First-class mail is used for postcards, letters, large envelopes, and small packages. First-class mail must weigh 13 ounces or less. Pieces over 13 ounces can be sent as Priority Mail. USPS first-class delivery is given priority over standard mail, and local mail will typically be delivered in 2-3 days.
