CRM and Website Compliance by Region: What US, UK, EU, and Singapore Businesses Need to Know

Data privacy rules differ meaningfully by market, and "just be GDPR compliant" isn't quite a complete answer even for businesses that only sell into Europe. Here's a practical map of what actually applies depending on where your customers are, and where to go for the full detail on each.

This is a practical overview from a CRM and website consulting perspective, not legal advice — confirm specifics with a qualified privacy lawyer for your situation.

United States — CCPA and state-level privacy laws

The US has no single federal privacy law; California's CCPA is the most prominent and the de facto benchmark most businesses build toward, with several other states now running similar laws. It applies based on specific revenue and data-volume thresholds, not to every business by default. See CCPA and Your CRM for what it actually requires.

United Kingdom — UK GDPR

Post-Brexit, the UK runs its own near-identical copy of GDPR, enforced by the ICO rather than an EU data protection authority. The practical requirements are close to EU GDPR, with some UK-specific enforcement patterns worth knowing — the ICO has generally taken a proportionate approach toward small businesses acting in good faith. See UK GDPR and Your CRM.

European Union — GDPR

GDPR applies EU-wide and, importantly, extraterritorially — a non-EU business serving EU residents can still be covered. It's the strictest of the four regimes covered here and the one most businesses should design toward first, since it covers most of what the other three require plus additional specifics around cross-border data transfers and vendor data processing agreements. See GDPR for European Small Businesses.

Singapore — PDPA (and a genuinely useful grant)

Singapore's PDPA covers consent, purpose limitation, and breach notification, broadly similar in spirit to GDPR but with its own specific requirements around the Personal Data Protection Commission (PDPC). Singapore also runs the PSG grant, which subsidises CRM and other IT adoption costs — a concrete financial reason to get this right early, unlike anywhere else on this list. See PDPA Compliance and the PSG Grant.

How these four actually compare

	Applies to	Enforced by	Key requirement	Unique feature
CCPA (US)	Businesses over specific thresholds	State attorney general / CPPA	Opt-out of data sale, deletion rights	No blanket federal law
UK GDPR	Any business serving UK residents	ICO	Lawful basis, consent, subject rights	Near-identical to EU GDPR
GDPR (EU)	Any business serving EU residents	National DPAs	Lawful basis, consent, DPAs with vendors	Extraterritorial reach
PDPA (Singapore)	Any business handling Singapore residents' data	PDPC	Consent, purpose limitation, breach notice	PSG grant subsidises compliant tools

The practical starting point

If you sell into more than one of these markets, build your CRM and website data practices to GDPR's standard first — clear consent, a documented lawful basis for processing, and straightforward data access/deletion — and you'll cover most of what CCPA and PDPA require as well, with narrower region-specific gaps to close rather than four separate compliance programs.
