The ATP Rankings determine a player’s standing among the world’s best players and are used for tournament entry and seedings. They traditionally operate on a "Best 18" results basis over 52 weeks, but were frozen in March due to the coronavirus pandemic.

The newly revised ranking system will now cover a period of 22 months (March 2019 – December 2020), with the aim of delivering the following objectives:

• Provide flexibility & fairness to players across all levels in parallel with the condensed number of points available as part of the revised provisional 2020 calendar.
• Provide stability for players who cannot or prefer not to compete in 2020 due to health & safety.
• Provide a system that can adapt to further changes in the calendar if necessary.
• Reward players who perform well following the resumption of the Tour in 2020.
• Retain the principle of defending tournament points week by week in 2021, maintaining player mobility in the rankings.

Since the rankings will be comprised of a player's "Best 18" results between March 2019 and December 2020, he cannot count the same Tour-level tournament twice. Furthermore, Tour-level tournament points added in 2020 that count in a player’s Ranking Breakdown will remain on a player’s ranking for 52 weeks, or until the event in question is played again in 2021, whichever comes first.

The revised FedEx ATP Rankings will determine the singles qualifiers to the 2020 Nitto ATP Finals. As per normal, points earned at the season finale (as an additional 19th event) in 2019 will not count towards a player’s qualification for the 2020 event, ensuring a level playing field for 2020 qualification.

In doubles, the 2020 FedEx ATP Doubles Team Rankings will continue to be used to determine the eight teams that make it to London.

The temporary changes to the Rankings system have been made in consultation with the four Grand Slam tournaments and the ITF. Should the 2021 season be impacted by Covid-19, further adjustments to Rankings will be considered.
