This code helpe me start my module.

For PS1.4.7.
I have one carrier that delivers only for certain zip-codes. All of them in the same state. Using default PS behaviour, a carrier is assigned for a zone... and the zone "is made" of states. We cannot divide states into smaller parts.

So, just in case someone need this, I figured out a simply way to achieve this.

• I added a zone for my collection of postcodes
• I set up a carrier fot that zone
