# Zipcode flows

In order to elicit a postalcode from the user, you could use for instance the Ask: open or Ask: number nodes, depending on the format of your postalcode. However, if you really want a valid postalcode check, this skill helps you do just that by introducing a node to your Flow designer that will ask a postalcode and check the validity.

## Installing the Zipcode flows skill

1. Go to packages 
2. Click on Browse skills
3. Click on the corresponding tile
4. Click install
