Appropriate use and limits

Street, city, state, and ZIP Code come from checkable public non-residential locations; names, emails, and test phone numbers are synthetic. Results do not represent a real resident and are not USPS delivery-point verified. Do not use them for shipping, payments, identity checks, credit, or bypassing platform rules.

State and local tax rules may vary by locality and transaction type.
