Inflation in the 19 countries sharing the euro currency remained stable in July, European statistics office Eurostat said on Thursday.
Core inflation metric excluding volatile energy costs and unprocessed food in the euro zone rose.
Eurostat confirmed its earlier flash estimate of annual inflation in the euro zone at 1.3 per cent, with price rises excluding energy and unprocessed food, a metric closely followed by the European Central Bank in setting monetary policy, also confirmed at 1.3 per cent.
While price rises are still below the ECB's target of close to but below 2.0 per cent per year, core inflation has increased from 1.2 per cent in June and came in above analyst estimates of 1.2 per cent in a poll of 29 economists conducted by Reuters.
Other economic data released on Thursday showed that the euro zone's trade surplus came in ahead of analysts' expectations at 26.6 billion euros (24.30 billion pounds) in June.
Eurostat added that exports from the euro zone increased by 3.9 per cent in June compared to last year, while imports were up 6.2 per cent.
In the first six months of the year, European Union trade rose with all its main partners, most notably with Russia, China and South Korea.
