what’s the difference between priority mail and first-class mail

what’s the difference between priority mail and first-class mail Priority Mail and First-Class Mail are two common shipping services offered by the United States Postal Service (USPS), each with distinct features. Priority Mail is typically used for packages that weigh over 13 ounces, and it offers faster delivery within 1–3 business days, along with free tracking and insurance for packages up to $50. First-Class Mail, on the other hand, is primarily used for letters and small packages weighing up to 13 ounces, offering a more affordable option with delivery within 1–5 business days. The choice between these services depends on the size, weight, and urgency of the shipment, with Priority Mail being more suitable for heavier, time-sensitive parcels.
