Registration requirements vary from State to State. Most States require you to complete an absentee ballot application to start the absentee voting process. FVAP encourages the use of the Federal Post Card Application (FPCA) to start the absentee voting process as it is standardized for use across all States and territories and will extend your eligibility to receive a ballot for all federal elections in which you are eligible, based on State-specific guidelines. The FPCA acts as both a registration and absentee ballot request form.
