is priority mail faster than first class is a question many people ask when deciding between USPS shipping options. Priority Mail is typically faster than First-Class Mail, with a guaranteed delivery time of 1-3 business days for domestic shipments. In contrast, First-Class Mail can take anywhere from 1 to 5 business days, depending on the destination. Priority Mail also includes additional benefits like free tracking, up to $50 in insurance coverage, and a wider range of package sizes. For time-sensitive shipments, Priority Mail is generally the better choice, while First-Class Mail is more affordable and suited for smaller, non-urgent packages.
