New 2025 shipping rates—and our lowest “Best rate” labels yet.

Open to learn more.

Hi blrnz.ppd, USPS increased its shipping prices on July 13*. As a result, Mercari's prepaid USPS label rates will rise by 2% on average starting July 28, 2025—still well below the carrier's published increases, including a 7.1% hike for USPS retail rates for Ground Advantage®. View the updated rates here. Want to save more? Our new Best rate labels can lower your shipping costs even more when your package meets size limits.

The good news:

Starting July 28: Save more with Best rate labels. Add package dimension info when you list to unlock lower Best rate pricing — an average of 6% cheaper than our current standard rates. If your package meets size limits (1 cu ft / 22″ longest side), Best rates apply. If it's larger, standard rates apply, and we'll price by dimensional weight for a more accurate label. See how it works here.

Fashion ships for less. Our new $7.97 flat rate — up to 5 lb when size limits are met — gives sellers one of the most competitive options for shipping fashion items. Mercari still beats retail rates. Mercari prepaid labels still offer an average of 40% savings** compared to retail carrier rates. Plus, every label offers up to $200 in Shipping Protection and $20 for First-Class Envelope.

Key dates

July 28, 2025 — New rates apply to all new (or edited) listings. August 22, 2025 — Existing listings update automatically (no action needed).

Tips to avoid extra fees

Enter your package dimensions to unlock Best rate pricing and help selecting the correct label. Stay within label limits — if your package is too heavy or too large for the selected label, Mercari will adjust the fee after shipping based on size and weight differential provided by the carrier.

Affordable, predictable shipping helps everyone sell more. Thanks for being part of the Mercari community! - Team Mercari
