# Global Privacy Control (GPC) for U.S. Websites

GPC is the most widely recognized universal opt-out mechanism (UOOM) required by U.S. state privacy laws. Usercentrics detects and honors GPC signals automatically, supporting U.S. privacy compliance as enforcement expands.

## **GPC requirements may apply to your website**

If your website is accessible to U.S. visitors, you may be required to detect and honor GPC signals.

This signal tells your website that a visitor wants to opt out of data sale, sharing, or targeted advertising.

If your website isn't detecting and responding to them correctly, you could be out of step with an increasing number of state laws. And enforcement is increasing.

## ****What is Global Privacy Control (GPC) and why does it matter?****

GPC is a browser-based signal that individuals activate in their settings. Visitors don't have to interact with a consent banner or fill out a form. Their browser sends the opt-out signal automatically, across every site they visit.

States are actively fining businesses that fail to honor these signals, and regulators use automated scanning tools to find non-compliant sites at scale.

California will require major browsers to include built-in GPC support by 2027, significantly increasing the volume of GPC signals received.

## **U.S. privacy enforcement is accelerating**

In 2025, privacy regulators from California, Colorado, Connecticut, Delaware, Indiana, New Jersey, and Oregon formed the Consortium of Privacy Regulators to coordinate enforcement across state lines.

Their first joint action was an investigative sweep targeting businesses that failed to honor GPC signals.

Regulators use automated tools to scan websites for GPC compliance at scale. Non-compliant sites are not hard to find. There is no low-visibility way to ignore these requirements.

## **How to handle GPC signals**

Honoring opt-out signals correctly takes more than a privacy policy update. It requires detection, consistent application, and documentation across every visitor session.

### Detect every signal automatically

![](https://usercentrics.com/us/wp-content/uploads/sites/7/2026/05/wifi_tethering.svg?v=a5aa377bbdcd7e22)

Usercentrics identifies GPC signals from browsers, devices, and extensions. Where required, it displays “Opt-Out Request Honored” confirmation to visitors. No manual monitoring required.

### Apply opt-out preferences correctly

![](https://usercentrics.com/us/wp-content/uploads/sites/7/2026/05/thumbs_up_down.svg?v=ab0a9445fc776aea)

Visitor preferences for data sale, sharing, and targeted advertising are applied automatically, in line with applicable U.S. state requirements.

### Stay consistent across your systems

![](https://usercentrics.com/us/wp-content/uploads/sites/7/2026/05/Sync_icon_black.svg?v=c01b6f9619715e03)

Respect opt-out signals across vendors, platforms, and channels. Your consent logic stays aligned throughout your digital ecosystem.

### Extend opt-outs to known users

![](https://usercentrics.com/us/wp-content/uploads/sites/7/2026/05/account_box.svg?v=2cdab0db2145c605)

If you can identify a returning visitor across devices or browsers, California requires you to extend their GPC opt-out to all those sessions.

## Start with what's on your website

Run a free scan to surface the cookies and trackers active on your site and understand where your consent setup may need attention.

## **GPC compliance works better when every team is aligned**

A well-implemented GPC strategy with your CMP can do more than support privacy compliance.

### For legal and compliance teams

![](https://usercentrics.com/us/wp-content/uploads/sites/7/2026/05/Legal_icon_black.svg?v=50d2a8d7833c3597)

Automated signal detection and documented opt-out records reduce manual oversight and support audit readiness across U.S. state requirements.

### For marketing teams

Correct opt-out signal handling helps protect your data operations. Unhandled GPC signals can limit analytics reporting and measurement in Google and other ad platforms.

### For web and technical teams

Usercentrics integrates with your existing consent setup. No custom development required to detect and honor GPC signals correctly.

## How Usercentrics handles GPC for you

Usercentrics CMP is already built to handle GPC signals. Detection, application, and audit-ready records are included and don’t need additional development.

## Frequently asked questions

### What is Global Privacy Control (GPC)?

GPC is a browser-based signal that individuals activate in their settings to communicate their privacy preferences automatically. It tells websites to opt them out of data sale, sharing, and targeted advertising without requiring them to interact with each site individually.

### What is a Universal Opt-Out Mechanism (UOOM)?

A UOOM is a signal that enables website visitors to communicate their privacy preferences automatically via their browser, without interacting with each website individually. GPC is the most widely recognized UOOM under U.S. state privacy laws.

### Do all U.S. states require websites to honor GPC?

Not yet, though the trend is toward broader recognition. As of early 2026, California, Colorado, and Connecticut explicitly require recognition of GPC by name. Nine additional states require recognition of a UOOM more broadly: Delaware, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, and Texas. More states are expected to follow.

Colorado is currently the only state with a formal application and approval process for recognized UOOMs. California, Colorado, and Connecticut have each explicitly confirmed that GPC qualifies as an approved mechanism under their respective laws.

### Are regulators actively enforcing GPC requirements?

Yes. In April 2025, privacy regulators from seven U.S. states formed the Consortium of Privacy Regulators to coordinate enforcement: California, Colorado, Connecticut, Delaware, Indiana, New Jersey, and Oregon.

That September, California, Colorado, and Connecticut launched a joint investigative sweep targeting businesses failing to honor GPC signals. More multistate sweeps are expected in 2026. Regulators use automated tools to scan for non-compliant sites at scale.

### What happens if my website doesn't honor GPC signals?

Your website may be out of step with an increasing number of U.S. state privacy laws. That exposes you to regulatory fines, enforcement actions, and reputational damage. It can also affect your marketing data, as some ad platforms require correct consent signals to function properly.

### Will GPC become more common?

Yes. California’s AB 3048 requires major browsers to include built-in GPC support by January 1, 2027. This will significantly increase the number of visitors arriving at your website with GPC already active. Businesses that are not already set up to detect and honor these signals will face substantially higher compliance exposure from that date.

### How do I know if my website is currently honoring GPC signals?

The most reliable way is to test it directly. Enable GPC in a supported browser or extension, visit your website, and check whether the signal is being received and applied to your consent configuration. If you have Usercentrics CMP implemented, GPC detection is built in, you can verify signal handling through your Usercentrics dashboard.

### How does Usercentrics help with GPC?

Usercentrics CMP automatically detects and honors GPC signals as part of your consent management setup. Your team doesn’t have to manage it manually, and you won’t risk missing signals.
