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.
When reading numbers in order, such as a telephone number or serial number (序列号), British people will usually use the term double followed by the repeated number. Thus 007 is double oh seven. Exceptions include the emergency telephone number 999, which is always nine nine nine. In the US, 911 (the US emergency telephone number) is usually read nine one one, while 9/11 (in reference to the September 11, 2001 attacks) is usually read nine eleven.
