Starting early March 2024, Customer Match lists activated on Google Partner Inventory or third-party exchange websites in the European Economic Area (EEA) will no longer be available for web and app. Google Ads and Display & Video 360 will continue to enable advertisers to use their own first-party data (as well as custom and expanded audiences) across Google’s owned & operated (O&O) properties.
Customer Match lets you reach your customers using the data they share with you. To incorporate this first-party data into your campaigns, you’ll first need to upload your data to Google Ads.
This article explains how to upload your data files. Before you begin you’ll need to create a customer list.

API upload
Customer Match upload partner (CMU)
Customer Match upload partners (CMUs) can upload match keys like email addresses, phone numbers, and mailing addresses without login credentials to your Google Ads account. You’ll need to work with your CMU partner to determine a refresh frequency.
Some of the key benefits of using a CMU to upload your Customer Match data are:
- You don’t give emails directly to Google.
- CMU completes PII protections and is privacy-safe.
- CMU pushes segmented lists to Google Ads and automatically refreshes your lists.
- You don’t need to provide Google Ads login credentials.
- The CMU can expand list size and match rate.
