This source (GlobalPlatform Card Specification) explains:

Card Data

There is a variety of card data objects. The Open Platform specification proposes only that the CPLC data should be retrievable. CPLC is an abbreviation for Card Production Life Cycle. This data object contains information about the production process of the card like the operating system or the ICC manufacturer. The Card issuer BIN data contains usually the serial number of the card. Apart from that the user defined Card issuer data can be used e.g. for deriving the keys. Some other possible values can be the available resources like EEPROM space.

In the answer to a similar question (Stackoverflow) is some info about the meaning of the number:

/**

  • Whole CPLC data from ROM and EEPROM.
  • 9F7F // TAG
  • 2A // Length of data
  • ////////////////Data /////////////
  • 4250 // ic fabricator
  • 3272 // ic type
