The figure was in line with an earlier estimate by the country’s labour ministry.
There were around 865,500 people without jobs at the end of August, down from 868,400 a month earlier, according to the Central Statistical Office.
Poland's Labour and Social Policy Minister Bożena Borys-Szopa told reporters last month that the 5.2 percent jobless figure for July marked the lowest unemployment rate in the country for that month since 1991.
Poland's unemployment rate is expected to fall to 5.1 percent at the end of 2020 under a set of budget targets adopted by the country's government earlier this year.
