Yes, you can use a call tracking number with Local Services Ads, but it needs to be set up carefully. Your LSA profile should use a phone number that Google can verify and associate with your business.
A tracking number can help you see which calls came from LSA and measure lead performance. However, using the wrong number or changing your business phone information without updating your LSA and Google Business Profile can create verification or tracking issues.
The best approach is to use a reputable call-tracking setup that preserves accurate caller attribution while keeping your business information consistent across Google.
