What changes for people who mail letters
For most everyday 1-ounce domestic letters, you’ll need the stamp value to match the new First-Class rate. If you’re mailing letters using a Forever stamp, you’re generally covered—because a Forever stamp is designed to represent the current price for a 1-ounce First-Class letter, even after rate increases.
What doesn’t change
Forever stamps you already bought will still work after the price increase; the stamp’s “forever” value simply adjusts with the rate.
Quick pricing context
Along with the Forever stamp update, USPS also increased other related postcard/letter prices—for example, domestic postcards move from 61 cents to 65 cents, and international letters/postcards move from $1.70 to $1.75.
Bottom line
If you mail letters today, expect an updated cost basis for 1-ounce First-Class mail—but your existing Forever stamps remain valid for postage on that service level.
