USPS Files January 2027 Prices: 5.9% Increase Plus an 11% Fuel Surcharge
USPS has put numbers on its 2027 package prices. On November 12, 2026, the Postal Service filed notice with the Postal Regulatory Commission (PRC) for price changes taking effect January 17, 2027: an average 5.9% increase on domestic shipping plus a fuel surcharge of 11%. This is a follow-up to our October 28 article on the planned USPS fuel surcharge, with the new details sellers were waiting for.
What USPS filed
According to the USPS announcement (Nov 12, 2026), approved by the USPS Board of Governors that week:
- Domestic prices +5.9% on average for Priority Mail, Priority Mail Express, USPS Ground Advantage and Parcel Select, effective January 17, 2027.
- 11% fuel surcharge. The 8% "transportation-related" increase implemented in April 2026 becomes a permanent 8% fuel surcharge, "plus an additional 3 percent given the recent further elevation of fuel prices for a total of 11 percent."
- Review in July 2027. The surcharge "will not impact international products at this time" and will be reevaluated in July 2027 based on fuel prices in the first half of 2027.
- International prices +7.9% on average for Priority Mail Express International, Priority Mail International, First-Class Package International Service and International Priority Airmail.
- Competitive PO Box prices are not changing in January. The PRC will review the changes before they take effect (Docket No. CP2027-1).
Spectrum News (Nov 13) reported the same figures. According to Supply Chain Dive (Nov 13), the 5.9% average "matches the averages of FedEx and UPS' upcoming rate hikes." It also reports, citing the PRC filing, that the surcharge will be fixed in January but USPS "eventually intends to adjust the rate on a weekly basis" using EIA fuel prices, with the dynamic surcharge to be authorized "later in 2027."
Sample January 2027 Ground Advantage prices
USPS has already posted the proposed price files on Postal Explorer. These are commercial Ground Advantage base prices from the January 2027 file (dated Nov 12, 2026), with our calculation of the price after the 11% surcharge (Calculation: base × 1.11, rounded; USPS's own rounding may differ slightly):
| Weight | Zone 1 | Zone 5 | Zone 8 |
|---|---|---|---|
| 4 oz, base | $6.90 | $7.61 | $8.27 |
| 4 oz, with 11% surcharge | ≈ $7.66 | ≈ $8.45 | ≈ $9.18 |
| 1 lb, base | $7.97 | $8.77 | $10.18 |
| 1 lb, with 11% surcharge | ≈ $8.85 | ≈ $9.73 | ≈ $11.30 |
| 5 lb, base | $9.61 | $13.23 | $18.30 |
| 5 lb, with 11% surcharge | ≈ $10.67 | ≈ $14.69 | ≈ $20.31 |
The proposed fuel surcharge tables in the same file list 11% for both the diesel-based and jet-fuel-based surcharges.
The financial background
Supply Chain Dive reports that USPS posted a $6.5 billion net loss in fiscal 2026, while shipping and packages revenue rose 5.1% year over year despite a 5.3% volume decline. In other words, USPS is earning more per package, and the 2027 changes continue that strategy.
What it means for sellers (our analysis)
- Compare totals, not base rates. The January base prices look close to today's because the 8% temporary increase moves out of the base and into the surcharge. Your actual cost is base plus 11%.
- USPS is no longer the "no fuel surcharge" carrier. With UPS and FedEx also raising rates about 5.9% on average, the gap between carriers now depends more on surcharges, zones and your negotiated discounts.
- Budget for change in mid-2027. The 11% is reviewed in July and a weekly surcharge is planned later, so treat 11% as a starting point.
- Cross-border shippers using USPS international services face a 7.9% average increase, but no fuel surcharge for now.
Checklist before January 17
- Re-rate your top 20 SKUs by weight and zone using the January price file plus 11%.
- Update shipping templates on Amazon, Walmart, TikTok Shop and your own site so customer-paid shipping still covers cost.
- Check package dimensions and weight; see our Ground Advantage guide for pricing rules.
- Ask your label provider when the new rates and surcharge will appear in your software.
- Compare USPS against regional carriers for zones 5–8, where the dollar increase is largest.
