What to watch for
Italian numbers are mostly regular but the teen split (11-16 vs 17-19) and the vowel-dropping in compounds (ventuno not ventiuno, ventotto not ventiotto) create small traps. Phone numbers can be read either digit-by-digit or as groups of hundreds, and you never know which style someone will use. The varying grouping style means a single number might be read as "trecentoquarantasette" (347 as one word) or "tre-quattro-sette" (3-4-7).
Study tip
Master the teen split first: 11-16 end with -dici, but 17-19 start with dici-. Learn which vowels drop in compounds (before uno and otto). Practice recognizing numbers both digit-by-digit and as spoken groups, since Italians switch between styles freely. Italian numbers have a musical quality — the rhythm and melody of the language helps with memorization. Prices, train platform numbers, and addresses make great real-world practice.
