The serial number (also referred to as the meter number) is the identification number registered with the postal carrier for the postage meter license of your franking machine.
This number shows on the identification tag on a white sticker located at back of the franking machine. The Product Code Number (PCN) is the franking machine type. The serial number (Meter #) is a 7-digit number, beginning 66... (G920 and G922).
The Incidia is printed on franked mail in the top right-hand corner, under/beside the postage amount. It is identical to the Meter # but with PB in place of the first digit.
Please always quote the Meter # for your franking machine when contacting Technical Support.
