No. The FHA Online Application is only for new lenders seeking FHA Approval. The lender must register each branch office and pay branch office registration fees through the Lender Electronic Assessment Portal (LEAP). A 10-digit FHA Lender ID will be assigned to each registered branch office.
For an explanation of the branch registration process, please see the LEAP User Manual located at: https://www.hud.gov/program_offices/housing/sfh/lender/ under the LEAP Information link in the Approvals & Renewals section.
