Solution 12704: Locating the Serial Number and Manufacturing (Date) Code on TI Calculators.
Where is the serial number and manufacturing (date) code located on a TI calculator?
The serial number and manufacturing (date) code is engraved in the back casing of the calculator. To find the serial number, look for a string of numbers such as 2056018567. This number is assigned to each individual calculator.
To find the manufacturing (date) code, look for a string of letters and numbers such as I-0498A. This number is not unique, meaning one or more calculators could have the same manufacturing (date) code.
Please Note: Texas Instruments does not register serial numbers or manufacturing (date) codes. It is up to the owner of the calculator to keep this information on record.
