Its not the AB centre number though is it? From the entry form, it states:
NCN (National Centre Number): Where an institution (e.g. a school orcollege) attended by the candidate has made a significant contribution to their work towards the exam (for example, if the lessons take place at school/college), please record the institution's National Centre Number.The Examinations Officer at the school or college in question will be able to confirm the relevant NCN,which is issued by the Joint Council for Qualifications (JCQ). Recording the NCN allows the capture of examination data for School and College Achievement and AttainmentTables (this data is passed on by the Board to the DfES in strict confidence– see Regulation 17m).
