Just a heads up for everyone living in Hawally. I was renewing some documents on a government portal and got completely stuck because I didn't have the exact postal code. I kept using the general area name, but the system strictly requires the full five digit number. I had to quickly search and learned that the Hawally Postal Code isn't just one number for the whole area. For instance, the city centre uses 30000, but it changes depending on your specific block or PO Box number range. Save yourself the headache and make sure you know the correct one for your exact location before you start any online application.
