My registration number is wrong/ can’t sign up or sign in to mediacom

Good afternoon Loyalhuff,

You would want to visit Mediacomcable.com, click on My Account, and click the register now button. It should redirect you to https://support.mediacomcable.com/Registration where it should prompt you to enter your Mediacom account number which starts with 8383. The account number can be located on an invoice/statement that you received from Mediacom.

Thanks
