Current Cost of a First Class Stamp (As of June 2025)

The U.S. Postal Service (USPS) tweaks rates now and then to keep pace with inflation and rising costs. The most recent bump hit in January 2025, when the price moved up from 68 cents to the current 73 cents.

What Does a First Class Stamp Cover?

A First-Class stamp lets you send any standard, flat envelope to any address inside the U.S. Heres what it covers in plain terms:

Size: Rectangular mail that measures between 3.5 x 5 inches and 6.125 x 11.5 inches

Weight: Up to 1 ounce

Delivery Time: Usually lands in 1 to 5 business days

People use First-Class for letters to friends, birthday cards, billing statements, and quick small-business mail. Its a reliable, speedy service that doesnt break the bank.

Where to Buy First Class Stamps

First-Class stamps are easy to get-if you know where to look.

• USPS post offices across the country
• USPS.com, delivered right to your doorstep
• Grocery stores, pharmacies, and office-supply shops that have been authorized by the Postal Service
• Self-service stamp kiosks found inside some post offices and in public areas

Buying in bulk-a 20-stamp booklet or a coil of 100-is handy and usually offers a fun design.

Why Do Stamp Prices Increase?

Stamp prices go up mostly because inflation hits everyone and the Postal Service has to cover higher day-to-day costs. Theres nothing cheap about fuel, labor, trucks, or even the paper and ink used for each stamp. On top of that, the USPS earns less money now because people send fewer letters and choose email or texts instead.

Before any new price takes effect, the Postal Regulatory Commission, or PRC, steps in to review and approve the change. The agency wants rates to be fair, so it gives advance notice-usually months ahead-so customers and businesses can adjust.

Conclusion

As of June 2025, a First-Class stamp in the U.S. costs 73 cents. That tiny charge slips into everyday life because people stick it on birthday cards, bills, or quick business notes without thinking twice.

Knowing what that rate covers, when extra postage kicks in, and how Forever Stamps save trouble keeps your letters moving on time-and saves you the headache of unexpected fees.
