Confirmation Statement (New Annual Return)
1

Hi,

I am trying to submit CS01 with SIC code changes and is causing below error response. One of the codes is 4 digit code.

Resulting error: A SIC Code has been provided in an invalid format - 5 digits [SIC(07)]

The schema says the minimum length of 4 digits. Am i missing something?

Any help is much appreciated
