The top two teams in each qualifying group will be guaranteed a spot in the draw for next summer's tournament in Germany.
Play-off spots will then be handed to twelve teams based on performances in the most recent edition of the UEFA Nations League. Those teams will be split up into three brackets of four, and the three teams that win their semi-final and final will head to the Euros.
With all of the cleared up, here's how things are looking...
Group A
Group A is one of the simpler groups, with Spain and Scotland securing the top two spots and their places in Germany last month.
Georgia are guaranteed a play-off spot as they finished top of their Nations League group, but Norway and Cyprus are out.
Group B
Having won every match thus far, France have secured top spot in Group B, and will be joined in Germany by the Netherlands.
The Dutch are guaranteed to finish ahead of Greece as they've beaten Gus Poyet's side twice, but the Greeks are at least guaranteed to make it into the play-offs.
The Republic of Ireland and Gibraltar are out.
Group C
England have already qualified for the Euros, but fellow giants Italy are in serious danger of failing to do so automatically for the second major tournament in a row.
Their final game is against Ukraine, and that clash will decide which of the two sides finishes second. The Azzurri can afford to draw the decider after beating North Macedonia, while the Ukrainians have to win.
Italy are at least guaranteed a play-off spot should things go wrong, while Ukraine are also likely to get one if they finish third.
North Macedonia and Malta are out.
Group D
Italy weren't the only major nation in trouble at the start of the international break, with Croatia far from certain of joining Turkey inside the top two of their group, but the World Cup semi-finalists are in a good position now.
That's because Wales failed to beat Armenia, being held to a 1-1 draw. As a result, all Croatia have to do to qualify is beat Armenia in their final match. Wales meanwhile have to beat Turkey and hope that the Armenians do them a favour. If that doesn't happen, the Welsh will go into the play-offs.
Armenia and Latvia are out.
Group E
Albania secured their place at Euro 2024 with a 1-1 draw against Moldova in their penultimate match, and the Moldovans are one of two sides that could claim second place in the group. but any one of three teams could get the second spot in the group. 's chances of qualifying automatically.
Moldova need to beat the Czech Republic to do so, while the Czechs only have to avoid defeat in the deciding clash, which will take place in Prague.
Both are guaranteed to finish above Poland, but the Poles are guaranteed a place in the play-offs. The Czechs are too, but Moldova can only qualify automatically.
The Faroe Islands are out.
Group F
Things are nice and simple in Group F, with Belgium and Austria guaranteed to finish in the top two spots and head to the Euros in June.
Sweden are the only one of the three other sides with no hope of making the play-offs, while Estonia are all but certain to do so. Azerbaijan will join them if Kazakhstan beat Slovenia.
Group G
Hungary can book their flights to Germany already, but Serbia still have some work to do before they can do so too.
They need to avoid defeat against Bulgaria or hope that Montenegro fail to claim victory against Hungary. Otherwise, the two nations that used to be one will trade places.
Lithuania and Bulgaria are out.
Group H
Denmark guaranteed their place in the next edition of the Euros with a 2-1 win over Slovenia, who still have their fate in their own hands.
To qualify, they must avoid defeat in their final match against Kazakhstan, who will secure qualification themselves with a win and go into the play-offs if they fail to claim victory.
Finland will go into the play-offs, while San Marino and Northern Ireland are out.
Group I
Group I is done and dusted, as Switzerland and Romania both did what they need to secure qualification in their penultimate matches.
Israel will go into the play-offs, but Kosovo, Belarus and Andorra are out.
Group J
Portugal have topped Group J with ease, winning every match, and Slovakia have already secured the second automatic qualification spot.
Luxembourg will go into the play-offs as will Bosnia & Herzegovina, and Iceland are highly likely to join them.
Liechtenstein are out.
