FAQ
Common questions
What number does a UK company have?
An eight-character company number, either eight digits or a two-letter series such as SC or NI followed by six digits. Leading zeros are part of the number, so 00445790 is not 445790.
Does the search show directors?
The result is company level, with the name, number, status and registered address. Officer records for UK companies come back from the officers endpoint once you have the number.
