009234 which country and area no?

Answer 1

00 isn't part of the country code, it is a commonly used international access prefix. Country code +92 is Pakistan, and a number beginning with +92 3 is a mobile.

Alternatively, a few countries use 009 as an international access prefix, which would leave country code +234, Nigeria.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)
