Hreflang for regions (like states and provinces) within a country

by Brad Thiessen   Last Updated July 04, 2018 17:04 PM - source

I'm working on a website which has different content depending on the province/state the user is from.

Is it valid to add the subdivision code to the hreflang like below?

<link rel="alternate" hreflang="en-ca-ab" href=""/> 

If not, is there another way to let search engines know that the content is specific to a certain province/state?
