Transposing Numbers: Simple errors like transposing digits (e.g., writing 60149 instead of 60148) can lead to misrouted mail. Always double-check the numbers.
Using Old Information: Relying on outdated directories or websites can result in using incorrect zip codes. Always use the USPS website as the primary source for zip code information.
