# 2018 Copa Libertadores qualifying stages

The 2018 Copa Libertadores qualifying stages were played from 22 January to 22 February 2018. A total of 19 teams competed in the qualifying stages to decide four of the 32 places in the group stage of the 2018 Copa Libertadores.

## Draw

The draw for the qualifying stages was held on 20 December 2017, 20:00 PYST (UTC−3), at the CONMEBOL Convention Centre in Luque, Paraguay.
Teams were seeded by their CONMEBOL ranking of the Copa Libertadores (shown in parentheses), taking into account of the following three factors:
* Performance in the last 10 years, taking into account Copa Libertadores results in the period 2008–2017
* Historical coefficient, taking into account Copa Libertadores results in the period 1960–2007
* Local tournament champion, with bonus points awarded to domestic league champions of the last 10 years
For the first stage, the six teams were drawn into three ties (E1–E3), with the seeded teams hosting the second leg.
For the second stage, the 16 teams were drawn into eight ties (C1–C8), with the seeded teams hosting the second leg. Teams from the same association could not be drawn into the same tie, excluding the winners of the first stage, which were unseeded and whose identity was not known at the time of the draw, and could be drawn into the same tie with another team from the same association.

### Notes

* $^†$ The identity of the team Chile 4 was not known at the time of the draw, and was unseeded in the second stage draw.
For the third stage, no draw was made, and the eight teams were allocated into the following four ties (G1–G4), with the second stage winners with the higher CONMEBOL ranking hosting the second leg. As the identity of the winners of the second stage was not known at the time of the draw, they could be drawn into the same tie with another team from the same association.
* Second stage winner C1 vs. Second stage winner C8
* Second stage winner C2 vs. Second stage winner C7
* Second stage winner C3 vs. Second stage winner C6
* Second stage winner C4 vs. Second stage winner C5

## Format

In the qualifying stages, each tie was played on a home-and-away two-legged basis. If tied on aggregate, the away goals rule was used. If still tied, extra time was not played, and a penalty shoot-out was used to determine the winner (Regulations Article 29).

## Bracket

The qualifying stages were structured as follows:
* First stage (6 teams): The three winners of the first stage advanced to the second stage to join the 13 teams which were given byes to the second stage.
* Second stage (16 teams): The eight winners of the second stage advanced to the third stage.
* Third stage (8 teams): The four winners of the third stage advanced to the group stage to join the 28 direct entrants. The two best teams eliminated in the third stage entered the Copa Sudamericana second stage.
The bracket was decided based on the first stage draw and second stage draw, which were held on 20 December 2017.
