Sending a postcard is one of those classic, thoughtful gestures that never fade. Whether you’re jotting a quick note to loved ones while traveling, adding a personal touch to your business marketing, or simply brightening someone’s day, postcards are a meaningful and cost-effective way to connect.
But before you drop one in the mailbox, there is one key detail you need to get right, postcard stamps. With different mailing options, changing rates, and various stamp types to choose from, it is easy to get a little confused. What kind of stamp do you need? Where can you buy it? And how much does it cost to send a postcard today? This guide covers stamp types, pricing, where to buy them, and USPS mailing tips.
What is a Postcard?
The USPS defines a postcard as a rectangular piece of cardstock or thick paper designed for mailing without an envelope. However, not all small cards qualify. To meet postcard mailing standards and receive the lower postage rate, the card must have dimensions between 3.5″ x 5″ and 4.25″ x 6″. Anything larger or non-rectangular is classified and priced as a letter.
| Mail Type | Message Visibility | Purpose | Uses |
|---|---|---|---|
| Postcard | Visible on the back | Short and casual messages | Travel notes, marketing mailers |
| Letter | Hidden in the envelope | Formal communication | Business letters, personal correspondence |
| Greeting Card | Hidden, often decorative inside | Celebratory messages for special events | Birthdays, holidays, thank-you notes |
Here are some of the most common uses of postcards:
- Travelers use postcards to share snapshots of their journeys, beach views, iconic landmarks, or cultural moments with their friends and family.
- Businesses rely on postcards for direct mail marketing because they are affordable, highly visible (no envelope needed), and often generate better engagement.
- Individuals send postcards for personal messages like quick greetings, thank-you notes, holiday wishes, or party invitations without the cost of a full letter.
How Much is a Postcard Stamp?
The postcard stamp price for standard domestic postcards is $0.56. This rate applies only if the postcard meets USPS guidelines for size and thickness:
- Minimum: 3.5″ x 5″
- Maximum: 4.25″ x 6″
- Thickness: Between 0.007″ and 0.016″
Any deviation from these standards can change the postage required. Let’s find how postcard stamps cost compares to First-Class Mail:
- Postcard stamp cost: $0.56
- First-Class Mail (letter) stamp: $0.66
That’s a $0.10 difference per piece, which can add up significantly, especially for businesses or organizations sending out postcards in bulk. Postcard postage stamps offer a more economical solution when mailing standard-sized cards.
Also, if your postcard exceeds USPS’s maximum dimensions, it will be considered and mailed as a letter. In this case, you’ll need to use a Forever® stamp, increasing the cost of a postcard stamp to $0.66. This highlights the importance of verifying postcard dimensions before mailing to ensure you are paying the correct rate.
Where to Buy Postcard Stamps?
Postcard stamps are widely available at a variety of locations, making it easy for anyone to purchase them.
Post Offices
The most traditional place to buy postcard stamps is directly at your local USPS post office. This option allows you to purchase stamps in person and speak with a postal worker if you have any questions.
USPS Website
You can also purchase postcard stamps from the official USPS website. This is convenient for people who prefer to shop online and have stamps delivered to their door.
Retail Stores (via Stamps to Go® Program)
USPS partners with retail stores across the country to sell stamps through their Stamps to Go® program. This includes many supermarkets, drugstores, and convenience stores.
Online Services
For frequent mailers, several online services offer the ability to buy postage online and print it at home. This is especially useful for businesses or individuals who send large volumes of mail.
USPS Kiosks
Many post offices have self-service kiosks where you can purchase stamps and postage without waiting in line.
Types of Stamps You Can Use for Postcards
While postcard-specific stamps are designed and priced for mailing postcards, here are the types of stamps you can choose from:
Postcard Stamps (Specifically Designed and Priced for Postcards)
These stamps are specifically priced for postcards, costing $0.56 for domestic use. They are the most straightforward and cost-effective choice for mailing postcards in the U.S.
Forever Stamps
While Forever Stamps are intended for use on letters, they can also be used on postcards. However, Forever Stamps cost more than the postcard-specific stamp, as they are priced for First-Class Mail letters. Therefore, using a Forever Stamp on a postcard would cost $0.66 instead of the standard $0.56.
Global Forever® Stamps
If you are sending a postcard internationally, Global Forever® Stamps are the best option. These stamps are priced to mail a postcard or letter anywhere in the world.
Understanding postcard stamps vs regular stamps helps you choose the most affordable option every time. This table below outlines which type of stamp to use based on mailing requirements:
| Mailing Scenario | Use this Stamp |
|---|---|
| Standard U.S. postcard | Postcard stamp |
| Oversized postcard or letter | Forever® stamp |
| International postcard | Global Forever® stamp |
Sending Postcards Internationally
When sending postcards overseas, you’ll need to use Global Forever® Stamps to ensure your postcard meets the international postage rate. These stamps are priced at $1.50 and are good for mailing postcards to any destination worldwide, regardless of the weight or size of the postcard.
International postcard dimensions are generally similar to domestic requirements, but it is important to always check the specific postal guidelines of the destination country. Some countries may have different rules regarding the acceptable size of postcards.
Postcards sent internationally have different rates depending on the destination.

Design & Writing Guidelines for Postcards
Before you drop your postcard in the mail, it is important to follow a few basic design and formatting rules to ensure it is processed correctly by USPS.
Where to Place the Stamp
Place your postcard stamp in the upper-right corner on the back side of the postcard (the address side). This is the standard position recognized by USPS and ensures your card moves efficiently through automated processing.
How to Format the Back
USPS prefers a clear layout to avoid delays. Keeping these areas separate helps prevent interference with postal barcodes and scanning systems.
- Right-hand side: Reserved for the recipient’s address only.
- Left-hand side: This is where you can write your personal message.
Make It USPS-Friendly: Readability Tips
To ensure your postcard is properly scanned and delivered:
- Use dark, non-smearing ink (black is best) for both your message and address.
- Avoid cursive or overly stylized handwriting, print clearly whenever possible.
- Leave space around the barcode and address area, no stickers, decorations, or extra writing.
Tips for Mailing Postcards
A well-prepared postcard can arrive quickly and in perfect condition. Follow these simple, proactive tips to make sure your message gets where it needs to go, clearly and on time:
- Skip the lamination: Let your postcard travel light. Laminated surfaces can confuse USPS scanners and slow down processing. Stick with standard finishes to keep your postcard moving smoothly through the mail.
- Keep barcodes and addresses clear: Avoid placing stickers or decorations over the address or barcode area. A clean layout helps postal machines read and route your postcard without errors or delays.
- Use waterproof ink and write clearly: Your message should always stay legible. Choose waterproof ink and print neatly to ensure your words arrive just as you wrote them.
- Plan around mailing times: Local mail often arrives within a few days, while national deliveries may take a bit longer. Factoring in time helps your message land right when it matters most.
