For ESF funded learners, this field is collected for the Priority 2 part of the programme.
This field is collected for all apprentices on all funding models (including Funding model 99).

  • From 1 April 2022, new Employer Identifier numbers are no longer issued. Please use a value of 999999999 where the employer does not exist on the Employer Data Service. There is no longer a requirement to update this within 60 days.

  • This field must contain a valid employer number from the Employer Data Service (EDS).

  • Self-employed learners will require an employer number from the EDS.

  • The data recorded in this field will be validated in the data collections web portal against a copy of the employer table from the EDS database.

  • If the learner's employment status is unemployed, this field does not need to be returned. Once the learner becomes employed, a new Employment Status record must be returned with the employer number recorded. This is particularly important for apprentices who should have an employment status record detailing who they are employed with on the first day of the apprenticeship programme.

  • For traineeships, the work placement Employer ID is not collected in the Employment Status record. Data about the work placement employer must be recorded in the Work
    Placement record.

  • Employer numbers can be found on the Employer Data Service:
