番 number

I'd like to BAN the number 13 because it is unlucky.

I'll come to your rice paddy if you write down the address NUMBER.

number ★★★★★
番 (number) + 号 (ID number) = 番号 (number)

number which has been assigned to a thing, as in phone number or apartment number, or ZIP code number.

number one! ★★★★☆ NEO
一 (one) + 番 (number) = 一番 (number one!)

the best! Number one!

police box ★★★☆☆
交 (combine) + 番 (number) = 交番 (police box)

police box - a small shop in your neighborhood where police hang out and wait to help you or jail you.

thing in a row ★★★☆☆ KUNKUNCOUNTER
番 (number) + 目 (eye) = 番目 (thing in a row)

this is a term used in counting things in a row. For instance, in English we'd say "Second book from the right" or "Third shelf from the top" in Japanese, they'd say: 2番目のbook OR 4番目のshelf.
