2026 First Class Postage Rates
First Class rates depend on the shape of your mailpiece (postcard, letter, or large envelope) and its weight. Here are the current 2026 retail prices:
| Mail Type | Starting Price | Notes |
|---|---|---|
| Standard letter (1 oz) | $0.78 | Forever stamp; rectangular, up to 3.5 oz |
| Each additional ounce | +$0.29 | Up to the 3.5 oz letter cap |
| Standard postcard | $0.61 | Rectangular only; oversized postcards pay letter rate |
| Square or oversized envelope | $1.27 | Non-machinable surcharge applies |
| Large envelope / flat (1 oz) | $1.63 | Up to 13 oz; over 11.5 in or thicker than 0.25 in |
| International (1 oz letter) | $1.70 | Global Forever stamp, any country |
USPS has filed a proposal to raise the 1 oz Forever stamp to $0.82 effective July 12, 2026. Forever stamps you already own will still be valid at the new rate.

Delivery Time & Tracking
USPS First Class Mail is the agency's default speed for letters: 1 to 5 business days within the contiguous United States.
- Local (same metro area): typically 1–3 business days
- Same region: 2–4 business days
- Coast-to-coast: 3–5 business days
- Hawaii, Alaska, Puerto Rico, military APO/FPO: 3–5 business days, sometimes longer
Note that these are service standards, not guarantees. If you need a guaranteed delivery date, you have to upgrade to Priority Mail Express — that's the only USPS service with a money-back guarantee.
Does First Class Mail include tracking?
No — not for letters. By default, a First Class letter has no tracking number. To track First Class Mail you have to add a service:
- Certified Mail — adds ~$5.30 and gives you a USPS tracking number plus delivery confirmation. See our Certified Mail guide.
- Registered Mail — slower but the most secure option, with full chain-of-custody tracking.
- Certificate of Mailing — the cheapest add-on (under $2). Proves you mailed on a given date but doesn't give you tracking after that.
If your envelope already has tracking under USPS Ground Advantage, that's a different product — see USPS mail delivery times for the full speed comparison.
Weight & Size Limits
First Class Mail has strict caps on what can ship at the cheap rate.
First Class Limits at a Glance
- • Letters: up to 3.5 oz, max 11.5 in × 6.125 in × 0.25 in thick
- • Postcards: max 6 in × 4.25 in × 0.016 in thick
- • Large envelopes (flats): up to 13 oz, max 15 in × 12 in × 0.75 in
- • Anything heavier than 13 oz: must use Ground Advantage or Priority Mail
If your mailpiece is square (greeting cards, wedding invitations) or rigid, USPS charges a non-machinable surcharge — currently $0.49 over the standard letter rate. Same goes for envelopes with clasps, string ties, or unusual aspect ratios.
For invitations and greeting cards, a square envelope at $1.27 is normal — it's the surcharge, not a mistake. For everything else, check how many stamps you need before you drop the letter.
Where to Buy First Class Postage
You have more options than just the Post Office:
In person
- ✅ USPS Post Office (face value)
- ✅ Grocery stores (Kroger, Safeway, Publix)
- ✅ Drug stores (CVS, Walgreens)
- ✅ Walmart, Target, Costco (often discounted)
- ✅ Most banks sell single books
Online
- ✅ store.usps.com (face value, free shipping over $25)
- ✅ Stamps.com (small commercial discount)
- ✅ Pitney Bowes SendPro
- ⚠️ Avoid third-party Amazon/eBay sellers — counterfeits exist
Counterfeit warning: The USPS Inspection Service has flagged a surge in counterfeit Forever stamps sold at deep discounts on social media and marketplace apps. If a roll of 100 stamps is selling for under $50 (face value would be $78.00), it's almost certainly fake. Counterfeit-stamped mail gets rejected and returned to sender.
Forever Stamps Explained
A Forever stamp is just a First Class 1 oz letter stamp that doesn't expire when rates go up. You buy it at the current rate ($0.78 in 2026) and it stays valid for a 1 oz First Class letter forever — even after USPS raises prices.
Practically that means:
- A Forever stamp bought at $0.55 in 2019 is still valid today for a 1 oz letter.
- If USPS raises the rate to $0.82 in July 2026 as proposed, your stockpile of $0.78 stamps will still cover a full letter — no extra postage required.
- For mail over 1 oz, you stack stamps to hit the new rate (1 oz + 1 extra ounce = $0.78 + $0.29 = $1.07 in 2026).
Forever stamps are also issued for postcards (Postcard Forever, currently $0.61), additional ounces (Additional Ounce Forever, $0.29), and international (Global Forever, $1.70). Each one only works for its specific use case — postcard Forever stamps don't cover a full letter.
First Class vs Other USPS Services
First Class is the cheapest letter option, but not always the fastest or safest.
| Service | Speed | Tracking | Starts At |
|---|---|---|---|
| First Class Mail | 1–5 days | No (letters) | $0.78 |
| Priority Mail | 1–3 days | Yes | $11.65 |
| Priority Mail Express | 1–2 days (guaranteed) | Yes | ~$30 |
| Certified Mail | First Class speed + proof | Yes | $6.08 |
| Ground Advantage | 2–5 days | Yes | ~$5 |
Rule of thumb: send by First Class if it's under 13 oz, not urgent, and doesn't need proof of delivery. Anything else, upgrade. See First Class vs Priority Mail for a deeper cost comparison.
