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.
Portugal's Paulo Sousa was last month named as the new manager of the Polish national football team to replace Jerzy Brzęczek.
Sousa, 50, is a Portuguese soccer manager and a former professional player who played as a defensive midfielder. His credits as a coach include Leicester City, Italian side Fiorentina and France's Girondins Bordeaux.
Just two months before the start of World Cup qualifiers, he took over a Poland team captained by star striker Robert Lewandowski, FIFA's world player of the year for 2020.
Poland will next month begin its World Cup qualifying campaign with fixtures against Hungary, Andorra and England.
The Polish team will in June face Slovakia, Spain and Sweden in the group stage of this year's European championships, a tournament rescheduled from last year due to the coronavirus pandemic.
The head of the Polish Football Association (PZPN), Zbigniew Boniek, told a virtual press conference in January that the national team needed a new manager to put an end to "a sense of malaise" among players and ensure more quality ahead of the delayed Euro 2020 finals and qualifiers for the 2022 World Cup in Qatar.
The Polish team in 2019 celebrated advancing to the European tournament for the fourth time after a successful qualifying campaign.
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.
