Non-compliance can result in fines of up to €20 million or 4% of annual global revenue.

2. California Consumer Privacy Act (CCPA) – United States
The CCPA gives California residents the right to know what personal data—including phone numbers—is collected, sold, or shared. Consumers can opt out of data sharing and request deletion of their phone number data. Businesses must disclose how they collect and use phone numbers and provide accessible opt-out mechanisms. While similar in intent to GDPR, CCPA is more business-focused and includes provisions specific to data monetization.

It requires businesses to obtain prior express written consent before sending promotional messages or making jordan phone number list autodialed calls to mobile numbers.
