To celebrate Global Accessibility Awareness Day 2019 I wanted to put all the support numbers in one place for convenient reference:
Amazon Accessibility Phone Support: 1-888-283-1678
Support for various features of the devices on their website (assuming you have already developed the skills and knowledge of these features to the point where you can access the website).
Without exception, my experiences personally and with clients has always been positive with Apple Accessibility phone supoort.
Apple Accessibility Phone Support: 877-204-3930
Apple Accessibility email: firstname.lastname@example.org
Freedom Scientific (JAWS, Magic, ZoomText
Freedom Scientific Phone Support: 727-803-8600
Freedom Scientific Email Support: email@example.com
On the website linked above users may complete a form to ask a question or request a call from Google Accessibility Support. You may also email your question directly to Google at firstname.lastname@example.org . A very cool new option is to place a phone call through the Be My Eyes app. If you are a regular user of Google Accessibility, this new feature alone makes the free Be My Eyes app a must have! And no, unfortunately, there is no other way right now to make a direct call to Google Accessibility.
Google Support: 855-836-3987
Microsoft Disability Answer Desk phone: 800-936-5900
