Greece's EU-harmonised deflation rate was steady compared to February, showing prices fell by 1.9 percent in March.
Greek consumer prices fell by an average 1.3 percent in 2014 compared to a year earlier.
For years an inflation outlier in the euro zone, Greece has been in deflation mode for the last 25 months as cuts in wages and pensions and a deep recession exerted downward pressures.
Deflation in Greece hit its highest level in November 2013, with consumer prices registering a 2.9 percent year-on-year decline.
On an annual basis, consumer prices in the 19 countries sharing the euro fell 0.1 percent year-on-year in March.
The bottoming out of price declines is likely to be welcome news for the European Central Bank, which wants to keep inflation below, but close to 2 percent over the medium term.
It started printing money in March to inject more cash into the economy and ward off concerns of persistently falling prices, or deflation.
