The ICS 213 History
General Message Form
The ICS 213 General Message Form was originally designed as a multipart self-copying form for use as an interoffice memo. Since its inception, both the usage and physical embodiment have changed significantly.
The ICS 213 General Message Form is now increasingly used for messages between parties who are not in the same location. Because the nature of incident communications is generally urgent, the form is often originated in one location and transmitted electronically to another location. The reply from that location is returned electronically and the two "parts" of the form are matched together.
Because of the General Message Form's increased usage between physically distant locations, the information for an ICS 213 General Message Form is often transcribed onto a blank form or entered electronically via a computer word processing program.
