The data entered in the Property Address section of Validate Borrower/Address for Case Number Assignment is validated against United States Postal Service (USPS) information.
If the address you entered is correct but did not pass USPS verification, check the Override Address Validation checkbox (available only when address validation fails) to temporarily bypass address validation. The entered address is used for continued processing, but this address is marked as not validated against the current USPS data recorded in HUD’s system. The Mortgagee must verify that the address is valid prior to endorsement. If the street address is undetermined because of proposed or current construction, the lot, block, and plat information for the property may be entered temporarily instead. For a preconstruction property, the case number can be assigned, but the address information must still pass validation prior to endorsement.
