The 2024 European Championship finals will be held in either Germany or Turkey, Uefa has confirmed.
The two countries were the only ones to submit a declaration of interest before the 3 March deadline.
Denmark, Norway, Sweden and Finland had considered a joint bid, but did not proceed.
Both football federations must now produce a full bid dossier by April 2018, with Uefa choosing the winner the following September.
"It's clear that there will be two strong bids for Uefa's showcase national team competition, and it will be a tough decision to make," said Uefa general secretary Theodore Theodoridis.
The tournament will return to a single-host format, after Euro 2020 will be held around 13 cities across Europe.
Turkey has never hosted a major tournament, while West Germany hosted the 1974 World Cup and 1988 European Championship and most recently the 2006 World Cup in a re-united Germany.
