Similarly, the names of the months June and July sound similar in German (Juni and Juli), both ending in an ee sound, so when talking over the phone (or radio) the latter is often pronounced with an aye sound instead.

German also has a "phonetic alphabet" (i.e. nouns and proper names used to spell out letters over the radio) similar to the NATO phonetic alphabet. There are actually multiple because they differ between Germany, Austria and Switzerland. Germany also has two separate standards (of course): https://de.wikipedia.org/wiki/Buchstabiertafel#Deutscher_Spr...

Most Germans know some of the postal alphabet (or an impromptu variation on it) because it's the older of the two. It's also worth mentioning that the postal alphabet was revised by the Nazis to eliminate "Jewish" (i.e. Biblical) names like Samuel, Zacharias and Nathan. Some of them were restored but that's how we ended up with Samuel/Siegfried, Zacharias/Zeppelin and Nathan/Nordpol. I'd say there's an 90% chance when spelling out a word or name over phone the other person will understand the postal alphabet and a 10% chance they'll be confused what you're doing.
