What model is your vacuum?

The 10 digit serial number on ALL G series Kirbys (G3, G4, G5, G6, Ultimate G, Diamond Edition, Sentria and Sentria II) is engraved into the aluminum on the side of the Kirby, right above where the cloth bag attaches to the machine. This serial number contains the EXACT manufacture date of the machine.

The first number in the serial number pertains to the factory it was made at. The second and third number is the year of manufacture. The fourth and fifth numbers are the month of manufacture. The rest of the serial number tells you what number in production it was for that month and year.

FOR EXAMPLE.... in the serial number 1071104984, the machine was manufactured in November of 2007 and was the 4984th Kirby manufactured in Cleveland in that particular month.

Thanks for the information.

Were the serials before the Dual Sanitronic only #s or were they coded somehow, too?

Do you have a list of serials and time periods like that for Electrolux machines?

<span style="font-family: 'trebuchet ms', geneva;">I have a Kirby G5, with the serial number 2980705289.  Using the information provided in your post, would I be correct in saying that my machine was made at the Andrews, TX plant in July, 1998, and was the 5,289th machine off the production line at that time?</span>

I have an issue with this information.

I just got a Sentria II with a serial number of 2100905057.

According to this info that means it was made in September 2010. But Kirby says the Sentria II did not start production until 2012?
