This alphabetical list contains a lot of hard to find phone numbers of Computer and Internet Related companies. Use it as a rough guide which I’ll try to update periodically. It’s not perfect as I’m sure I’ve left companies out and all the phone numbers are US phone numbers with the exception of 2 companies in Canada. You may need to put a “1” in front of the Toll Free numbers where applicable. I tried to give customer service contact numbers as much as possible and used the latest phone numbers I could find. Let me know if any phone numbers have changed or are out of date. Also let me know of companies you think I should add to this list.
