Political, geographical, and climatic considerations were taken into account during the group allocation process to avoid certain match-ups. Political tensions meant Ukraine were not placed with Belarus, Kosovo could not be grouped with Serbia or Bosnia and Herzegovina, and Gibraltar was prohibited from playing Spain.
Additionally, extreme weather conditions are a factor. Only two of the following countries - Estonia, Finland, Latvia, Lithuania, Norway, the Faroe Islands, and Iceland - could be in the same group. The Faroe Islands and Iceland, being the most weather-sensitive, did not share a group. Geographical constraints also applied to Kazakhstan, Azerbaijan, and Iceland to minimise excessive travel distances during the qualifiers.
