After you sign your agreement you will receive an email from DealMaker with funding instructions, your DealMaker number is included in this email in pink font.
You can also find your DealMaker account number by logging into your DealMaker account. In the top right corner, you will see where it says your account name with a little arrow beside it. If you click on this arrow a drop-down menu will appear and you will need to select "Your Profile."
From there, under the "Basic Information" tab you can find your DealMaker account number.
