Just for information, I applied online for the EHIC with DH as the main applicant and me as a spouse.
Before I decided to just apply online, I sent an email to the enquiry address. The automated response suggested asking basic questions via their Facebook page, so I did that as well.
I got a response from their Facebook page within an hour and they told me to have DH apply online but I had to apply separately by post.
Booooo.....
I had already done the online app at the point, so I just figured I'd apply by post if my card didn't come.
The enquiry email responses (I emailed Friday and they responded on Monday) was to apply as I had with DH as the main applicant and me as the spouse.
Which is exactly what I had done.
Maybe the postal application is intended for people here on work or student visas? Well, any non-UKC who wouldn't be linked to a UKC family member.
Hopefully our cards will come in the next few weeks!
