The search criteria fields are used in conjunction. For example, if you enter an NPA of 585, all NXXs associated with that NPA are displayed. But if you enter an NPA of 585 and an NXX of 924, only that row that contains the NPANXX combination of 585924 is displayed.

The NPANXX Search window contains the following search criteria.

| NPA(s) | Enter the 3-digit NPA. You can enter multiple NPAs if you separate them with commas. |
| --- | --- |
| NXX(s) | Enter the 3-digit NXX. You can enter multiple NXXs if you separate them with commas. |
| LATA(s) | Enter the 3-digit Lata number. You can enter multiple LATAs if you separate them with commas. |
| OCN(s) | Enter the OCN number. You can enter multiple OCN numbers if you separate them with commas. |
| State(s) | Enter the 2-character state designation. You can enter multiple states if you separate them with commas. |
| Zone | Select all of the applicable zones. > [!NOTE] > Note > > You can search by the default zone of 'Unassigned', or you can search by the names of the zones created in Data Management. |
