Google AdSense telephone number
You can call AdSense at 1-866-246-6453. However, it looks like a US phone number and I am a non-US resident. I haven't tried calling that telephone number as I don't want to incur international telephone call charges. I don't know if you will get connected to a machine or can eventually get to a human. If you are in the United States, and have reasons to call Google AdSense, I would very much like to learn about your experience. I hope you will leave a comment describing your experience in calling the above telephone number so that other readers will also benefit.
