Buy With Confidence: What You Need to Know First
Before you compare sellers, three facts shape every buying decision:
- Current postcard postage: A Postcard Forever stamp has a 65-cent postage value for a qualifying domestic postcard. An ordinary letter-rate Forever stamp has an 82-cent postage value.
- Forever validity: A Forever stamp is accepted for any standard domestic 1-ounce First-Class letter or postcard, regardless of when it was purchased or what was paid.
- 2026 price increase: USPS has filed to raise the Forever stamp price to $0.82 effective July 12, 2026. Shoppers with real mailing needs — invitations, invoices, seasonal postcards — can buy at $0.78 now and use those stamps well beyond the increase.
Authentic USPS stamps carry “Forever” and “USA” text, clean perforations, and consistent color and print quality. A quick visual inspection when your order arrives is usually all it takes to confirm you received genuine postage.
About This Stamp: USPS Postcard Stamps
When shoppers search for “USPS postcard stamps,” they are typically looking for valid postage to send standard postcards through the U.S. mail. USPS offers two practical options, and understanding the difference helps you choose the right stamp for your needs.
Option 1: Forever Stamps (Most Versatile)
Forever stamps cost $0.78 each and are accepted on postcards, letters, greeting cards, invoices, and other standard First-Class mail up to 1 ounce. They are the most versatile choice because their mailing value is permanent — a stamp purchased at today’s rate stays valid after any future price change. USPS releases dozens of Forever stamp designs every year, from patriotic themes and nature photography to holiday art, pop-culture commemoratives, and love-themed designs perfect for wedding mailings.
Option 2: Postcard-Rate Stamps (Lowest Cost per Piece)
USPS also sells stamps denominated at the current postcard rate of $0.65. These stamps cost less per piece, but they are designated for postcards only. If you send large volumes of standard postcards — event announcements, business promotions, tourism mailers — the postcard-rate stamp saves $0.22 per piece compared with a Forever stamp. Keep in mind, however, that if the postcard rate increases in the future, you would need additional postage to make up the difference. Forever stamps remove that concern entirely.
Which Should You Choose?
| Factor | Forever Stamp ($0.78) | Postcard-Rate Stamp ($0.56) |
|---|---|---|
| Works on postcards | Yes | Yes |
| Works on letters & cards | Yes | No — extra postage needed |
| Rate-proof after price increases | Yes — always valid | No — may need top-up postage |
| Best for | Mixed mailing needs, flexibility | High-volume postcard-only mailings |
For most households and small businesses, Forever stamps are the simpler buy. You never have to worry about whether you attached the right stamp, and you can use the same roll or book for postcards, letters, and cards interchangeably.
Where to Buy USPS Postcard Stamps: Channel Comparison
You are not limited to waiting in line at the post office. Here is how the main buying channels compare on price, convenience, design selection, and volume options.
| Channel | Typical Price (per Forever stamp) | Convenience | Design Selection |
|---|---|---|---|
| USPS.com / Post Office | $0.82 (face value) | In-store wait or online order with shipping | Full current catalog |
| Grocery & Pharmacy Counters | $0.82 (face value) | Pick up during regular shopping trips | Limited — usually current Forever flag or seasonal |
| Big-Box Retailers | $0.82 (face value) | Available at checkout or customer service desk | Minimal selection |
| Costco | ~$0.7775/stamp (roll of 100 ≈ $77.75) | Requires membership; bulk roll only | One or two designs at a time |
| Independent Online Sellers | from an independent retailer — often 10–15% off | Ship to your door; no membership needed | Broader selection; design requests often possible |
How differently priced Stamps Work
When a business closes, downsizes, or runs a mail surplus, its unused stamp inventory can be resold through legitimate channels. Those stamps are still valid USPS postage — the face value does not change. Independent sellers inspect and sort this inventory, then offer it to shoppers below the price you would pay at the post office. For postcard senders who need 50, 100, or several hundred stamps, the cost planning add up quickly.
How Many Postcard Stamps Do You Need?
