is usps priority faster than first class is a common question for people deciding between two of USPS’s most popular mail services. USPS Priority Mail typically delivers within 1-3 business days, while First-Class Mail is generally used for lighter and smaller packages and typically takes 1-5 business days. Priority Mail offers faster delivery and includes additional features such as tracking, insurance, and delivery confirmation. First-Class Mail, on the other hand, is usually more affordable but slower and doesn’t offer the same range of services.
