Which service provides a quick lookup for ZIP Codes and other postal services?

The choice of Usps.com is correct because it serves as the official website of the United States Postal Service and provides a comprehensive tool for a variety of postal services, including ZIP Code lookups. Users can easily access the ZIP Code lookup tool online along with other features like tracking packages, finding postage rates, and locating post office services.

This platform is designed for convenience, allowing customers to retrieve postal information quickly and efficiently. It centralizes multiple services which makes it an ideal resource for those needing quick access to postal information from any device with internet access. Other options may offer similar services but do not encapsulate the full range of features available on the official USPS website. For instance, while the mobile app might have similar functionality, it does not serve as the main informational hub that Usps.com provides.
