In the search engine on the home page, there's no spot to input a corporate code, only coupon codes.

Here: https://www.nationalcar.com/en/suppo...-contract.html it says that For security reasons, at this time Corporate Contract IDs cannot be added or updated within your Emerald Club profile on nationalcar.com.

To add a new or to update your Corporate Contract ID:

• Please contact your Corporate Travel manager,
• Submit an e-mail online by clicking here, or
• Use our Member Services Contact Us Page, by clicking here, for location specific phone numbers.

I emailed them and customer service did not know how to add a corporate code to an account. What am I missing here?
