With the introduction of Lookup, businesses can now retrieve detailed information about a phone number, reducing spam and improving deliverability by presenting numbers in the most local-friendly manner. This API allows users to identify and adjust international phone numbers into national formats, ensuring that they are presented in a visually appealing way. Additionally, it helps reduce spam by identifying invalid or suspicious phone number entries, and improves deliverability by providing information on carrier and type of phone numbers, enabling businesses to recognize when alternative delivery methods may be needed.
