Mail pkpu

I think you meant to type "mail.pkpu"!

PKPU is a Pakistani postal code system, and "mail.pkpu" is likely a request to find the postal code for a specific location in Pakistan.

To help you with that, I'll need more information. Could you please provide the city or town name, or the province (Punjab, Sindh, Khyber Pakhtunkhwa, Balochistan, or Gilgit-Baltistan) where you're looking for the postal code?

Once I have that information, I can help you find the correct postal code for your location.
