The latest jobless figure was in line with an earlier estimate by the labour ministry.
There were around 907,000 people without jobs nationwide at the end of September, down from 909,500 a month earlier, according to the state-run Statistics Poland (GUS) agency.
The statistics office reported earlier this week that employment in Polish companies dropped by 0.8 percent in September on average in year-on-year terms.
According to the European Union's Eurostat statistics agency, which uses a different methodology, unemployment in Poland had stood at 3.4 percent in August, marking one of the lowest rates in the 27-nation bloc.
