Stripe are asking for a Company Registration Number. What do I do?

When you create your Stripe account, you may be asked for a Company Registration Number (CRN). This is based on the type of business that you select; not all business types require a CRN. 

If you select Non-profit -> Individual/Sole Trader or Unincorporated Association, you won't need to provide a CRN. 

You may need to go back a few steps in the registration form to change your business type.
