How generation works
Coherent geography
Locality, region, and postal code are selected from one relationship record.
Country-aware premise details
For countries not backed by real premise data, premise and street details are generated with country-aware rules.
Browser-local generation
After the data chunk loads, generation and regeneration run in your browser.
New Zealand postcode format
The four-digit postcode stays attached to its source locality and region; premise details are synthetic.
New Zealand address format
New Zealand results combine a synthetic street with locality, region, and a four-digit postcode.

Frequently asked questions
Is every complete address guaranteed to exist?
Not necessarily. Locality, region, and postal relationships are preserved, but premise and street details may be generated with country-aware rules where real premise data is not used.
Can the locality, region, and postal code be unrelated?
The generator reads all three fields from the same geography relationship record instead of randomizing them independently.
How many digits are in a New Zealand postcode?
The generator returns a four-digit postcode.
Are locality and region selected together?
Yes. They remain attached to the same source relationship as the postcode.
Are the generated premises real properties?
No. Premise details are synthetic and intended for testing.
Locality and regional relationships
The locality, region, and postcode are taken from one source relationship and remain together when filters change.
Premise fields are generated for test-data shape and are not verified New Zealand delivery addresses.
