Hi Eva,
Thanks for your reply 
Yes, this is all correct. I’ve had an email now from support, and this is what they’re saying (I replied yesterday but I’ve not heard back yet, I’m sure they’re very busy):
By the way I’ve hidden the full address and just used (rest of address)
"Here’s what we need:
Business Registration Document
Unit 1, (rest of address)
Proof of address dated within 90 days
Unit 1, (rest of address)
What you need to do:
Please visit your store’s admin:
https://www.cworks.co.uk/admin to securely upload a scanned or photographed color copy of a government-issued photo ID that matches the name of the Shopify Payments account owner.
Our analysts will review your ID within 3 business days. During that time your payouts will be temporarily paused — but not to worry, your Shopify account will continue to operate as normal and customers will still be able to purchase from your store."
This address, unit 1, is my office address, it’s what I’d initially put in “store address”.
I’d assumed what they wanted was the certificate or incorporation, is it another document that they’re asking for here?
I’m not sure why they’re asking for a business registration document at this address, the registration document doesn’t have an address on - do you know exactly what they’re asking for? I’d submitted my certification of incorporation, and there is no address on this.
When they say they want a government issued photo ID, and they’re listing my office address again, I’m confused - why would a government issued photo ID have my office address on it? I’m assuming this means they’re rejecting my driving license as it contains my home address, which doesn’t match the store address they’re quoting?
Thanks in advance
