I have a zip code problem on the Lancome site?

So, I have typed in the boxes my name, address, city, state and phone number, but when I introduce the zip code it says it is incorrect. I am not from US and I have typed in the zip code from my address. I assure you it is the correct one. Help?|||The main Lancome site only ships to the US. Use your country's designated site. If it is not listed/ can not be shipped to order through ebay, etc. or visit a counter.
