Overview

US Extract offers a set of APIs for validating and standardizing various forms of customer data. Established in 2005, the platform focuses on ensuring the accuracy and integrity of critical information such as addresses, email addresses, phone numbers, and names. This capability is relevant for businesses that manage large volumes of customer data, including e-commerce platforms, customer relationship management (CRM) systems, and logistics providers.

The core products include the Address Validation API, Email Validation API, Phone Validation API, and Name Validation API. These APIs are designed to be integrated into existing workflows to perform real-time verification or batch processing. For instance, the Address Validation API can correct typos, standardize formats, and append missing information like ZIP+4 codes, helping to reduce shipping errors and improve delivery rates. Similarly, the Email Validation API checks for syntax errors, disposable email addresses, and deliverability, which can help minimize bounce rates for marketing campaigns and prevent fraudulent sign-ups.

US Extract is suitable for use cases requiring high data quality. In e-commerce, it can prevent address-related shipping failures and enhance the customer checkout experience by auto-completing address fields. For CRM systems, it maintains clean contact records, which supports effective communication and data analysis. In fraud prevention, validating contact details can be a step in identifying suspicious transactions or user registrations. The company provides a RESTful API with JSON responses, and its documentation includes examples for common programming languages like Python and Node.js to assist developers in integration (US Extract API reference).

Compliance with data security and privacy standards, such as SOC 2 Type II and GDPR, is part of US Extract's operational framework. This can be a consideration for organizations handling personal data, as outlined by standards bodies like the Internet Engineering Task Force (IETF) in RFCs related to data privacy. The service offers a free tier for initial testing and evaluation, providing 500 lookups per month, with paid plans scaling based on usage volume.

Key features

  • Address Validation API: Verifies street addresses, standardizes formats, corrects errors, and appends missing data such as postal codes. This can reduce delivery failures and improve shipping efficiency.
  • Email Validation API: Checks email addresses for correct syntax, identifies disposable or temporary emails, and assesses deliverability status to reduce bounce rates and improve communication effectiveness.
  • Phone Validation API: Validates phone numbers internationally, identifies line types (e.g., mobile, landline), and detects invalid or disconnected numbers. This supports accurate contact lists for customer service and marketing.
  • Name Validation API: Assesses the validity and commonality of personal names, which can be used to detect fraudulent entries or standardize customer records.
  • Real-time and Batch Processing: Supports immediate validation during data entry and bulk processing for existing datasets, offering flexibility for various operational needs.
  • Developer SDKs: Provides client libraries for multiple programming languages including Python, Node.js, PHP, Ruby, Java, and .NET, to simplify API integration.
  • Compliance: Adheres to SOC 2 Type II and GDPR standards, addressing data security and privacy requirements for businesses operating globally.

  • Melissa: Provides a range of data quality solutions including address, email, and phone validation, as well as data enrichment.

Getting started

To begin using the US Extract API, you typically obtain an API key and then make HTTP requests to the appropriate endpoints. The following Python example demonstrates how to validate an address using the US Extract API.

import requests
import json

API_KEY = "YOUR_API_KEY"
ADDRESS_API_ENDPOINT = "https://api.usextract.com/v1/address/validate"

def validate_address(street, city, state, zipcode):
    headers = {
        "Content-Type": "application/json"
    }
    payload = {
        "api_key": API_KEY,
        "street": street,
        "city": city,
        "state": state,
        "zipcode": zipcode
    }
    
    try:
        response = requests.post(ADDRESS_API_ENDPOINT, headers=headers, data=json.dumps(payload))
        response.raise_for_status() # Raise an exception for HTTP errors
        return response.json()
    except requests.exceptions.HTTPError as http_err:
        print(f"HTTP error occurred: {http_err}")
        return None
    except Exception as err:
        print(f"Other error occurred: {err}")
        return None

# Example Usage
if __name__ == "__main__":
    address_to_validate = {
        "street": "1600 Amphitheatre Parkway",
        "city": "Mountain View",
        "state": "CA",
        "zipcode": "94043"
    }
    
    validation_result = validate_address(**address_to_validate)
    
    if validation_result:
        print("Address Validation Result:")
        print(json.dumps(validation_result, indent=2))
    else:
        print("Address validation failed.")

This Python script defines a function validate_address that sends a POST request to the US Extract Address Validation API endpoint with the provided address components and your API key. It then prints the JSON response, which typically includes the validation status, corrected address, and other relevant information. Replace "YOUR_API_KEY" with your actual API key obtained from the US Extract documentation.
