Lob Address Cleanser is a powerful tool designed to enhance the accuracy of shipping information, thereby reducing unnecessary shipping costs. It ensures that misspelled or incomplete addresses are corrected and validated while customers are still on the checkout screen, improving delivery success rates. By adhering to local postal formats like USPS in the United States, the app standardizes address data to minimize delivery mixups. Additionally, it flags any missing mandatory delivery fields, such as unit numbers and street suffixes, and distinguishes between P.O. Boxes and residential or commercial buildings. This proactive approach allows customers to be notified of address issues before completing their purchase, ensuring a seamless checkout experience. Furthermore, businesses can customize address verification popups to align with their store themes, thus maintaining brand consistency. Certified address data from USPS and worldwide postal carriers is utilized, guaranteeing reliable and precise deliveries.
