The GeoScrub APIs help you comply with time-of-day calling restrictions by providing timezone information and legal calling window validation for phone numbers.

Why GeoScrub Matters

Federal and state telemarketing laws restrict when you can contact consumers. The TCPA establishes a baseline of 8 AM to 9 PM in the consumer’s local time, but many states have stricter rules. GeoScrub eliminates the guesswork by:
  • Determining the timezone for any North American phone number
  • Calculating legal calling windows based on federal and state regulations
  • Accounting for holidays and state-specific restrictions
