 ## How to get the source argument
 
-The source argument is simply the house mailing address. Road type (eg. St, Ave) and cardinal direction if applicable (eg. N/S/NW) are required, so "501 23rd Ave" and "501 23rd Ave E" will give different results.

+The street_address argument is simply the house mailing address. Road type (eg. St, Ave) and cardinal direction if applicable (eg. N/S/NW) are required, so "501 23rd Ave" and "501 23rd Ave E" will give different results.
+
+If the service cannot be identified based on street address alone (in some multi-family houses, etc), a `prem_code` can be extracted by inspecting the "findAccount" call when looking up your service on the Collection Calendar.
