What is Address Verification?

Address verification is the process of confirming that an address is accurate, complete, and corresponds to a real-world location. It involves cross-checking user-provided address data against official postal databases, geospatial datasets, and other reliable sources. This ensures that the address exists, is deliverable, and follows the correct format based on regional or international standards.

Using an address verification tool like Geoapify's Address Validation Solution helps businesses prevent errors, streamline deliveries, and improve customer satisfaction. By verifying an address before processing orders, companies can reduce failed deliveries, eliminate duplicate records, and maintain a clean and reliable database.

For businesses that rely on accurate shipping, billing, or user location data, implementing address verification ensures efficiency and reliability throughout their operations. Discover more through our Batch Geocoding Services.

The API response includes a ranking system that helps assess the accuracy and reliability of the matched address. Here’s what each field means:

• result_type: "building"`

  • Indicates that the API matched the address at the building level, meaning it identified a specific house or structure rather than just a street or city.

• Confidence Scores:
  These values range from 0 (low confidence) to 1 (high confidence) and indicate how well the input address matches the database.

  • confidence: 1 – The overall confidence level of the match (1 means the API is certain about the result).
  • confidence_city_level: 1 – High confidence that the city is correct.
  • confidence_street_level: 1 – High confidence that the street is correct.
  • confidence_building_level: 1 – High confidence that the house/building number is correct.

• match_type: "full_match"`

  • This indicates that the input address exactly matches a known address in the database without modifications or approximations.

• popularity: 1.71

  • This score represents how popular the geographical location is, based on statistical data from loaded map tiles for the region. Higher values indicate that the area is frequently accessed or referenced in mapping data.

Conclusion

Address validation and verification are critical for ensuring the accuracy of address data, improving operational efficiency, and enhancing customer satisfaction. Geoapify’s Address Validation API offers a reliable, efficient, and cost-effective solution for businesses of all sizes.
