To file for a duplicate license you need FCC Form 601 (Main Form). If you currently do not have an FCC Registration Number (FRN), FCC form 160 would also be required for a manual filing. If payment is due, form 159 (Remittance Advice) will be needed. These forms can be obtained at FCC Forms
. The purpose of the filing will be Duplicate License "DU".
Electronic filers would utilize the Universal Licensing System (ULS)
