On Friday, 24,600 refugees from Ukraine arrived in Poland, according to the agency.
Meanwhile, a total of 3,409,000 people left Poland for Ukraine, including 25,400 on Friday, the Border Guard noted.
A deputy interior minister said in mid-June that Poland was home to some 1.5 million Ukrainians after many refugees from Russia's invasion of Ukraine decided to return to their country.
Poland in March passed a bill that offers wide-ranging support to Ukrainians escaping the Russian invasion of their country, which began on February 24.
The measure grants them residence rights and ensures access to education, healthcare and social benefits.
Nine in 10 Poles are in favour of accepting refugees from war-torn Ukraine, according to a survey.
Saturday is day 164 of the Russian invasion of Ukraine.
