USPS prices domestic parcels by service tier, weight, and zone. The zone (1-9) is derived from the distance between the origin SCF (the first 3 digits of the origin ZIP, which identifies a Sectional Center Facility) and the destination SCF. Zone 1 is the same SCF area; zone 8 is transcontinental; zone 9 is non-contiguous (Alaska, Hawaii, US territories). The four main service tiers are Ground Advantage (2-5 day economy, up to 70 lb, replaced First-Class Package over 1 lb and Retail Ground in 2023), Priority Mail (1-3 days, with free flat-rate boxes), Priority Mail Express (1-2 days, money-back guarantee), and First-Class Package (sub-16 oz envelopes and lightweight items only). Worked example: a 2 lb package from Los Angeles (90001) to New York City (10001) is roughly zone 8. At 2026 retail, Ground Advantage runs about $11-13, Priority Mail around $18-22, and Priority Mail Express around $50-60. First-Class Package does not apply because the parcel exceeds 16 oz. If you ship more than a few packages a month, do not pay retail - platforms like Pirate Ship, Shippo, and Stamps.com unlock commercial pricing 30-50% below counter rates.
