US Post Code (ZIP) generator

Last modified: April 3, 2025

The US Post Code (ZIP) generator creates realistic five-digit ZIP Codes used in the United States postal system (e.g., 90210). These codes identify specific geographic regions or delivery points and are commonly used in applications that process, validate, or simulate US address data.

Generator properties

The table provides key details about the generator, including the short name, sample of the generated data, the supported data types, and whether it is specific to a particular country.

Short name	Example of generated data	Data type matching	Country-specific
ZIP	48470, 90189, …	charactercharacter varyingtext	Default

Matching rules

The generator can be assigned to a column that matches any of the following rules:

The column name contains ‘Zip’ or ‘Postal’, preceded or followed by any or no characters, and ends with ‘Code’, regardless of the table name.
The column name contains ‘Addr’, preceded or followed by any or no characters, and ends with ‘4’, regardless of the table name.

Configure additional options

The generator produces data based on a regular expression. Since it is built on the RegExp generator, see Regular Expression generator to customize settings and understand the correct usage of syntax.
