hundreds of mail items from neighborhoods outside of the city limits in 2008.
Seven of them have pleaded guilty and one case is pending.
Authorities say Malyk altered a $1,400 check to include his actual home address, then cashed the check at Walmart.
At the sentencing hearing, state Superior Court Judge Robert Downes told Malyk he was a "lousy criminal."
