Primary Interexchange Carrier/Local Primary Interexchange Carrier (PIC/LPIC) Verification - V7.0

History Log


CenturyLink™ has designed a Primary Interexchange Carrier/Local Primary Interexchange Carrier (PIC/LPIC)

Verification service that provides you with an electronic process for submitting accounts and having the central office PIC/LPIC programming checked on these accounts. "Real-time" switch verification is done so that you will receive accurate PIC/LPIC verification information.

PIC/LPIC Verification allows you to verify the PIC/LPIC data on your accounts. You will electronically send a file to CenturyLink, and CenturyLink will check the PIC/LPIC information in the central office switch and then send back an output file with responses.

The exchange of account information is at the Working Telephone Number (WTN) level. Output (notification and confirmation) is produced at WTN level detail.

The PIC/LPIC Verification service does not update any of your databases. It is only a verification process.

This process does not utilize Reseller Identifications (RSIDs) or CLEC Identifications (ZCIDs). The Regional Subscription System (RSS) requires a four digit number that represents the Competitive Local Exchange Carrier (CLEC). The Operating Company Number (OCN) also known as Local Service Provider Identification (LSPID) is used. A separate file must be submitted for each LSPID. LSPIDs cannot be mixed in one input file.

An electronic file will be created to send to CenturyLink for real-time PIC/LPIC switch verification. That file is to be formatted in the industry standard 1500 byte Customer Account Record Exchange (CARE) format.

Once the electronic file is received, CenturyLink internal systems will verify the ownership of the telephone number to confirm that you own the telephone numbers in the batch file. Ownership will be determined by comparing the LSPID of your request to the LSPID at the WTN level. If the telephone number belongs to you, the PIC/LPIC Verify process will proceed.

If you do not own the telephone number, a reject message will be sent in the output file. If the account passes through that first edit, the appropriate central office switch will be queried for the current PIC/LPIC information for each account on the file.

Requests from CLECS who have an alpha-numeric LSPID will need to be handled manually. CLECS in this situation will need to contact their service manager for assistance.


PIC/LPIC Verification is available throughout CenturyLink QC.

PIC/LPIC Verify processing occurs only Monday through Saturday but input files are accepted Monday through Sunday.

Input files submitted Monday through Saturday are processed the same day received. Output files will be sent within 48 hours.
