Understanding First-Class Mail Pricing in 2025
First-Class Mail remains the most common option for letters and lightweight flats. In 2025, a single first-class letter weighing up to 1 ounce now costs $0.68, up from $0.66 the previous year. Each additional ounce beyond the first adds $0.26, making it important to weigh your item before heading to the post office.
The postcard rate has also changed, increasing to $0.66 in 2025 to better align with first-class letter pricing. If your mailpiece qualifies as a standard letter or postcard and meets size and weight requirements, you can expect consistent pricing and delivery within one to three business days for domestic destinations.
Package and Priority Mail Costs in 2025
For heavier items and time-sensitive shipments, Priority Mail pricing adjustments are significant. A 1-pound package that previously cost $9.85 now starts at $10.10 in 2025. The updated Priority Mail Flat Rate pricing also reflects $9.95 for standard envelopes, slightly higher than the prior $9.65 rate.
These changes account for rising transportation and fuel expenses, as well as investments in faster delivery networks. If you regularly ship packages, comparing Priority Mail rates with other carriers and retail postage prices can help reduce overall shipping costs.
International and Additional Services Overview
