List of company IDs for manufacturer specific data in BLE advertising packets

Question

Where can I find the list of registered company IDs which are set right after the AD type field in an AD Structure in a BLE advertising packet when the AD type is 0xFF (Manufacturer Specific Data)?

To be concrete, for example, how can I find the information telling that Apple's company ID is 0x4C00? (In an iBeacon packet, AD Type 0xFF is followed by 0x4C and 0x00.)

The list of two-byte Bluetooth company identifiers, sometimes called the CIC, can be found here:

The page also has a link to request a new company identifier.
