How often must amateur radio licenses be renewed in the U.S.?

In the United States, amateur radio licenses must be renewed every 10 years. This requirement helps ensure that operators maintain a valid license and adhere to any new regulations that may be implemented. The renewal process typically involves confirming that the operator still meets the eligibility requirements and is familiar with the current rules and regulations governing amateur radio operations. By setting a 10-year renewal period, the Federal Communications Commission (FCC) balances the need for regulation with the practicalities of maintaining an active and knowledgeable amateur radio community.
