What are the differences between a Forever Stamp and a Global Stamp? The ultimate comparison guide for 2025.
Whether you’re hesitating at the post office counter, Forever Stamp (for domestic use) and Global Forever Stamp (for international use) are often the two most perplexing options.
On the surface, they’re just different designs, but the “value logic” behind them is completely different, especially when you want to save money while ensuring that your mail isn’t misrouted by USPS.
More common problems include—
Can I send a letter to Europe using a regular national flag forever stamp?
Is it wasteful to put international stamps on domestic letters?
Which one is the most wallet-friendly?
Today we’ll explain it thoroughly and even tell you a real trick to “send international letters for less money”—the kind that most people hardly know.
What is a Forever Stamp? (US domestic standard)
The USPS introduced the Forever Stamp in 2007 to make postage increases less of a hassle. It’s a non-denomination stamp, meaning it doesn’t have a price listed, only “Forever.” Regardless of future postage increases, you can send up
to 1 ounce of First-Class Mail (domestic) by simply affixing one stamp.
1. The core value of Forever Stamp
Current equivalent (2024–2025): Approximately $0.73
Scope of application: All 50 US states + all territories + APO/FPO military addresses
It won’t expire. Even if you bought it 10 years ago, as long as you stick the sticker on it, it’s still worth the current postage.
These USPS stamps are used extensively by ordinary mail carriers and business users and therefore command significant discounts on the secondary market. You can often find discount stamps at 40-50% off in our store, which is why many people are accustomed to stocking up on them.
2. Appearance features of the Forever Stamp
Shapes: Both rectangular and square are available
Patterns: A huge selection
National flag
Love series
Flowers
Holiday themes, character themes… updated almost every year.
Packaging: 20 sheets/100 sheets per roll
What is a Global Forever Stamp? (For international mail only)
The Global Forever Stamp was launched in 2013 with a simple goal:
to make international mail as hassle-free as domestic mail.
1. Core Values
Current equivalent (2024–2025): Approximately $1.65
Applicable to: 190+ countries worldwide
Purpose: To send standard international first-class mail weighing less than 1 ounce.
Whether you ship to the UK, Canada, Japan, France, Hong Kong… the price is the same.
2. Appearance characteristics
Shape: Round (very eye-catching)
Pattern options are limited: chrysanthemums, succulents, globes, etc., making the selection relatively simple.
Packaging: 10 pieces/sheet
The circular shape may seem like just a unique design, but it actually helps USPS sorting machines automatically identify “this is an international shipment,” making it a highly recognizable design.
Five key differences (summarized in a table)
| Comparison Dimensions | Forever Stamp (Domestic) | Global Forever Stamp (International) |
| 1. Current value | $0.73 | $1.65 |
| 2. Shape | Square/Rectangle | round |
| 3. Applicable destinations | Within the United States | 190+ countries worldwide |
| 4. Pattern Selection | So many choices—it’s dazzling! | Limited edition, fixed theme |
| 5. Discount Market | Large quantities of discount stamps are available, with prices up to 50% off. | Discounts are rare, and price reductions are practically nonexistent. |
Why are shape differences so important?
Many people are unaware of this.
USPS does not actually receive “domestic shipments” and “international shipments” in separate boxes initially; they are mixed together.
The circular Global Stamp, combined with a special phosphorescent mark,
allows machines to instantly recognize the letter and direct it directly to the “International Export” section.
If you use a regular forever stamp to send international mail, that’s fine, but
If you stick it in too random a position, the sorting machine might scan it a few more times, which could slightly increase the chance of delay.
Key question: Can they be used interchangeably?
Answer: Yes, but you have to be strategic.
The following two scenarios will help you understand immediately.
Scenario A: Sending international letters using domestic forever stamps (or discount stamps).
Yes.
You just need to do:
You can ship if you affix a Global Stamp with a value of ≥ $1.65.
That is to say:
Domestic Forever Stamp = $0.73
International standard = $1.65
Number of required: 3
Calculate:
$0.73 × 3 = $2.19 (face value)
$2.19 > $1.65 (requirement)
Once USPS sees “sufficient value,” it will ship the item as usual.
Although you “added” an extra $0.54 on paper, if you used a discount stamp (such as a forever stamp you bought at a 50% discount), the actual cost is
The face value of $2.19
Actual cost ≈ $1.08
It’s much cheaper than applying a $1.65 global stamp.
This is why corporate clients and wedding invitation users prefer this combination solution.
Scenario B: Sending domestic letters using Global Stamp
It’s technically feasible but extremely uneconomical.
Domestic mail costs only $0.73
The Global Stamp costs $1.65.
You lose $0.92 for every letter you send.
Unless you absolutely have no forever stamp or the letter is extremely urgent, it is not recommended to do this.
Why is the “Domestic Stamp Set” cheaper than the Global Stamp? (The Ultimate Algorithm)
Let’s look at a real-world example.
You’re preparing to send a wedding invitation to France.
Option 1: Use Global Stamp
Unit price: $1.65
Discount: None
Cost: $1.65
Option 2: Use domestic Forever Stamps (purchase at a discount)
Requires 3 Forever stamps.
Official price: $0.73 × 3 = $2.19
Your actual cost: Assuming you purchased the discount stamp at $0.36 per stamp.
Calculate: $0.36 × 3 = $1.08
Result: You saved $0.57 (about 35%)!
This is why “combined stamps” are very popular among experienced letter writers.
Additional benefit: The envelopes look better.
Global stamps have fewer designs, but the selection of forever stamps in China is almost limitless:
Paste 3 different flowers. It looks like an art postcard
Add 3 Love series stickers → Instantly elevate your wedding invitations
Posting national flags series → Sending a message of affection to relatives and friends overseas
Visually, it does look more “high-end.”
Frequently Asked Questions (FAQ)
Q: Do I need to get 3 forever stamps stamped at the post office counter when sending international letters?
No need.
As long as the weight does not exceed 10 oz and the thickness does not exceed 1/2 inch, you can drop it directly into the blue mailbox.
Q: Can Global Stamp handle overweight emails?
One stamp can only cover 1 oz.
2 oz? You’ll need to pay the difference (e.g., add another forever stamp).
Q: How exactly is the value of a Forever Stamp calculated?
It’s always calculated based on “current postage value.”
If you bought it for $0.55 5 years ago, it’s now worth $0.73.
Summary: Be a smart sender
Both the Forever Stamp and the Global Stamp are practical, but savvy consumers often prefer:
Use the discount forever stamp in combination when sending international letters.
More money
More beautiful
More flexible
Once you understand the core principle of “face value ≥ postage,” you can freely control any domestic and international mailing needs.
