TLC 39 is a composite symbology designed for the Telecommunications Industry. TLC 39 combines a six-digit Code 39 symbol, encoding a part number, with a linked Micro PDF417 symbol encoding a serial number and other optional information.
The first 6 characters must be numeric and include the ECI number. The 7th character is a delimiter between the linear data portion and the composite data portion, typically a comma, but other delimiters are allowed. The next piece of data is a mandatory unique Serial Number.
There can be other data fields after the Serial Number, usually either AppIDs or DataIDs, which are governed by whether or not there are alpha characters in the serial number. Country Of Origin is another typical data field that is included in this symbology.
