Is user consent universal?

Consent obtained in one jurisdiction doesn't automatically apply everywhere. Like port clearance requiring paperwork for each country, consent requirements vary by regulation and sometimes must be obtained separately.

GDPR consent must be freely given, specific, informed, and unambiguous. CAN-SPAM allows implied consent from business relationships. Canada's CASL requires express consent with detailed records. Different standards don't automatically satisfy each other.

Geographic targeting helps: apply the strictest standard (usually GDPR) globally, or implement jurisdiction-specific consent flows. One well-documented consent process meeting GDPR standards typically satisfies other frameworks, but CASL's specificity requirements may need additional elements.
