Frequently Asked Questions

What Does an Unverified Address Mean?

It means the address entered is missing details, incorrect, or not recognized by postal databases. PostGrid checks addresses against trusted postal sources, like USPS and Canada Post, to find errors and suggest the correct format. This helps businesses reduce failed deliveries, avoid returned mail, and make sure customer addresses are complete and accurate.

How Can Businesses Standardize Address Data?

You can standardize address data by using PostGrid’s Address Verification service. It automatically fixes spelling mistakes, formats addresses correctly, and converts them into a standard postal format.

What Is an Example of a Deliverable Address?

A valid address includes the correct street name, house number, city, state, and ZIP code. For example: 221B 1st Street, Pasadena, CA 91107. PostGrid checks if an address is real, properly formatted, and deliverable, ensuring the last-mile delivery is successful.

How Is Address Validation Different From Address Verification?

Address validation checks if an address is correctly formatted and complete. Address verification goes further by confirming the address actually exists and can receive mail. PostGrid combines both processes to help businesses maintain accurate customer records, improve deliveries, and reduce failed shipments.

Does PostGrid Support CASS and SERP Certification?

Yes, PostGrid supports CASS and SERP-certified standards. These certifications show that the system follows postal guidelines for accurate address matching and formatting. Businesses can improve mailing accuracy and qualify for postal discounts by using a certified Address Verification service, like ours.

Can PostGrid Provide Additional Address Metadata?

Yes, PostGrid can provide helpful metadata along with verification results. This may include the delivery point validation code, residential or commercial indicators, census data, and geo-coordinates.

How Can You Verify International Addresses?

PostGrid allows businesses to validate international addresses using global postal databases. The system checks formatting, postal codes, and local address rules for different countries. This helps businesses reduce international shipping errors and maintain accurate customer records for 245+ countries and territories.

How Can Businesses Integrate PostGrid With Existing Systems?

PostGrid offers APIs and easy integration options for websites, CRMs, ecommerce platforms, and business applications. Businesses can connect the tool with their existing systems to validate addresses automatically in real-time. It reduces manual work and helps no-code teams to benefit from the service.
