U.S. stamp prices have moved steadily over the decades, shaped by postal regulation, technology shifts, and service expectations. Tracking these changes by year helps collectors, small businesses, and everyday senders understand real costs and policy impacts on mail.
This overview uses a structured summary and detailed sections to explain how domestic rates, forever stamps, and additional services have evolved since 2000.
| Year | First-Class Letter Rate (1 oz) | Forever Stamp Price | Key Change or Policy Note |
|---|---|---|---|
| 2000 | $0.34 | $0.34 | Stamps remain flat due to stable mail volume and pre-recent regulation caps. |
| 2007 | $0.39 | $0.39 | First increase in several years, citing rising transportation and fuel costs. |
| 2013 | $0.46 | $0.46 | Rate jump under new postal pricing rules that linked increases to inflation. |
| 2019 | $0.55 | $0.55 | Two-cent rise tied to market-dominant product adjustments and efficiency mandates. |
| 2023 | $0.66 | $0.66 | Larger increase aligned with recent regulatory changes and cost pressures. |
Domestic First-Class Mail Pricing Trends
The first-class letter rate sets the baseline for how much a standard 1 ounce letter costs to mail within the United States. Since 2000, the rate has generally trended upward, with small periodic bumps and a few larger jumps.
Regulators require the U.S. Postal Service to justify these increases through cost analyses and public notice. As a result, most changes by year are modest, but they add up for frequent shippers and nonprofit mailers who rely on stable pricing.
Forever Stamp Value and Rate Lock
A forever stamp is designed to cover the cost of a one-ounce first-class letter no matter when it is mailed. When the domestic first-class rate changes, the price of a forever stamp changes by the same amount.
This simplifies purchasing for senders, because they do not need to buy different denominations for future letters within the same weight class. The table above shows how the forever stamp price moved in lockstep with the letter rate across the years.
Additional Services and Market-Dominant Rates
Beyond basic first-class, the postal service offers market-dominant rates for larger envelopes, flats, and packages. These products are priced separately and often adjusted at different times than letter rates.
Small businesses that ship marketing materials or e-commerce orders watch these year-by-year changes closely, since higher rates can affect packaging choices, zone pricing, and overall shipping budgets.

FAQ
Reader questions
Why did U.S. stamp prices rise in 2013 and again in 2023
Rate increases in 2013 and 2023 were driven by updated regulatory pricing models, higher operational costs, and changes in mail volume, with 2023 reflecting more pronounced cost pressures across transportation and labor.
How does a forever stamp work if prices change
A forever stamp always equals the current one-ounce first-class letter rate, so if you buy it at $0.66, it will remain valid for a one-ounce letter regardless of future price increases.
Are there lower rates for nonprofit and educational mail
Yes, nonprofits and educational institutions often qualify for reduced first-class and periodical rates, though these discounts do not change the publicly listed standard prices shown by year.
Can I still use older forever stamps after a rate increase
You can, because a forever stamp purchased at a lower price is still accepted for a one-ounce letter even after the rate rises, which is the core value of the forever product.
