# Get Cities by Country

> Retrieve all cities within a specific country

Retrieve all cities within a specific country using the country's ISO2 code. This endpoint is useful for building location selectors and geographical applications.

## 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 city
</ResponseField>

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

<Info>City responses on the **Basic** tier only return `id` and `name`. Upgrading to **Supporter+** unlocks `state_id`, `state_code`, `country_id`, `country_code`, `latitude`, `longitude`, `timezone`, `population`, `type`, `level`, `parent_id`, and `native`. **Professional+** adds `translations` and `wikiDataId`. See **Tier-Based Field Availability** below.</Info>

<Note>**Availability:** `/countries/{iso2}/cities` (all cities in a country) requires **Supporter+**. Community/Starter users must use [Get Cities by State](/api/endpoints/get-cities-by-state) instead.</Note>

## Common Use Cases

<AccordionGroup>
  <Accordion title="City Autocomplete">
    Implement type-ahead city search for a specific country.

    ```javascript theme={null}
    class CountryCityAutocomplete {
      constructor(countryCode) {
        this.countryCode = countryCode;
        this.cities = [];
        this.loadCities();
      }
      
      async loadCities() {
        this.cities = await getCitiesByCountry(this.countryCode);
      }
      
      search(query) {
        const lowerQuery = query.toLowerCase();
        return this.cities.filter(city => 
          city.name.toLowerCase().includes(lowerQuery)
        ).slice(0, 10);
      }
      
      setupAutocomplete(inputElement) {
        inputElement.addEventListener('input', (e) => {
          const results = this.search(e.target.value);
          // Display results in dropdown
          this.displaySuggestions(results);
        });
      }
    }
    ```
  </Accordion>

  <Accordion title="Delivery Zone Setup">
    Group cities for shipping or service area calculations.

    ```javascript theme={null}
    const setupDeliveryZones = async (countryCode) => {
      const cities = await getCitiesByCountry(countryCode);
      
      // Group cities alphabetically for easier management
      const zones = cities.reduce((acc, city) => {
        const firstLetter = city.name.charAt(0).toUpperCase();
        acc[firstLetter] = acc[firstLetter] || [];
        acc[firstLetter].push(city);
        return acc;
      }, {});
      
      return zones;
    };
    ```
  </Accordion>
</AccordionGroup>

<Warning>
  **Large Datasets**: Countries like the United States, India, and China have thousands of cities. Consider implementing pagination or using the state-filtered endpoint for better performance.
</Warning>

<Tip>
  For better user experience, consider loading cities by state instead of by country for countries with many administrative divisions.
