Belgium, who finished third in the 2018 World Cup in Russia, remain at the top of the FIFA rankings, ahead of world champions France.
Brazil are at No. 3, ahead of England in fourth spot.
The global football governing body said its latest World Ranking remained unchanged from the previous edition amid the coronavirus pandemic.
“Although club football has slowly restarted or been scheduled to restart in various leagues around the world, the spread of COVID-19 remains an obstacle to the staging of international matches,” FIFA said on its website.
Jerzy Brzęczek last month agreed a contract extension to manage the Polish national football team until at least the end of next year.
The extension came after this year’s European championships were postponed until 2021.
The Polish team last year celebrated advancing to the European tournament for the fourth time after a successful qualifying campaign.
Brzęczek, a former Poland captain, took over as Poland manager to replace Adam Nawałka in the summer of 2018 after the national squad's early World Cup exit disappointed fans.
Poland in 2017 had climbed to No. 5 in the FIFA table, the best result for the Polish team since the world football governing body’s ranking was launched in 1992.
Poland's lowest place in the world rankings was 78th, in 2013.
