<p>Not accurate. Per the USPS for domestic mail: “Registered mail is a highly secure form of delivery that is documented at each step of the way. Registered mail is best for sending documents or items that have an intrinsic value, where security is important. Mail takes approximately one day longer than certified mail to arrive as it has to be accounted for at each step along the way. This mail is kept under lock and key during its journey.”</p>
<p>It takes substantially longer for international registered mail. I don’t call one day a substantial delay for domestic.</p>
