How do I determine if a thousands-block is contaminated or not?
We recommend that you query the NPAC to determine if a thousands-block is contaminated. For assistance with performing the NPAC queries, contact the NPAC help desk at 1-888-NPAC-HEL(P) or 1-888-672-2435. Another way of determining if a thousands-block is contaminated or not, is by going to “Reports” located on the www.nationalpooling.com website. Select “Block Report”, then enter the state, NPA, rate center and select the “Available Blocks” radio button, then click “Continue”. Under the “Contam (Y or N)” column, if there is a “Y” then the thousands-block has been reported as contaminated. If there is a “N” then the thousands-block has been reported as pristine.
