USPS First Class Mail Rates: The Full July 2026 Price Chart

A lot of people slap two Forever stamps on a letter that feels heavy and call it done. That usually wastes money.

USPS first class mail rates changed again on July 12, 2026. A standard 1 ounce letter now costs $0.82 with a Forever stamp, or $0.78 metered. Every ounce after that adds $0.29, not another full stamp.

That one fact is the reason to read this page before you buy more stamps.

Below is the current price list for letters, postcards, large envelopes, the nonmachinable surcharge, and international mail. Every number comes from Notice 123, the official USPS price document. I also cover what changed since January 2026, which is less than most people think.

Current USPS First Class Mail Rates by Weight (July 12, 2026)

Here is the full letter and postcard price list. It comes from the July 12, 2026 edition of Notice 123. These are retail counter prices, not commercial or presort rates.

A letter tops out at 3.5 ounces. Anything heavier moves into large envelope pricing, even if the piece is still folded like a letter.

USPS prices by weight and shape together, not weight alone. A folded letter that hits 4 ounces gets priced as a flat.

Large Envelope (Flat) Rates by Ounce

Large envelopes are often called flats. The category covers anything too big to run through standard letter equipment, like a manila envelope or a catalog. They start heavier and cost more per ounce than a folded letter.

Each step is $0.29 through 8 ounces, then creeps to $0.30 and $0.31 near the top. Large envelopes cap at 13 ounces.

Past 13 ounces, the piece has to ship as a package. Ground Advantage or Priority Mail takes over from there, and our Priority Mail pricing breakdown covers what that costs.

Why a 2 Ounce Letter Is Not Two Stamps

This is the mistake that costs people the most money. A 2 ounce letter costs $1.11. It does not cost $1.64.

USPS charges the base 1 ounce price, then adds $0.29 for the second ounce. That additional ounce charge stays flat no matter how many ounces you stack on.

Doubling up Forever stamps on a 2 ounce letter overpays by 53 cents. If you are unsure what something weighs, a kitchen scale settles it in ten seconds.

Our postage price calculator does the ounce math for you if you would rather skip the table. Enter the weight and it applies the right usps first class mail rates automatically, letter or flat.

There is one fair exception. If you cannot weigh a letter and want it covered no matter what, two Forever stamps work on any letter up to 3 ounces. It is rarely the cheapest way to send it, but honestly, sometimes 53 cents is worth not thinking about it.

The Nonmachinable Surcharge: What Actually Triggers It

The $0.49 nonmachinable surcharge catches more people off guard than any other line on this price list. It stacks on top of the base letter rate. A 1 ounce nonmachinable letter costs $1.31, which is the figure usps.com shows for square and oversized envelopes.

USPS adds the surcharge when a letter cannot run through automated sorting equipment. The triggers are spelled out in DMM 101.1.2.

Square envelopes, clasps, string closures, and rigid or lumpy contents all count. So do pieces too thick or too small for the machines to grip.

A standard rectangular business envelope almost never triggers it. Square wedding invitations do, every time. If the design matters more than 49 cents per envelope, that is a fair trade, but budget for it up front.

International First-Class Mail Rates

A First-Class Mail letter or postcard mailed to another country costs $1.75 as of the July 2026 price list. That is the Global Forever stamp rate. It covers up to 1 ounce to Canada, Mexico, or anywhere else outside the United States.

International letters do not get the same $0.29 per ounce step as domestic mail. Heavier pieces move to their own pricing tiers, and delivery runs well past domestic timeframes.

Our guide to international First-Class Mail breaks down those weight tiers and realistic delivery windows.

What Changed Since January 2026 (And What Did Not)

Here is the part most price roundups get wrong. First-Class Mail rates did not change in January 2026 at all. The Forever stamp stayed at $0.78 straight through that date.

The January 2026 increase only touched Priority Mail, USPS Ground Advantage, Priority Mail Express, and Parcel Select. USPS groups those as Shipping Services, and they move on a different schedule than letters and postcards.

First-Class Mail sits under Mailing Services. Those prices only move under Postal Regulatory Commission price cap rules tied to inflation. That adjustment landed on July 12, 2026.

So a price chart copied in June still looked right. Then July hit, and every usps first class mail rates number moved at once.

The July 12 change raised the Forever stamp four cents, from $0.78 to $0.82. Metered mail moved from $0.74 to $0.78, and postcards rose from $0.61 to $0.65.

The international rate went from $1.70 to $1.75. Additional ounce pricing held flat at $0.29.

Do Forever Stamps Bought Before July 2026 Still Work?

Yes. A Forever stamp bought in 2020, 2023, or last week covers a 1 ounce letter today, no matter what you paid for it. That is the entire point of the Forever design.

You never owe extra postage on a Forever stamp for a standard 1 ounce letter, even after a price increase. The only catch is weight and shape, not the stamp’s purchase date.

A 2 ounce letter still needs $0.29 in extra postage on top of one Forever stamp, price increase or not. People who stocked up on Forever stamps before July 12 locked in the old $0.78 rate for single ounce letters.

That is a real, if modest, savings play. If it were me, I’d buy a few books right before the next increase and stop there. Four cents a stamp is not worth a drawer full of them.

Not sure what a book or a roll runs right now? Our current stamp price guide keeps that table updated. The stamp calculator tells you how many stamps to stick on a piece of any weight.

Why Some Rate Calculators Show the Wrong Number

Third party shipping tools and browser extensions sometimes lag behind an official price change by days or weeks. A seller checking a cached calculator right after July 12, 2026 might still see $0.78 listed as the Forever stamp price.

That gap causes real confusion among small sellers who print postage in bulk through platforms like eBay or Etsy. The fix is to cross check any number against Notice 123 or usps.com itself.

The gap usually closes within a week or two as tools sync with the new usps first class mail rates.

How First-Class Mail Compares to Other USPS Services

First-Class Mail is the cheapest USPS option for letters and small flats, but it comes with tradeoffs. The table below shows where it sits against the next options up.

No tracking number comes with a stamped letter or postcard. That is the tradeoff for the low price.

If you need proof of delivery or a date guarantee, or the piece weighs over 13 ounces, Priority Mail becomes the better option. For how the service itself works rather than what it costs, see our First-Class Mail overview. For real timeframes by distance, the First-Class Mail delivery time guide has you covered.

What Happens If You Mail a Letter Without Enough Postage

Underpaid mail does not vanish. USPS usually catches it at the sorting facility. It either returns the piece to the sender or delivers it with a postage due notice attached.

The recipient can end up owing the shortfall. That is not a great surprise to hand a friend or a customer.

A quick weight check before you seal the envelope avoids it.

If you run a small shop and mail dozens of envelopes a week, a cheap digital postal scale pays for itself fast. Overpaying by 29 cents on 50 envelopes a week is about $750 a year.

Bottom Line

As of July 12, 2026, usps first class mail rates start at $0.82 for a 1 ounce stamped letter and $0.78 metered. Postcards run $0.65, and each additional ounce past the first adds $0.29. Large envelopes run from $1.69 up to $5.24 at 13 ounces.

The nonmachinable surcharge adds $0.49 on top of the base rate, and international letters cost $1.75 flat. Nothing changed in January 2026. The real jump happened this July.

Weigh your mail before guessing at stamps. The ounce math rarely lines up with round numbers of Forever stamps.
