Current First Class Stamp Pricing in 2025
The price of a first class stamp in 2025 is 66 cents for a standard letter weighing up to one ounce. This is the most common rate for personal and small business mailers who need predictable, timely delivery without extra services.
Each additional ounce beyond the first typically adds 26 cents, so a large letter weighing up to two ounces costs 98 cents, and items up to three ounces cost $1.30. These step rates apply to envelopes and flats that meet size and thickness standards for first class mail.
Metered vs Individually Printed Stamps
Metered Postage Benefits
Purchasing postage through a digital meter or an approved online meter provider can lower the effective cost per piece and provide built-in tracking. Metered stamps use discounted first class rates and are ideal for consistent, high-volume mailers.
Individually Printed Stamps
Buying a single first class stamp at a post office or retail counter still costs 66 cents for standard letters in 2025. Bulk booklets may offer slight savings per piece, but they are less flexible than calibrated postage that matches exact weight and destination.
International and Special Destinations
First Class International Pricing
For international first class, the price varies by destination and is often calculated in local currency or based on flat-rate international envelopes. Delivery ranges from 7 to 21 business days, depending on customs and transport routes.
Additional Services and Add-ons
Options such as Certified Mail, Return Receipt, and Insurance increase total cost but provide proof of delivery and security. These services are billed separately or included in metered postage plans depending on the provider.
Alternatives to First Class Mail
Marketing Mail and Standard Post
Non-urgent pieces like flyers and catalogs can qualify for lower Marketing Mail rates, which are cheaper per piece but come with longer delivery timeframes and limited tracking compared to first class.
Priority Mail and Express Options
When faster delivery is needed, Priority Mail flat rates or Express services provide next-day to two-day transit with tracking. These options cost more than first class but are competitive for time-sensitive items.
