# Get States by Country

> Retrieve all states/provinces for a specific country

Retrieve all states, provinces, regions, and territories for a specific country using the country's ISO2 code.

<Note>**Availability:** All plans (Community and above). The fields returned vary by tier — see **Tier-Based Field Availability** below.</Note>

## Path Parameters

<ParamField path="iso2" type="string" required>
  ISO2 code of the country (e.g., "IN" for India, "US" for United States)
</ParamField>

<Tip>
  **Trim and order results:** Add `?fields=` to limit columns returned, or `?sort=` to order the list. Both are available on **Supporter+** plans. See the [Field Filtering & Sorting](/api/field-filtering-and-sorting) guide for syntax and per-entity sortable fields.
</Tip>

## Authentication

<ParamField header="X-CSCAPI-KEY" type="string" required>
  Your API key for authentication
</ParamField>

## Query Parameters

<ParamField query="q" type="string">
  Search filter on name. Case-insensitive match on `name` and `native` fields. Minimum 2 characters. **Requires Supporter+ plan.** Without this parameter, all results are returned (no plan restriction for search).
</ParamField>

## Response

<ResponseField name="id" type="integer">
  Unique identifier for the state/province
</ResponseField>

<ResponseField name="name" type="string">
  Official name of the state/province
</ResponseField>

<ResponseField name="iso2" type="string">
  ISO2 code for the state/province
</ResponseField>

<ResponseField name="country_id" type="integer">
  Unique identifier of the parent country
</ResponseField>

<ResponseField name="country_code" type="string">
  ISO2 code of the parent country
</ResponseField>

<ResponseField name="latitude" type="string">
  Approximate latitude of the state/province
</ResponseField>

<ResponseField name="longitude" type="string">
  Approximate longitude of the state/province
</ResponseField>

<ResponseField name="timezone" type="string">
  IANA timezone identifier (e.g., `"Asia/Kolkata"`)
</ResponseField>

<Info>Additional fields like `fips_code`, `iso3166_2`, `type`, `level`, `parent_id`, `native`, `population`, `translations`, and `wikiDataId` are returned on higher tiers. See **Tier-Based Field Availability** below.</Info>

## Common Use Cases

<AccordionGroup>
  <Accordion title="Cascading Address Forms">
    Create dependent dropdowns where states populate based on country selection.

    ```javascript theme={null}
    const populateStatesDropdown = async (countryCode) => {
      const states = await getStatesByCountry(countryCode);
      const select = document.getElementById('state-select');
      
      // Clear existing options
      select.innerHTML = '<option value="">Select State...</option>';
      
      states.forEach(state => {
        const option = document.createElement('option');
        option.value = state.iso2;
        option.textContent = state.name;
        select.appendChild(option);
      });
    };

    // Listen for country changes
    document.getElementById('country-select').addEventListener('change', (e) => {
      populateStatesDropdown(e.target.value);
    });
    ```
  </Accordion>

  <Accordion title="Regional Validation">
    Validate state codes against specific countries.

    ```javascript theme={null}
    const validateStateForCountry = async (countryCode, stateCode) => {
      const states = await getStatesByCountry(countryCode);
      return states.some(state => state.iso2 === stateCode);
    };
    ```
  </Accordion>
</AccordionGroup>

<Tip>
  Cache states by country as they rarely change. Use this endpoint instead of filtering all states for better performance.
