Geocode - Amazon Location Service

Geocode

Geocoding transforms textual addresses or place names into geographic coordinates, along with detailed address components and additional information. This API supports flexible queries, including both free-form text and structured queries with street names, postal codes, and regions. Optional features include time zone data and political view adjustments.

Note

Stored results incur higher Storage pricing. Use the IntendedUse parameter to indicate single-use or storage. Refer to the Places pricing to understand cost implications for stored results.

For more information, see Geocode in the Amazon Location Service API Reference.

For example requests, responses, cURL, and CLI commands for this API, see How to use Geocode.

Use cases

  • Add supplementary data to customer addresses: Improve address records by including zip codes, coordinates, and utilizing persistent storage to support informed business and marketing decisions.

  • Address Data Standardization: Apply geocoding in data pipelines or batch processes to standardize address data, utilizing persistent storage for ongoing reference.

  • Determine Time Zones: Identify the time zone for cities or addresses to provide accurate timestamps for applications like travel, scheduling, and invoicing.

Additional Features

Request additional information like time zone details.

  • AdditionalFeatures: Option to request additional details such as time zone. For more information, see Additional features.

Understand the response

The response provides ResultItems, which contain detailed location data such as Address, PlaceId, Position, and other relevant attributes. Additional features like TimeZone information or MatchScores for each query component may also be included. Each ResultItem represents a matched location or geocoding result based on the specified request parameters. For further details, see the Geocode API Reference.

The response includes the following key parameters:

Address and related details

Details about the returned location, including address components.

  • Address: Full address including country, region, postal code, and street details.

  • PostalCodeDetails: Additional information related to postal codes.

  • StreetComponents: Street details including base name and type.

Place types and categories

Information on the type and category of place returned.

  • Categories: List of categories describing the place, for example Restaurants, Schools.

  • PlaceType: Specifies the type of place, such as city, address, or region.

Result analysis

Scores indicating how closely results match the input query.

  • MatchScores: Scores for matching precision.

    • Overall: Measures how well an address search matches your input, on a scale from 0.0 to 1.0 (0% to 100%). A perfect score of 1.0 means every part of your search was found in the database. It's normal to see lower scores when including extra details like contact names or delivery instructions. These naturally reduce the score, but don't necessarily mean the address is wrong.

    • Component Score: Each address component (such as AddressNumber or PostalCode) is scored individually on a scale from 0.0 to 1.0 (0% to 100%). These scores indicate how accurately each part of the address matches the result. For example, if AddressNumber, Street, and PostalCode score close to 1.0, you can trust the match even if the overall score is lower due to other query details.

    Note

    When no score appears for a specific component (such as Street), that component is counted as 0. This helps identify parts of the address that might need verification.

    This scoring system helps balance between exact matches and practical usability when dealing with real-world address searches that often include extra information.

Additional details

Includes extra location-related information as needed.

  • AccessPoints: Geographic coordinates representing access points.

  • TimeZone: Time zone information for the location.
