At lest in that particular case, the postal code is the same (LV-3401) for both streets.
Coincidentally, at least here, the official addresses are guaranteed to be unique, a city/town can not have two streets with the same name (at least at any single point of time, renaming over centuries gets weird) - naming streets and assigning numbers to houses is not an arbitrary decision that the landowner can make, it is managed/coordinated centrally.
