USPS Shipping Rates Rate Chart by Weight + Service Tiers

USPS shipping rates in 2026 scale from a few dollars for the lightest Ground Advantage package up to the heaviest 70-pound Priority Mail parcels — but the rates most small-business and ecommerce sellers actually pay are 60-89% lower than retail through commercial pricing platforms. This guide is the complete 2026 USPS shipping rates reference: a rate structure by weight across Ground Advantage, Priority Mail, and Priority Mail Express; the full service-tier breakdown (including Flat Rate, First-Class Mail, and Media Mail); and a clear answer to how businesses pay less without committing to monthly software fees.

Rates reflect USPS Notice 123 effective January 19, 2026. USPS publishes retail rates (paid at the Post Office counter) and commercial-base rates (paid through approved shipping platforms). Final rates depend on origin and destination ZIP codes (Zones 1-9), package dimensions, and any extra services. For exact-ZIP pricing on a specific package, use the USPS Price Calculator linked from the USPS Ship hub or the USPS Business Prices page.

USPS Shipping Rates by Weight Chart (2026)

The USPS shipping rates by weight chart below shows retail starting prices for the three domestic package services across a representative range of weights, Zones 1-4 (regional and near-regional). For Zone 5-9 (cross-country) pricing, add roughly 15-50% depending on weight and service. Priority Mail Express prices reflect the standard retail tier; Sunday and holiday delivery surcharges apply separately.

Two patterns worth noting in this chart: (1) Ground Advantage dominates on price for every weight class — it replaced First-Class Package Service and Retail Ground in 2023 and is now USPS’s flagship economy package option; (2) Priority Mail Express has a steep entry price because the base rate reflects guaranteed 1-2 day delivery rather than weight-based metering. For light packages where speed matters less, Ground Advantage’s 3-5 business day window typically wins on rate-per-pound. For a deeper look at picking between the two, see how to estimate USPS shipping rates for ecommerce sellers.

USPS Service Tiers and What They Cost in 2026

USPS offers six domestic shipping services that small businesses and ecommerce sellers actually use day-to-day. Each has a distinct rate structure, delivery window, and best-fit use case. Pricing below is retail (commercial pricing is lower — see the small-business section).

USPS Ground Advantage

Ground Advantage is USPS’s economy package service for packages under 70 pounds, with 3-5 business day delivery to most U.S. addresses. Retail rates scale with weight and zone and start low for the lightest packages. Ground Advantage includes USD 100 of insurance and USPS Tracking at no extra charge. It is the cheapest USPS option for most package weights below 5 pounds and remains competitive against UPS Ground and FedEx Ground for ecommerce shipping. Service details: USPS Ground Advantage.

USPS Priority Mail

Priority Mail is the standard 1-3 business day USPS service, available in both weight-based and Flat Rate options. Retail Priority Mail rates start low for a light package and include USD 100 of insurance plus tracking. Priority Mail is the workhorse for small businesses shipping 1-10 pound packages where 1-3 day delivery is a customer expectation. Service details: USPS Priority Mail. For Priority versus Ground Advantage trade-offs, see Priority Mail vs Ground Advantage.

USPS Priority Mail Express

Priority Mail Express is USPS’s guaranteed overnight option (1-2 day delivery, money-back guarantee if missed). Retail rates start well above the economy services for an Express envelope and include USD 100 of insurance. Express is the only USPS service with a delivery guarantee, which is why the base rate is materially higher than Priority Mail. For documents and high-value small parcels with tight delivery deadlines, Express is the USPS option; for everything else, Priority Mail is typically the better economy-speed trade-off. Service details: USPS Priority Mail Express.

USPS Priority Mail Flat Rate Boxes and Envelopes

Flat Rate packaging ignores weight and zone — you pay the same rate to ship anywhere in the U.S. as long as it fits in the box and stays under 70 pounds. 2026 retail Flat Rate pricing:

Flat Rate beats weight-based pricing whenever the package is heavy AND going far. For a 15-pound package from California to Maine, the Medium Flat Rate Box undercuts weight-based Priority Mail for the same weight at Zone 8 by more than half. For lighter packages or short-distance shipments, weight-based Ground Advantage or Priority Mail almost always wins.

