Joachim Low's Germany – who finished third at the 2010 World Cup in South Africa – booked their place in Brazil with a classy 3-0 triumph over the Republic of Ireland in Cologne.
Sami Khedira's deflected strike put Germany in front after just 12 minutes before second-half goals from Andre Schurrle and Mesut Ozil capped off the victory to see them progress as the winners of Group C, giving them their eighth win in nine qualifiers.
Meanwhile, Romelu Lukaku scored twice as Belgium defeated Croatia 2-1 in Zagreb to confirm their position at the top of Group A.
The Everton forward struck in the 15th and 38th minutes and despite Niko Kranjcar coming off the bench to pull one back with six minutes to play, Marc Wilmots' men held on for all three points.
Switzerland were the other side to secure their qualification after a 2-1 win away to Albania in Group E.
After a goalless first half, Xherdan Shaqiri's 48th-minute effort set Switzerland on their way before Michael Lang doubled their advantage with 13 minutes left.
Hamdi Salihi scored a late effort from the penalty spot but it was in vain as Switzerland extended their unbeaten record to 13 matches in all competitions.
