US Club Callsigns

In the United States, the FCC allows any amateur radio operator to hold a club callsign for an organization under certain conditions.

According to the FCC rules, to be granted a club station license, a club should have a document of organization (minutes, bylaws, charter, etc.), a list of current officers (management), a list of members (at least four persons), and a license trustee designated by an officer of the club. An amateur can only be the trustee of one valid club station. 

The club station can have multiple call signs assigned to it under one trustee but only one of the assigned call signs can be a vanity. A Club station may not hold more than one valid vanity call sign.

In order to apply for a club call with the FCC, follow the following steps^{[citation needed]}:

1. Create an FRN for the organization via FCC's CORES application.
2. Make sure you have all requirements for application (document of organization, list of officers, list of members, trustee).
3. Fill out the ARRL's Form 605-C and submit it via mail or email to the ARRL VEC.
4. When notified, pay the FCC's $35 application fee through your organization's CORES account.

Once the fee is paid, the callsign should be available to you within 48 hours (with exceptions).
