Spelling your name or email address over the phone is a near-universal need - and German letter names don't match English ones. Worth memorizing outright rather than improvising in the moment.
| A | ah | J | yot | S | ess |
| E | eh | K | kah | V | fau |
| G | geh | Q | kuh | W | veh |
| I | ee | R | err | Y | üpsilon |
The biggest trap: E sounds like English "A," and I sounds like English "E" - reversed from what an English speaker expects.
| Ä | ah-Umlaut |
| Ö | oh-Umlaut |
| Ü | uh-Umlaut |
| ß | Eszett / scharfes S |
Like English "A for Apple," German has an official spelling alphabet for when clarity really matters (phone calls, dictating official documents):
| A | Anton |
| B | Berta |
| M | Martha |
| N | Nordpol |
| S | Samuel |
Full list available from Deutsche Telekom or the DIN 5009 standard if you need it for a specific call - the pattern (a common first name or word per letter) is the same idea as NATO's "Alpha, Bravo, Charlie."
