Reportable errors
18.31

The majority of CD errors reported by law enforcement agencies and public bodies
continue to relate to the actions of a SPoC or the applicant (74%), as shown by the tables
below. This is consistent with the reported errors for 2018 and is broadly proportionate to
the roles these individuals play in handling CD applications and data.

As shown by the following breakdown, the biggest single cause of an error rests with the
applicant seeking CD upon an incorrect identifier (telephone number, username, email
address or internet protocol (IP) address). Equating to over 30% of all LEA errors, the causes
are many and varied with the overall percentage of Internet Protocol Address Resolution
(IPAR) errors remaining unchanged when compared to 2018.
