ISOCodex.Addressing.UnitedStates

Public documentation and support

Version 2.1.1 targets netstandard2.0 for .NET Framework 4.7.2+ and modern .NET, replacing the redundant netstandard2.1 asset. The matching core requires ISOCodex.Countries 1.1.1 or later.

United States-specific extension package for ISOCodex.Addressing.

Installation

dotnet add package ISOCodex.Addressing.UnitedStates

Registration

services.AddAddressing();
services.AddUnitedStatesAddressing();

What it provides

  • US validator registration.
  • United States address formatter.
  • United States address profile metadata for forms.
  • ZIP and ZIP+4 validation.
  • USPS state, territory, possession, and military-code validation.

Validation is structural. It does not call external services and does not prove that an address exists or is deliverable. It does not cross-check city, state, and ZIP combinations.

Example

`csharp using ISOCodex.Countries;

var address = new Address( "1600 Pennsylvania Avenue NW", null, "Washington", "DC", new PostalCode("20500"), CountryAlpha2Code.Parse("US"));


Formatted output:

```text
1600 Pennsylvania Avenue NW
Washington, DC 20500
United States
