The NCPA does band planning and channel assignments within the digital segments (see Packet Band Plan).

In August 2006 the NCPA adopted the ARRL band plans for the bands above 70 cm.
In September 2009 the NCPA adopted the ARRL band plans for the bands below 2 m.
In June 2010 the NCPA adopted the ARRL band plan for the 1.25 m band.
In August 2017 the NCPA added three channels to the lower digital segment in the 2 m band, as per IARU.

The adoption of the ARRL band plans is currently under negotiations with other groups who are being asked to adopt it as well.

The ARRL is a member organization and the secretariat of the IARU and participated in the IARU band plans. However, as of this writing, there are some differences in the ARRL band plans and the IARU region 2 band plans. The HF, MF, and LF charts here are based on the latest IARU region 2 plans.

See 47CFR 97.303 for frequency sharing requirements.
