Google Ads customer match not populati ng

[Bryan_Verlinden]

I’m currently running several scenarios where I link a spreadsheet with customer data to google ads customer match however it seems in Google Ads that the list doensn’t populate. I don’t get any errors however it is common that people in Belgium type their number in the following format 04XXXXXXXX rather than +324XXXXXXXX But not 100% sure that could be the issue, anyone else having issues with populating their client lists?
