Multiples end-users with same email

Hi,

I have a similar problem. At this point we have 5 brands en zendesk and in the core of our sytem. For our system the unique key is a number, so we can have several customer with same email. Each brand sell diferent things and has different user fields. 

We need to upload those customers to zendesk by API but at this point the information of the last customer updated overwrites the information of the first one. Is ther any way to create few customers or profles with same email (i dont know if using organzations, brands, profiles etc) but different customer fields values? 

Moreover the information of the customer must be visible only for the the agents in charge of this brand/organization

Hello Dave, the identification of my clients is by CPF, which is a unique identification here in Brazil.

However, I have numerous cases of families in which both have an account, so they are different CPFs and different names, but they use the same email between them.

In macros, triggers, etc., we use the user's name for messages, and then we should use the name that refers to the CPF that is being treated.

Hi Lou.
Zendesk doesn't really allow it and this is a problem today because I have this situation since my system doesn't use email as a key and allows me to have multiple accounts with the same email.

Hi CJ.

I am currently using this solution of including the + in my users' email, for most cases, this solves well but it doesn't work for all and I have a regulation in which I need to communicate my client his number protocol when a request is created in addition to responses from my agents.

Hi Anderson, 
So, I'll get this piece out of the way first, generally speaking, a user cannot create 2 accounts in Zendesk under the same email, so this situation should not be able to happen for most accounts. If you've got outside authentication hooked in or imported users though, then you could run into all kinds of situations that wouldn't normally possible, like this one. 

Good news, there's still a way to fix a situation like this. I actually use this a lot. The vast majority of email providers support plus signs and extra text in emails as a way of adding forwarding addresses. That means I can set up an account for cj.support@company.com and one for cj.support+childaccount@company.com. Both of those addresses send to the same inbox, cj.support@company.com. You can have as many plus sign variations for a single email as you want or need. There's no set up either, so the customer doesn't need to provide anything. I should note that the receiver can see what you put after the plus sign, so make sure it's appropriate to be customer facing. 

Now that you can have two separate account profiles for the email, you can set up different user tags on each, and use those tag to direct the triggers and notifications for each. 

How are 2 users able to have the same email address? ZD doesn't allow that?
