Please view the code given below. I think this will fulfill your requirement. I have found that you have use address.zipCode which has not been declared anywhere in given code so I have replace the address.zipCode with zipCode.

        int temp,zipCode;

        bool breakLoop = false;

        Console.WriteLine("Enter the the zip code of the contact.");

        while (breakLoop == false)
        {
            string userInput = Console.ReadLine();
            if (userInput.Length != 5)
            {
                Console.WriteLine("Error. Zip code is not 5 digits. Please enter a valid number.");
                continue;
            }

            int.TryParse(userInput, out temp);
            if (temp == 0)
            {
                Console.WriteLine("Error. Please enter a valid number.");
                continue;
            }                

            zipCode = temp;
            breakLoop = true;
            break;

        }

Please let me know if you have any problem with the code.
