About ZIP 04102
ZIP boundaries are postal routes, not tax boundaries.
Maine allows no local sales tax, but prepared food is taxed at 8% and short-term lodging at 9%, which matters in a tourist-heavy Portland. For destination-based sourcing, Maine sellers should confirm the rate by full street address rather than ZIP alone — a single ZIP can cross a city limit or a transit-district boundary, and the rate follows the boundary, not the mail route.
