Determine Domestic Address format when searching with Google autocomplete

[devjk1]

The issue with Google autocomplete on Places API is
if we search without a 'street number', API will return partial addresses (e.g. no street number, no zip too IIRC)
if we search with a 'street number', we can get a full address, then store directly.

Another issue is determining if complete addresses can start without a number (e.g. PO box, if we store those)
if we do store addresses that start without a number, we could

• make another form and fields for those edge cases (e.g. user checks PO box checkbox, and we show a different form)
• backend-validate response contains all fields.. this could mean we have a 'complete address'

if we only store addresses that start with a number, we can

• frontend-validate query on starts with a number, then store response directly as DomesticAddress model

After a cursory search, I believe complete addresses need a street number. Whether or not 'street numbers' can start with a letter is another concern.
