What the US Stamp Price Was in 2018
In 2018, the standard First-Class Mail letter rate for a 1-ounce letter sold at a post office remained unchanged from 2017. The United States Postal Service (USPS) kept the First-Class stamp price at $0.50 for 1-ounce letters. A Forever stamp purchased in 2018 continued to provide a 1-ounce letter mailing capability, with additional ounces and larger letters or flats priced according to published USPS schedule. These rates reflected the pricing environment before the 2019 increases and were set by the Postal Regulatory Commission and approved by the USPS Board of Governors.
Historical Context and Timing
USPS pricing follows a regulated cycle, with rates typically adjusted annually. The 2018 rates were set to stabilize costs for consumers while accounting for ongoing operational expenses. Because 2018 did not include a rate change, the prices remained consistent throughout most of the year. It was not until January 2019 that new postage rates took effect, marking the next change after the 2018 baseline.

Understanding Forever Stamps in 2018
A Forever stamp bought in 2018 was valid for mailing a 1-ounce First-Class letter regardless of future price increases. This characteristic makes Forever stamps a practical option for consumers who anticipate sending letters over time. However, for postcards, additional-ounce charges, or large envelopes, specific postage remained required to meet delivery specifications.
Forever Stamp vs Single Stamp
- Forever stamp: Covers 1-ounce First-Class letter indefinitely.
- Single First-Class stamp (2018): $0.50, same coverage as Forever for 1 ounce.
- Additional ounce: $0.21 per extra ounce when weight exceeds 1 ounce.
- Postcard rate: Typically $0.34 for non-government metered postcards.
Where to Verify 2018 US Stamp Prices
Because historical rates can be misremembered or approximated, rely on authoritative sources when confirming 2018 pricing. The USPS official website, the Postal Regulatory Commission records, and archived rate charts published by USPS provide definitive references. Avoid generalized summaries that do not cite exact dates or regulatory filings.
Practical Implications and Consumer Guidance
Knowing the 2018 US stamp price helps with expense tracking, budgeting retrospectives, or evaluating mailing options during that year. For current mailing needs, always check the latest USPS rate chart because prices evolve with operational and regulatory conditions. When comparing past and present, note both the nominal face value and the real-cost implications of rate changes over time.
