Locate Serial Number

How to find your Master Spas serial number

Check your original sales agreement or your owner's manual. If this information is not provided in those documents, you will need to locate the serial number.

Master Spa's serial numbers are 7 characters; models 2009 and earlier start with an M and are proceeded by 6 digits. All models produced in 2010 and later will have 7 digits.

To Locate your Master Spas Serial Number:

A. On the lower part of your hot tub skirt is a metal tag which will display your serial number. Older hot tubs serial numbers are sometimes unreadable on this tag due to weather, if this is the case remove and check the back of your tag.
B. In your filter well (under your filter lid) is a sticker that has a serial number. Older hot tubs serial numbers are sometimes unreadable from the hot tub water.
C. Remove the front panel of your Master Spa. On top of the large metal or plastic control pack, there will be a sticker with the serial number printed on it.
