street-number format
Addresses written with the street name first, then the house number, without a comma.
The street-number format describes addresses in which the street name is written first, followed (if available) by the generic street type ("Avenue", "Boulevard", etc.), then followed (without a comma) by the house number.
The street expression comes before the house number without a comma between them. When a generic street type is present, it remains with the street name ahead of the number.
The street-comma-number format has the same broad order with a comma added. The distinction concerns the written expression of an address.
