Veterans benefits mailing guides
Use these guides when you need to prepare a VA support statement or organize a benefits-related packet. PostalForm's VA Form 21-4138 workflow sends an unsigned preparation kit only to the customer or authorized signer; the customer completes the accepted signature path, evidence, and final VA submission.
