Geocoding API: Meaning, Use Cases, and How to Best Use It

What is a Geocoding API?

A geocoding API is an application programming interface service that converts a full address into Latitude and Longitude coordinates. Alternatively, a reverse geocoding API converts latitude and longitude data into a full address.

A geocoding API is a must-have for almost all industries and businesses. It returns accurate and valid addresses with their latitudinal and longitudinal data.

For example, you can get the coordinates “40.758896, -73.985130” for the Times Square in New York City.

You can use PostGrid’s industry leading address verification API to get access to geocoding API and reverse geocoding API.

But what is a geocoding API, and how to use it?

This blog answers this question, providing deeper insights into the subject and helping businesses incorporate geocoding into their everyday operations.

What Are Geocoding and Reverse Geocoding APIs?

Geocoding provides the geographic coordinates associated with a given postal address, offering significant advantages to businesses. Some benefits of using an API for geocoding include

  • Integrating geographical data into your customer database, 
  • Enabling location analytics and 
  • Validating postal addresses in payment and shipment forms.

In addition to coordinates, the API furnishes essential details about each location, like the timezone and well-organized, formatted addresses. Moreover, it modifies incorrect addresses, errors, or misspellings.

Reverse geocoding involves converting a location specified by geographic coordinates (latitude, longitude) into a human-readable address or place name. 

In contrast to forward geocoding, reverse geocoding enables the identification of nearby street addresses, places, and areal subdivisions such as neighborhoods, counties, states, or countries.

Many people confuse the geocoding and reverse geocoding API because they sound similar. However, they perform different functions. Luckily, you can do both using a single platform, like PostGrid.

The primary goal of the reverse geocoding API is to answer questions like “What’s here?” or, if the location is not directly on top of a feature, “What’s near this location?” 

Reverse geocoding returns the most relevant feature near an input location based on a prioritized hierarchy of feature types to answer it.

Companies have many reasons for maintaining records of physical addresses. However, organizing this information according to the unique postal standards of countries worldwide can be impractical. Hence, geocodes come into play.

Geocodes serve as a universal standard for identifying locations anywhere in the world. They use latitudes and longitudes to find applications in developing third-party apps, enabling site-to-store features in eCommerce experiences, and facilitating logistics planning. 

The API for geocoding also holds significance in disaster preparedness, primarily in regions experiencing weather-related disruptions. Latitude and longitude data can aid in detecting challenges to public health. Geocoding becomes the sole means to identify or describe a location, primarily in areas lacking formal address systems. Partnering with an API development company can further enhance the functionality and reliability of geocoding services, ensuring businesses have access to precise and up-to-date geographical data for their critical operations.

Geocoding API Use Cases

Converting addresses into coordinates and mapping locations proves advantageous for your business, fostering improved targeting, strategic planning, and ultimately – revenue growth. It provides accurate data for visualization and facilitates customer satisfaction and delivery logistics.

Businesses use the geocoding API for many reasons. But some of the best applications are:

PostGrid’s geocoding tool converts addresses from your customer databases into corresponding coordinates. Thus, it simplifies using your data for location-based marketing and analytics. 

For example, companies use an API for geocoding to determine their customers’ density in cities or localities. It lets them plan product launches or marketing campaigns accordingly.

Identify Patterns

Geocoding a sufficient number of addresses in specific areas and plotting them enables you to identify patterns based on the data. Recognizing clusters in particular regions can dictate your marketing and retail strategies.

Validate Payment or Shipment Addresses

Address validation, or verification, involves confirming the correctness and deliverability of customer addresses. 

Fortunately – PostGrid’s geocoding API also lets you standardize and cross-check mailing addresses against the USPS CASS and NCOA databases.
