Catalytic Converter Labeling Catalytic converters installed before January 1, 2009 New aftermarket catalytic converters and certified used catalytic converters can be identified by a permanent stamp or label on the shell of the converter. The label/stamp should be in the following U.S. E.P.A. format: T/CA/MC XXXX YYYY. The labels do not include the EO number
T/CA/MC XXXX YYYY • T: Either “N” (for new aftermarket converters), or “U” (for certified used converters). ARB staff has found that this character is sometimes omitted on new aftermarket converters • CA: Indicates that the converter has been ARB approved • MC: A two character code for the converter manufacturer • XXXX: The converter’s part or series number. The number may be longer than 4 digits • YYYY: The date of manufacture. The first two digits indicate the month, and the last two the year

The first three X’s will be a 3 digit number corresponding to the manufacturer. The last two digits will be the specific approval number for the manufacturer. The EO number can be used to obtain information about the approval status of the converter on ARB’s website in the same manner that other aftermarket add-on and performance parts can be looked up.
