Postal Letter

how do I find out my postal code?

Is there a website I can just go to; enter a zip code, convert the number, and give me a postal code?

1. I do not understand your question. In the US, the zip code is the postal code. You would not need to convert it. Are you looking for international postal codes? Try going to the US Postal Service website - you can look up postal codes for foreign countries there.
2. Try the zip code search engine below. http://zipcodesearch.appspot.com/
