As of 2015, Amazon's general help toll-free number is 1-888-280-4331. There is also an international number at 1-206-266-2992, though charges may be applied. Amazon's customer service also offers a "call me now" button, where a customer enters a phone number and customer service calls it within five minutes.
Aside from phone availability, Amazon's customer service department offers both an email and online chat option. To do this, go to the Contact Us section of the Amazon website. Then, answer a few questions to pinpoint the specific customer service issue. Many questions are answered in this way without having to contact the department. If the question cannot be answered in this way, click on either the E-mail or Chat boxes to open a customer service ticket.
