Following discussion on the October 5, 2022 Net, here is a modified version of Gerry Brown’s (KK7GAB) numbering scheme for the ICS-213 forms. Those filling out the forms would number them using their four letter* neighborhood code, followed by a three digit number, e.g. “NWABxxx” or “S2FAxxx”, where “xxx” is a serial number beginning with 000.
*The numbered southeast neighborhoods are identified only by the abbreviation “S” and the neighborhood number; “SE1SN” becomes “S1SN” to adhere to the four character standard.
