Interexchange Customer Service Center/Service Center (ICSC/SC) Codes are assigned and administered by iconectiv. An ICSC/SC Code is a four character alphanumeric code that identifies a service provider's service center as needed to do business with a trading partner typically via Access Service Request (ASR) or Local Service Request (LSR) processes.

We anticipate a turn-around time of two business days following receipt of your request and verification of information. Should our Customer Service Center need additional information to complete this process, they will contact you. When processing has been completed, the code assignment will be e-mailed to you.

If you need help or have questions, please contact the Common Language Customer Support Center at +1 (877) 699-5577 or clcsc@iconectiv.com.

Note: If your company is currently a Common Language Subscriber or you would like information about becoming a Subscriber, please contact Customer Support Center before placing an order.
