Using the correct zip code is vital for ensuring that your mail arrives on time. Incorrect zip codes can lead to delays, misdelivery, or even the loss of your mail. For businesses, accurate zip codes are essential for targeted marketing, shipping logistics, and customer data management. Also, accurate zip codes are essential for accessing local services and information.
