With that said, we were able to find customer service contact numbers more quickly on Yahoo than Google because Google and associated Google properties have a tendency to push customers into a peer guided forum or FAQs section to get lost before offering a phone number as a means of customer service.

We found one phone number openly listed for Yahoo customer care, but there are a few other numbers you may find helpful in your quest for customer service. Billing Customer Service 1 8. Stl Files For 3D Printing Downloads. Billing TTY 1 8. Corporate Office 1 4. Corporate Fax 1 4. Mailing Address. Yahoo is the only company weve reviewed that offers complete directions and help getting to the corporate office. You can read detailed directions and instructions for VTA Light Rail, VTA Bus, Calltrain, Amtrak Capitol Corridor and Altamont Commuter Express. They even offer driving directions from San Jose and San Francisco. Yahoo Inc. 7. 01 1st Ave. Sunnyvale, CA 9. 40. Official Website. The official website for Yahoo is http www. This site is the starting hub for many other Yahoo sites, but not all sites are linked from the main page. If you need help from a specific Yahoo department, such as the Small Business or Advertising departments, it is best to visit the main page for those divisions rather than searching for help on the main page of Yahoo. Customer Service Email. A traditional email address for customer service is becoming a thing of the past. A smaller, leaner customer service budget can be used to man Facebook and Twitter, which means more profit for big companies. Customer service staff manning phones and email addresses is extremely expensive and require extensive training. We found one dedicated email address for media, but we found several virtual connections to customer service. We were unable to find an email address or contact form for customer service, but we did send a message to Yahoo customer care via Twitter. Our Experience. We were never able to find a main customer service phone number so we gave billing customer service a call. The call was immediately answered with a warning message telling us we would have to wait a LONG time to talk to a representative. You cant press 0 to push through the system, so we chose Mail Premium Billing. The call was transferred to customer care. We were told the wait time would be two minutes, but the call was disconnected after wed been on hold about a minute. We called back and pushed through the entire system again and the call was disconnected again.
