how to create multiple email accounts ?

Hi all !

I've created a free zoho email account (@zoho.com).
I'd like to create a second one (I'm using a specific address for online shopping).
Now I'm unable to create that second address : sign up form tells my phone number is already used.
Isn't it possible to use the same phone # for multiple email addresses ?

Loic.
