difference between priority mail and first class mail

difference between priority mail and first class mail lies in delivery speed, price, and weight restrictions. Priority Mail, provided by USPS, is designed for faster deliveries and usually arrives within 1 to 3 business days. It includes tracking, insurance up to $100, and is suitable for packages weighing up to 70 pounds. In contrast, First-Class Mail is intended for lightweight items under 16 ounces, with delivery times ranging from 2 to 5 business days and lower postage costs. While both options offer tracking, First-Class Mail is better for documents or small packages, whereas Priority Mail is ideal for more urgent or heavier shipments. Choosing the right option depends on delivery urgency, package weight, and shipping budget.
