1999-Current Hotsprings Serial Number

The serial number for the the 99-current Hotsprings can be found in the equipment compartment. (where the jet pump and things are located). Always in the front of the spa inside the door panel. Serial number is on a white sticker 3x5 inches. Depending on what you have it might look like this for an example..
I-3Axxxx
The letter I stands for the model of spa it is. In this case it is for the SOVEREIGN.
The number 3 stands for the quarter of the year it was made in. In this case it was the third quarter.
Now the letter A stands for the year it was made in. In this case it is for 1999.
The xxxx indicates just a string of numbers I think its the number of the spa (not sure).
The serial number above indicates it's a Sovereign, made in the 3rd quarter of 1999.
1999 is the first year for letters in the serial number.
Heres what the years will look like:
1999= A
2000= B
2001= C
2002= D
2003= E
2004= F
2005= G

2007= I
2008= J
2009= K
2010= L
2011= M

Serial numbers for the newer Hotspring Spas are located in the equipment compartment. Where all the jet pumps and things are located. (normally the front of the spa)
From 1990 thru 1998 serial numbers should look like this. I'll take the Grandee for example for right now. G-35xxxx. Gstands for Grandee, 3 stands for the 3rd quarted it was made in and 5 is the numer of the year it was made in. In this case it was made in 1995. So you have a Grandee, made in the 3rd quarter of 1995. The X's after the first 2 numbers are numbers to indicate what number it is. not important but nice to have.
Grandee = G
Sovereign = I
Prodigy = H
