　　When saying or writing out numbers, the British put an and before the tens and units (个位数), as in one hundred and sixty­two or two thousand and three. In the United States it is considered correct to drop the and, as in one hundred sixty­two or two thousand three.

　　In counting, it is common in both varieties of English to count in hundreds up to 1,900 - so 1,200 may be twelve hundred. However, Americans use this pattern for much higher numbers than is the norm in British English, referring to twenty­four hundred where British English would most often use two thousand four hundred.

　　In the case of years, however, twelve thirty­four would be the norm on both sides of the Atlantic for the year 1234. The year 2000 and years beyond it are read as two thousand, two thousand (and) one by both British and American speakers. For years after 2009, twenty ten, twenty twelve etc. are becoming common.

　　For the house number (or bus number, etc.) 272, British people tend to say two seven two while Americans tend to say two seventy­two.

When referring to the numeral (数字) 0, British people would normally use nought, oh, or zero, although nil is common in sports scores. Americans use the term zero most frequently; oh is also often used. When a phone or account number is being read aloud, 0 is nearly always pronounced oh in both language varieties for convenience.
