What are the consequences of exceeding Apple's Contacts size limits during iCloud sync?

What happens if you exceed the contacts size limits imposed by Apple? I am about 20 KB over the limit on my phone and curious what will happen during a sync with iCloud.

Unlike some Android devices, contacts are neither stored locally on an iPhone nor in the SIM. They are synced to an email account that you have Google, iCloud, AOL, Exchange, Outlook, Yahoo, or any Other

If you have a corporate email account added through a profile on your device, please check with your organization's system administrator.

Is this your corporate/organization/enterprise/School Management iPhone? Then please contact the system administrator of your corporate//organisation/enterprise/School Management
If it is your device, in that case, do you have any profile installed by your corporate/organization/enterprise/School Management?
1. Erase the profile added by you. If you have installed a profile on your own, --> Install or remove configuration profiles on iPhone - Apple ...
2. Please contact the system administrator of the organization who provided the profile to you
