If the NL-OO is a NL-OO cum NL-AO cum NL-CC, i.e. it is functioning as a NL-OO, NL-AO and NL-CC, and then it has to be registered in the CRA as NL-OO, NL-AO and as NL-CC. For this purpose, it shall submit both the registration forms i.e. Annexure NL-N1, NL-N2 and Annexure NL-N3 to CRA. On successful registration, CRA shall allot a NL-OO registration number, NL-AO registration number and NL-CC registration number to the NL-OO cum NL-AO cum NL-CC. The NL-OO should identify the officers and their roles in CRA and accordingly allot the User ID and I-PINs to them.
