The FCA must allocate to every protected cell company a number, which is to be known as the protected cell company’s registered number.

Protected cell companies’ registered numbers must be in such form as the FCA may determine from time to time, and may consist of one or more sequences of numbers or letters.

The FCA may, upon adopting a new form of registered number, make such changes to existing registered numbers as appear to it to be necessary.

A change to a protected cell company’s registered number has effect from the date on which the protected cell company is notified by the FCA of the change.
