How We Make Money

ZipCheckup is a free service. We earn revenue when visitors call phone numbers displayed on our site and connect with local service providers (plumbers, water treatment specialists, etc.). This is called “pay-per-call” advertising.

What This Means for You

• Our reports are not influenced by advertising. Data comes directly from EPA and other government sources.
• Phone numbers on this site connect you with independent service providers. We do not employ or directly endorse these providers.
• We may receive compensation when you call a phone number on our site, regardless of whether you hire the service provider.
• Not all pages contain advertising. Many pages are purely informational.

Editorial Independence

Our editorial content — including water quality reports, recall alerts, and rebate information — is based solely on government data and independent research. Advertisers do not influence our editorial decisions, data presentation, or recommendations.

FTC Compliance

This disclosure is provided in accordance with the Federal Trade Commission’s guidelines on endorsements and advertising. If you have questions, contact us at contact@zipcheckup.com.
