In the US, five-digit zip codes are part of the US Census boundary system, 
and - as public boundaries - are open for download.

In most other countries, the boundaries of postal code areas are not 
public data, even where the postal service is public, and are usually only 
available at substantial cost, and often without permission to publish 
maps based on the boundaries.

In Norway, a Meteorological Office programmer crowd-sourced point 
locations to provide a way of offering weather forecast look-up based on 
postcode - but those are not boundaries, and indeed are just the GPS 
readings of volunteered data.

Even using commercial APIs to give address points probably will not help.