USPS First-Class Mail (Letters and Large Envelopes)

First-Class Mail covers letters, postcards, and large envelopes (flats) up to 13 ounces. The First-Class formats:

• First-Class letter (1 oz, Forever stamp)
• First-Class large envelope / flat (1 oz)
• Postcard
• Metered letter rate (commercial accounts)

First-Class Mail is for paper documents, invitations, and very thin lightweight items. For anything packaged (boxes, padded mailers, anything more than a flat envelope), Ground Advantage is the correct service — First-Class Package Service was discontinued and rolled into Ground Advantage in 2023. Service details: USPS First-Class Mail. When you need legal proof of mailing and delivery for a First-Class letter, add certified mail at the counter or online.

USPS Media Mail

Media Mail is USPS’s discounted rate for educational materials — books, films, sheet music, printed test materials, and bound transcripts. Retail Media Mail rates are based on a first-pound rate plus a per-additional-pound charge up to 70 pounds. Media Mail is materially cheaper than Ground Advantage for heavy books and educational goods, but the eligible-content restrictions are strict (no commercial advertising, no general merchandise) and delivery runs 2-8 business days. Service details: USPS Media Mail.

International Rate Options

USPS offers four primary international services in 2026: Priority Mail Express International (3-5 business day delivery, money-back guarantee to select countries), Priority Mail International (6-10 business days), First-Class Package International Service (varies by destination, up to several weeks), and Global Express Guaranteed (1-3 business days, USPS’s premium international tier). International retail rates start with a Priority Mail International Flat Rate Envelope and climb sharply with weight and country group. A small parcel under 4 pounds to Canada or another Group 1 destination (Mexico) prices well below Western Europe, while Group 4-7 destinations (Asia, Oceania) run significantly higher.

Small Business USPS Shipping Rates: How to Get Discounted Pricing

Every retail rate quoted above is the price you pay at the Post Office counter. Almost no business actually pays retail. USPS offers two pricing tiers for businesses that ship more than a handful of packages a month: commercial-base pricing (available to any business through a USPS-approved shipping platform, no minimum volume) and commercial-plus pricing (negotiated for high-volume shippers, typically requires 50,000+ packages annually).

Commercial-base rates run 25-45% below retail across Priority Mail and Ground Advantage. For ecommerce sellers shipping 10-100 packages a week, commercial-base is the default — and access does not require a monthly software subscription, a contract minimum, or volume commitments.

How ParcelPath Gets You USPS Commercial Rates

ParcelPath is a pay-as-you-go shipping platform that gives small businesses and individual sellers direct access to USPS commercial pricing — no monthly fee, no contract, no minimum volume. Print labels at commercial-base rates that work out to 60-89% off retail on common ecommerce shipments. Sample real-world savings:

• 2 lb Priority Mail to Zone 4: about 31% off retail with commercial-base pricing
• 5 lb Priority Mail to Zone 8: about 37% off retail with commercial-base pricing
• 10 lb Ground Advantage to Zone 6: about 33% off retail with commercial-base pricing

Beyond rate discounts, ParcelPath includes the operational details small businesses need: tracking, USD 100 insurance built into Priority Mail and Ground Advantage labels, free package pickup scheduling, and the ability to print one-off labels without a recurring subscription.

Start Shipping at USPS Commercial Rates

Retail USPS shipping rates are a starting point, not a final price. Any small business shipping more than a few packages a month should be on commercial-base pricing — and there is no longer a contract, monthly fee, or volume minimum standing between a small seller and those rates. Create a free ParcelPath account to start printing USPS labels at commercial pricing, or use the USPS shipping rates calculator to price a specific shipment at commercial rates before you commit.
