About this project

zipseek.us is a static ZIP ↔ City/State lookup tool. It is hosted on AWS (S3 + CloudFront) and runs entirely in your browser by loading a local ZIP dataset and filtering it client-side.

Permitted use

• Private, non-commercial use is allowed.
• Commercial use is not permitted without explicit permission from the project owner.
• You may not present this site (or copies/derivatives) as your own commercial product or service.

Privacy

• No user accounts.
• No in-app tracking scripts or analytics are intentionally used.
• Your searches are performed locally in your browser; the site does not provide a lookup API.
• Like most websites, AWS/CloudFront may log standard request metadata (e.g., IP address, user agent) as part of normal web delivery.
