Eurozone inflation remained unchanged at 2.2 percent in December as initially estimated, final data released by Eurostat showed Wednesday.
The latest figure is the lowest since November 2010. Inflation has been hovering above the central bank's threshold limit of 2 percent for many months.
Monthly inflation, at the same time, came in at 0.4 percent, slightly above the consensus forecast of 0.3 percent.
Core inflation that excludes energy, food, alcohol and tobacco, edged up to 1.5 percent in December, in line with forecast, from 1.4 percent from November.
