Did you Know? (Jan. 2023) Posted on January 21, 2023January 21, 2023 by Guy Gasser Postage rates are going up again on January 23rd, 2023. A first-class letter up to 1 ounce rises 3 cents to 63 cents, the postcard rate goes up 4 cents to 48 cents, but hey, the additional ounce rate stays the same at 24 cents. At least something didn’t increase! Grow Philatelty - SHARE!!
