Cultural Tip
In German‑speaking countries it is common to ask for the name with ‘auf’ or ‘unter’ in service situations. ‘Auf welchen Namen?’ sounds slightly more formal than the everyday ‘Wie heißt es?’, and it is preferred when dealing with paperwork or official records. Remember to keep a polite tone – adding ‘Bitte’ after the answer is customary.
