The two 20-year-olds have been held in custody in the South American country after 11kg of cocaine was found in their luggage in August.
Both women maintained that they knew the drugs - worth an estimated £1.5m - were in their bags, but that a gang forced them at gunpoint to carry the cocaine.
The pair, who have already served four months in custody, faced a maximum of 15 years in prison if the case went to trial and they were found guilty.
At the end of September McCollum and Reid decided to plead guilty in exchange for a lower sentence.
Although they received the expected tariff, there had been uncertainty over whether the judge would accept their plea bargain after prosecutors demanded a full confession.
The pair were sentenced by Judge Pedro Miguel Puente Bardales on Tuesday in what was described as a "brief process" in a Lima court.
"The women were very calm as the sentence was handed down at the court in the Sarita Colonia prison," judicial spokesman Daniel Vega explained.
So far they have been held at the notorious Virgen de Fatima prison in Lima but the spokesman said they would now begin serving their sentence in a Santa Monica prison.
He added: "It is still not clear whether they will be able to serve part of their sentence in the UK - the judge said that was not a decision for the court and they would have to reach an agreement with the prosecution."
