Is the postal code of Pakistan 0092?

Answer 1

No, Pakistan is a large country and has many different postal codes, not just one!

+92 is the telephone country code for Pakistan. This would be dialed as 0092 or 01192 from many countries.

(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.)
