| TBPAG | Thousands-Block Pooling Administration
Guidelines (TBPAG), appendices, and forms. Forms include the TBP Request
forms. Check the ATIS(INC) web site
for any recent document changes. Note: Assignment of NXXs, historically made at the NXX (10,000 lines) level, has been transitioned in the U.S. to a process that assigns 1,000 lines at a time from an NXX. This supports a greater number of lines to be assigned within a given NXX and thus reduces the rate of NPA relief activities (splits, overlays). |
