What does 'Your Merit number(Rank) is not generated' in ACPC?
If this is shown in “merit list” time then it is mainly due to the reason that either your documents are incomplete or you forgot to confirm your registration at any of alloted ACPC centre.
To rectify your problem you can call the ACPC help centre or if you live in Ahmedabad directly approx ACPc centre of VGEC,chandkheda or LD,Ahmedabad. They will confirm your document and in final list your rank will be allocated.
Hope you found solution
