Business Page

I am setting up a business fanpage for my place of employment. To make a fanpage I have to link it to a personal account. I do not want to link it to my personal account so that others can use it in the future. I tried to set up an anonymous (fake) personal account. The problem is that it asks for my mobile number. I have an office phone number landline. How can I set up a facebook/fanpage for my place of employment without it linking to my personal information?

Thanks
