Amateur Radio call signs

According to the FCC's Vanity web page on Call Sign Availability, a call sign is normally assignable two years following license expiration, surrender, revocation, set aside, cancellation, void ab initio, or death of the grantee. However, there are exceptions to this two year waiting period. Please see "FCC Rules" section below.
