+```
+
+_Note:_ Use regex for validating phone numbers **only** if you don’t have the choice to use a library. There are [several libraries](https://stackoverflow.com/a/15644461/4717533) that handle phone numbers more accurately and should be used instead.

+```
+/^(.+)/(\[^/\]+)$/

+/^\[\\w,\\s-\]+\\.\[A-Za-z\]{3}$/

+
+### Additional Regexes
+
+#### 1\. Zip codes
+
+There is **NO** single Regex that can handle all zip codes given that zip codes around the world do not follow a common pattern. Here is a [list](https://stackoverflow.com/a/7185241/4717533) that contains Regex specific to each country.
+
+#### 2\. Payment Validation
