CIS Monthly Return Submission Error

SUGGESTED

Hello,

Having spent hours on the phone to sage they are saying its an HMRC issue not sage.

Error as follows:-

Error: 5012 Message: cvc-type.3.1.3: The value '355350211' of element 'CRN' is not valid.
Error: 5012 Message: cvc-pattern-valid: Value '355350211' is not facet-valid with respect to pattern '[A-Za-z]{2}[0-9]{1,6}|[0-9]{1,8}' for type 'CRNtype'.

We have checked every company number reverifed every subcontractor but keep getting the error

Has anyone else has problems recently or had this error?

Many thanks
