FCM weighing over 13 ounces may be mailed in which class of mail?

FCM weighing over 13 ounces can be mailed using Priority Mail, which is specifically designed to handle packages that exceed the weight limit for First Class Mail. Under the regulations of the United States Postal Service (USPS), First Class Mail is limited to a maximum weight of 13 ounces for letters and is typically used for lighter correspondence.

Priority Mail, on the other hand, allows for heavier items up to 70 pounds and provides delivery service that is generally faster than Standard Mail and Ground Mail. It comes with additional benefits such as tracking and delivery updates, which are important for both senders and recipients when sending valuable or time-sensitive packages.

This distinction in weight limits and service levels is crucial for proper mail classification, ensuring that items are sent using the appropriate service to meet the needs of the sender and recipient effectively.
