When is it recommended to use certified mail instead of USPS Tracking?

Using certified mail is particularly recommended for letters and flats because it provides an additional level of service that ensures proof of mailing and delivery. This is essential for important documents that require verification that they have been sent and received, such as legal notifications or sensitive correspondence. Certified mail offers the sender a mailing receipt at the time of mailing, along with a record of delivery details.

While USPS Tracking is a valuable tool for monitoring the transit status of a package, it does not provide the same level of proof of delivery that certified mail does. Certified mail also includes a signature from the recipient upon delivery, which is a critical feature for many types of important documents.

In contrast, options like packages, Express Mail, or International Mail have different specifications regarding tracking and proof of delivery that may not align with the requirements that certified mail fulfills. Thus, for letters and flats, opting for certified mail ensures both security and peace of mind for sending important communications.
