Fixed location and dependent filters
Country is fixed to the United States and state to New Hampshire (NH); choose among the sampled cities in this state. Changing city clears the previous postal filter. Every generated row must satisfy the selected state, city and ZIP together. An unavailable combination never falls back to nationwide random data. Shares from other locations are rejected.
An address-line fixture for NH
The street below is fictional; Derry, NH and 03038 retain their source association. Store the state abbreviation separately and ZIP as text. This example starts with zero, so import the ZIP column as text in spreadsheets. This tool does not generate ZIP+4 delivery units or establish deliverability.

Reproduce this location through the API
The same catalog version, filters and seed return the same result. The API permits up to 100 records and browser batches up to 1,000. Repeated ZIP codes are allowed; streets and identities remain synthetic. City and postal parameters must match this sampled catalog; arbitrary address lookup is not supported.

When you need broader ZIP references
This generator retains its existing sampled catalog for seed compatibility. The separate postal tools use a larger US source snapshot, support city and reverse-ZIP searches, and can generate a matching synthetic address from a selected reference. Coverage differs between datasets; neither verifies delivery or identifies a resident.
