It currently costs 61 cents to mail a standard First‑Class postcard within the United States in early 2026. International postcards from the U.S. start at about 1.70 dollars per card.

Quick Scoop

  • A regular U.S. postcard stamp: 0.61 dollars.
  • This rate was increased in July 2025 and is still in effect into 2026.
  • International postcards sent from the U.S.: from 1.70 dollars per card.
  • These prices apply to standard‑size postcards that meet USPS size and thickness rules.

If you’re planning a big postcard campaign, bulk/marketing mail and presort discounts can bring your postage down into the 0.35–0.42 dollars per piece range, but they require volume and proper preparation.

In other words, for a single vacation postcard home from the U.S., you’re usually looking at just over half a dollar in postage—still one of the cheapest ways to send real mail.

TL;DR: For a standard postcard in the U.S., budget 0.61 dollars domestic and 1.70 dollars international for postage as of early 2026.
