Unemployment in the 16-member euro zone remained at a record 10% in May for the third month running.
Almost 16m people were out of work as the unemployment rate in the crisis-hit zone remained at its highest level since the euro's creation in 1999, seasonally-adjusted Eurostat figures showed.
The official statistics agency had initially estimated an unemployment rate of 10.1% for April, but it revised the figure down to 10%.
The unemployment rate in the wider, 27-nation European Union stood at 9.6% in May, also unchanged from the previous month, for a total of 23.13m people without jobs.
Among the eurozone's biggest economies, unemployment fell slightly in Germany to 7.0% in May from 7.1% the previous month. It stood still in France at 9.9% and in Italy at 8.7%.
In Spain, the unemployment rate rose to 19.9% compared to 19.7% in April.
