- More than USD 50,000 total lifetime spend. For advertisers whose accounts are managed in currencies other than USD, your spend amount will be converted to USD using the average monthly conversion rate for that currency.
If you want to start using Customer Match and you meet the requirements above, you’ll need to contact your assigned account manager to request access to Customer Match.
If you’ve never used Customer Match and don’t have an assigned account manager, your account is currently ineligible to use Customer Match, even if it otherwise meets the requirements above. In the future, we’ll offer an application process for advertisers who meet these requirements and want to request access to Customer Match. An announcement will be made when the application process becomes available.

Formatting Guidelines (Emails, Mailing Addresses & Phone Numbers)
Files must follow specific formatting guidelines in order to be accepted. Incorrect formatting, including incorrect hashing, can lead to an upload error or a low number of matched records. Please check all of the below items, as not following all guidelines can cause a low list size. For additional formatting guidelines.
1. Files must be in CSV format (and cannot contain multiple tabs)
2. All identifiers for one user record must be comma-separated. Different user records must be
separated by the standard unix newline character \n or a line break. They cannot be separated with a
space or semicolon
3. Headers must only be Email, First Name, Last Name, Country, Zip, Phone (multiple email, postal
columns and phone number columns are allowed)
4. Multiple email addresses, mailing addresses and/or phone numbers can be provided for a given user
by including duplicate columns. Providing multiple postal codes for a user enables us to match on
both work and home addresses.
5. The order of the columns in the .csv file does not matter. We will use the column headers to identify
the data type.
6. Email is not required if advertiser is only uploading mailing address and/or phone number data
Additionally, if you’re hashing before you upload your file:
1. If advertiser is pre-hashing the data, they must use SHA256
2. Don’t hash Country or Zip columns
3. Lowercase all characters and remove all extra spaces before, after, or in between email addresses
Other file requirements:
● Maximum upload list size: no limit
● Number of lists per account: no limit
● Serving minimum: 1,000 matched records
Creating a list on Google Ads
- Log into your AdWords account and navigate to Settings > Audience Manager
- Click the blue ‘+’ button and select ‘Customer list’
- Under ‘Audience Name’, give your list a name
- Under ‘List Members’, select which type of customer data you will be uploading
- Under ‘Upload Data’, select the radio button indicating whether your data is unhashed or hashed
a. You can upload a file of un-hashed emails in AdWords and the emails are automatically
formatted and hashed before they are sent securely to Google’s servers. The hashing is done
locally on the computer that is used to upload the files, and therefore can be done securely from
within an advertiser’s own corporate network.
- Select ‘Choose File’, navigate to the proper file on your machine and click ‘Open’
- Once uploaded, check the box indicating the data was collected and is being shared with Google in
compliance with Google’s Customer Match policies
- If you’d like to customize the membership duration or give the list a descriptive name, you can do so at
the bottom of the screen.
- Click “Upload and Save List”. You will receive a notification if there are formatting errors in your file.
- After a list is saved, it will show an “In progress” status until it has finished uploading, which can take up to 24 hours. The advertiser will see a list status change in the AdWords UI when the file has been uploaded, matched successfully, and is eligible to serve (has met the minimums). If you see “In progress”
- for more than 24 hours or if you see ‘error with the last upload’ the system has timed out and re-uploading
the list will fix the issue – please ask your client to re-upload the list.
Note: If you combine any form positive targeting with a negatively targeted Customer Match list, your campaign may begin serving before the negative targeting takes effect. To ensure that your negative targeting takes effect for newly uploaded Customer Match lists, we recommend that you wait 24 hours after the list is uploaded to begin the campaign.
