The 2004–05 UEFA Cup qualifying rounds was the qualification competition that determined the teams participating in the main competition of the 2004–05 UEFA Cup.
In the qualifying rounds, UEFA divided the participating teams into three geographical regions: Northern, Central–East, and Southern–Mediterranean.
This meant that a club potentially seeded in an open draw format could be unseeded in the regional system, or vice versa.
The regional allocation of countries was generally as follows:[1] However, UEFA could make exceptions to these allocations to ensure an even number of teams in each region.
The team that scores more goals on aggregate over the two legs advance to the next round.
If the aggregate score is level, the away goals rule is applied, i.e. the team that scores more goals away from home over the two legs advances.
If no goals are scored during extra time, the tie is decided by penalty shoot-out.
Prior to the draws, UEFA forms "groups" in accordance with the principles set by the Club Competitions Committee, but they are purely for convenience of the draw and do not resemble any real groupings in the sense of the competition.
After the draws, the order of legs of a tie may be reversed by UEFA due to scheduling or venue conflicts.
The schedule was as follows (all draws are held at the UEFA headquarters in Nyon, Switzerland).
