GDPR vs CCPA — Key Differences and What Overlaps

If your website has users in both the EU and California, you are subject to two major privacy regulations. The good news: the overlap is significant, and a well-designed compliance setup handles both. Both regulations require cookie consent mechanisms, though GDPR's opt-in requirement is stricter.

Quick summary

GDPR (General Data Protection Regulation) is the EU's comprehensive privacy law, effective May 2018. CCPA (California Consumer Privacy Act) is California's privacy law, effective January 2020, amended by CPRA in 2023. Both give individuals rights over their personal data and impose obligations on organisations that collect it. GDPR also has a more robust concept of legitimate interests as a lawful basis for processing, which CCPA lacks.

Side-by-side comparison

Jurisdiction

GDPR (EU)

EU/EEA residents. Applies to any organisation worldwide that targets or monitors EU residents.

CCPA (California)

California residents. Applies to for-profit businesses meeting certain thresholds (revenue, data volume, or data sales).

Legal basis for processing

GDPR (EU)

Must have one of 6 lawful bases (consent, contract, legitimate interests, etc.). Consent required for non-essential cookies.

CCPA (California)

Does not require a lawful basis — processing is allowed unless the consumer opts out. Opt-in required only for minors under 16.

Consumer rights

GDPR (EU)

Right to access, erasure, rectification, portability, restriction, and objection. Plus right not to be subject to automated decisions.

CCPA (California)

Right to know, delete, opt-out of sale/sharing, correct, and limit use of sensitive personal information.

Privacy Policy

GDPR (EU)

Required. Must cover lawful basis, data retention periods, international transfers, and user rights.

CCPA (California)

Required. Must include "Do Not Sell or Share My Personal Information" link and categories of data collected.

Cookie consent

GDPR (EU)

Opt-in required for non-essential cookies. Equal prominence for Accept/Reject.

CCPA (California)

No cookie consent requirement per se — but requires opt-out of data sales. "Do Not Sell" applies to third-party tracking cookies.

Fines

GDPR (EU)

Up to €20M or 4% of global annual revenue, whichever is higher.

CCPA (California)

$100–$750 per consumer per incident for data breaches. $2,500–$7,500 per intentional violation (enforced by CA AG).

Who is exempt

GDPR (EU)

No general business size exemption. Some lighter obligations for <250 employees.

CCPA (California)

Exempt if: revenue under $25M/year, AND process data of fewer than 100K consumers, AND don't derive 50%+ revenue from selling data.

What you can share between both

If you build GDPR-first, you will already satisfy most CCPA requirements with minimal extra work. Vendor agreements — called Data Processing Agreements under GDPR and service provider agreements under CCPA — are equivalent concepts:
