2018 Postage Stamp Pricing Overview
In 2018, the cost of a U.S. postage stamp followed long-standing pricing rules set by the Postal Regulatory Commission and the United States Postal Service. A Forever stamp sold for $0.50, unchanged from 2017, while a single-piece First-Class letter (up to 1 oz) also remained at $0.50 to send. These prices reflected a pause in nominal increases after several earlier adjustments. This guide explains the specific 2018 rates, how to purchase stamps, and how international and additional-service pricing compared.
What Is a Forever Stamp in 2018?
The Forever stamp is designed to cover the cost of a one-ounce First-Class letter regardless of future price changes. In 2018, the Forever stamp price held steady at $0.50. This stability meant customers who bought Forever stamps in prior years did not need to top up when mailing 1-ounce letters. The Postal Service maintains that the real value of a Forever stamp can differ from its nominal price when weighed against inflation and delivery costs.

Where to Buy Stamps in 2018
Customers could buy stamps from multiple channels in 2018, each with slight availability and pricing nuances. The USPS retail counter and official online store listed $0.50 for a single Forever stamp. Retail partners such as grocery chains and pharmacies often sold booklets of 20 at a slight discount per stamp. Vending machines in offices and transit stations provided 24/7 access, though they sometimes sold only limited denominations. Buying booklets or larger rolls typically lowered the effective cost per stamp, which was useful for frequent senders.
Rate Changes Leading Into and Out of 2018
Prior to 2018, the cost of a Forever stamp increased almost annually, making 2018’s steadiness notable. In 2017, the Forever stamp was also $0.50, following a $0.49 price in 2016. The Postal Service implemented modest increases in earlier years to offset rising operational and transportation expenses. By 2019, rates nudged upward again, with the Forever stamp rising to $0.55. The 2018 pause represented a short-term stabilization in nominal pricing, while inflation and volume shifts continued to affect the real economics of mail delivery.
Special and International Pricing in 2018
While First-Class letter rates stayed level in 2018, other services and international options carried distinct price structures. Airmail to many countries typically required $1.15 for a single-letter sheet, and higher-weight international parcels were priced per pound using specific international rate tiers. Periodicals and Media Mail offered reduced rates for eligible items, often under $0.50 for publication-range shipments. Buyers should note that customs forms and additional services like tracking or insurance could add to the total cost of mailing internationally.
How Much Did a Book of Stamps Cost in 2018?
A book of 20 Forever stamps commonly sold for $10 in 2018, effectively $0.50 each. Some retailers offered slight discounts on multipacks, while convenience formats like small booklets or rolls could cost slightly more per unit due to packaging and distribution differences. Bulk purchases remained popular among businesses and frequent senders because they reduced per-stamp costs and the frequency of retail trips.
Practical Considerations for Mailing in 2018
- Weight matters: First-Class letters are priced by ounce; a letter over 1 oz incurs additional $0.15 fees per extra ounce.
- Size limits: Standard postcards must meet specific dimensions to qualify for the $0.35 rate; larger cards are priced as flats.
- Plan for international mail: Expect higher rates and longer delivery times; consider tracking and insurance for valuable items.
- Buy in volume when practical: Books of stamps and larger coils often yield a lower effective price per stamp.
- Check for retail promos: Some partners ran periodic promotions that lowered the per-stamp price on books or rolls.
Bottom Line on 2018 Postage Stamp Costs
In 2018, U.S. postage stamp prices remained steady, with a Forever 1-ounce First-Class letter costing $0.50. Additional-ounce fees, postcards, and international rates followed established schedules, and purchasing formats like books or rolls could lower the effective price. For businesses and individuals looking back, understanding these prices helps contextualize historical mailing costs and compare them to current and future rates.
