-	ZipCodeInfo.instance.state_for "99163"
-	#=> WA
+```ruby
+  ZipCodeInfo.instance.state_for '99163'
+  #=> WA
+```
 
-	ZipCodeInfo.instance.scf_city_for "99163"

 * The city returned is the city where the USPS Sectional Center Facility (SCF) is located.
 * Sometimes the state that a zip code is bound to for USPS is different from the actual state the zip code is in. There are plans to provide both states.
