Are stamps first class mail

In the United States, the term "First-Class Mail" refers to a type of mail service provided by the United States Postal Service (USPS). First-Class Mail is a category of mail that includes letters, postcards, and lightweight packages that are sent to destinations within the United States.

In general, stamps are used to pay for the postage of First-Class Mail items. The cost of postage for First-Class Mail items depends on the weight and size of the item, as well as the distance it is being sent.

Here are some general guidelines on what is considered First-Class Mail and what is not:

First-Class Mail:

• Letters and postcards weighing up to 1 ounce
• Lightweight packages weighing up to 13 ounces
• Items sent within the United States, including to and from military addresses
• Items sent to U.S. territories, such as Puerto Rico and Guam

Not First-Class Mail:

• Packages weighing more than 13 ounces (these are considered Priority Mail or Parcel Post)
• Items sent to international destinations (these are considered International Mail)
• Items sent using special services, such as Certified Mail or Registered Mail
• Items sent using airmail or surface mail (these are considered International Mail)

It's worth noting that while stamps are often used to pay for First-Class Mail postage, you can also use a postage meter or online postage services to pay for your mail. Additionally, the USPS offers a variety of postage rates and discounts for bulk mailings and other types of mail.
