# NNAG Files

The NPANXX Activity Guide (NNAG) is published monthly by Telcordia. It contains the NPANXX codes whose status changing to new, changed, or deleted in the future. You can use these monthly lists to keep your NNACL table current. To do this, import the NNAG files and then update the NNACL table.

The NNAG files have a naming convention of `NNAGmmyy` where `mm` is the month and `yy` is the year.
