Job Aid Description/Purpose

This job aid provides training on how to effectively use the automated PIC and LPIC verification process. This product will allow you to submit and receive batch files containing requests for PIC/LPIC data on CLEC owned end-user accounts. These batch files will be sent and received in a format called Customer Account Record Exchange (CARE) which is an industry standard for transmission and receipt of data files. In this instance the files will communicate information about the end-user customer to the CLEC.

When you request PIC/LPIC validation from CenturyLink™, the validation takes place electronically and the data requested is returned to you in the CARE format.

Please visit the Electronic Access web page to download the forms required to request batch file processing for PIC/LPIC data access. Please read the instruction before completing the form.