Matching your order to your actual mailing needs avoids both waste and repeat trips. Here are common scenarios and the quantities that fit them.
- Everyday household mail (5–15 pieces/month): A book of 20 lasts well over a month and fits in a drawer or planner.
- Holiday cards or seasonal greetings (25–75 pieces): One roll of 100 covers most personal mailing lists with extras left over.
- Wedding save-the-dates and invitations (50–200 pieces): Order one to two rolls and keep any surplus for thank-you cards and reply envelopes.
- Small-business postcards, invoices, or customer notes (100–500 pieces/quarter): A multi-roll order gives the best per-stamp value and reduces reordering frequency.
- Event planners or nonprofits (500+ pieces): Buying in volume from an independent seller can yield cost planning of 10–15% off face value versus buying at the post office counter.
Remember: a standard rectangular postcard measuring 3½ × 5 inches up to 4¼ × 6 inches and weighing 1 ounce or less requires one stamp. Oversized, square, rigid, or heavy postcards may need additional postage.
Choosing a Postcard Stamp Design
USPS releases new stamp designs throughout the year, and the right design can complement the tone of your mailing. Here are popular categories for postcard senders:
- Love & wedding themes: Hearts, floral illustrations, and romantic typography — ideal for save-the-dates, engagement announcements, and Valentine’s Day mailings.
- Holiday & seasonal art: Winter scenes, autumn leaves, patriotic flags, and springtime florals for seasonal greetings and business holiday cards.
- Nature & wildlife: Landscapes, birds, flowers, and ocean scenes that pair well with travel postcards or outdoor-event invitations.
- Pop-culture commemoratives: Music legends, classic toys, and iconic figures that add personality to personal and promotional mail.
- Classic flag designs: A timeless option for business correspondence, invoices, and formal mailings.
If you are ordering from an independent online seller, you can often request specific designs or themes. This is especially helpful for event planners and small businesses who want stamps that match their branding or mailing aesthetic.
Postcard Mailing Tips Worth Knowing
- Standard postcard size: USPS defines a postcard as a rectangular card between 3½ × 5 inches (minimum) and 4¼ × 6 inches (maximum), with a thickness between 0.007 and 0.016 inches.
- Non-machinable surcharge: Square postcards, rigid cards, or those with clasps, strings, or protruding elements may incur a non-machinable surcharge. Using a Forever stamp covers the base postage, but a surcharge requires additional stamps or postage.
- International postcards: A single Forever stamp does not cover international mail. International postcards currently require $1.65 in postage (the First-Class Mail International letter rate for 1 oz or less).
- Address placement: USPS guidelines call for the delivery address on the right half of the address side, with postage in the upper-right corner.
Frequently Asked Questions
Can I use a Forever stamp on a postcard?
Yes. A Forever stamp covers the postage for any standard domestic postcard or 1-ounce First-Class letter. It is the most versatile option if you send a mix of mail types.
How much cheaper is a postcard-rate stamp?
The current postcard-rate stamp costs $0.65, which is $0.17 less than the $0.82 ordinary Forever stamp. However, postcard-rate stamps are valid only for postcards and lose their full value if the postcard rate increases.
Are differently priced stamps from online sellers genuine?
Reputable independent sellers source unused, valid USPS postage from surplus inventories, liquidations, and closed businesses. All stamps should arrive in unused condition with clean perforations and consistent print quality. If anything looks off — smudged ink, missing text, uneven perforations — contact the seller before using the stamps.
Do postcard stamps expire?
Forever stamps do not expire. Their mailing value adjusts automatically with each rate change. Denominated stamps (like the $0.56 postcard-rate stamp) keep their printed value but may need supplemental postage if the rate increases beyond the denomination.
How many stamps do I need for a square postcard?
Square postcards are considered non-machinable by USPS. In addition to the base postcard or letter postage, a non-machinable surcharge applies. Check the current USPS price list for the exact surcharge, or use a Forever stamp plus an additional stamp to cover the difference.
