Key facts about postcard stamp pricing
The most reliable, evergreen guidance on U.S. postcard stamps is straightforward: a single First-Class Mail postcard stamp currently costs $0.66. This base price has been stable since 2023, after the rate increased from $0.63 in January 2023 and remained steady through 2025. Postcards must meet size, weight, and shape rules to qualify for this rate. Additional ounces or nonmachinable features may add extra postage. The following sections explain who sets these prices, how to buy stamps, and how mailing choices affect cost.
Understanding postcard mail categories
Postcard pricing depends on which class and service you use. The two main domestic options are First-Class Mail and Marketing Mail. First-Class Mail is typically faster and includes tracking for most pieces; Marketing Mail is lower priced but slower and less tracking-intensive. Both have specific design and weight requirements that change the final price. Knowing which service fits your needs helps you choose the right stamp or metered rate and avoid returned mail or extra fees.
First-Class Mail postcards
First-Class Mail postcards follow strict size and weight rules. If a piece is rectangular, rigid, and nonmachinable, higher prices apply. Standard postcard rules include being at least 3.5 inches by 5 inches and no more than 4.25 inches by 6 inches. Weight must be 1 ounce or less. Meeting these rules lets you use the base postcard price. Missing these requirements can shift the piece into letter pricing, which costs more.
Marketing Mail postcards
Marketing Mail postcards are a lower-cost option for larger mailings. Postcards must still be rectangular and within size limits, but weight and design rules differ. You generally need enough volume to qualify for automation prices. While base Marketing Mail postcard prices are lower than First-Class, you cannot use a single stamp for metered or discounted batches; you must use postage meters or indicia. This distinction matters for high-volume mailers.

How to buy postcard stamps in 2025
You have several options to buy postcard stamps. Each method affects convenience, availability, and sometimes price. Choose the approach that matches how frequently you mail postcards and whether you prefer physical or digital management of postage.
- Post office counter: Available in most locations and useful when you need stamps immediately. Staff can help verify current pricing and acceptable forms of payment.
- Retail partners: Many grocery stores, pharmacies, and big-box retailers sell stamps. Confirm they sell Forever stamps if you want long-term usability.
- Online and mobile: The USPS website and mobile app allow you to buy and store stamps digitally. You also can print Priority Mail labels with integrated postage if you ship packages or larger items.
- Metered mail: For businesses, postage meters offer discounts off single-stamp prices. This is common for high-volume mailers who want to manage costs and simplify postage accounting.
What adds cost to a postcard mailing
Several details can push a postcard above the base rate. Extra ounces, nonstandard shapes, and nonmachinable features such as foil or thick paper often cause additional charges. Return service, insurance, and special handling for fragile items also add to the total price. If you are unsure, take your postcard to a counter or call customer support to avoid surprises at shipment time.
International postcard considerations
Sending postcards abroad uses a separate price category. As of the latest standing rates, a U.S. postcard to most countries typically costs above the domestic First-Class price, depending on destination region. International rules about size, content, and customs forms can also affect delivery time and required postage. Always check current international rates before mailing to avoid delays or extra fees at the border.
Design and content rules to keep costs predictable
Following design and content rules helps your postcard stay in the intended price tier. Keep your piece rectangular, under 1 ounce, and within dimensional limits. Avoid nonmachinable embellishments unless you budget for higher postage. If you plan to use a stamp, make sure the value matches or exceeds the current First-Class postcard price to prevent returns or additional handling fees.
Bottom line on postcard stamp pricing
As of the most recent standing rates, a First-Class Mail postcard stamp is $0.66. This reflects increases that occurred in 2023 and 2024, and it has remained steady into 2025. Postcard rules around size, weight, and shape remain important; meeting them helps you avoid higher letter rates. By understanding when prices changed, how to buy stamps, and what adds cost, you can plan mailings confidently and accurately.
