FAQ

1) Why do we need to pay?
The three-letter and telephony designator (3LD) system will expedite processing time, provide real time information, minimize processing errors and allow a State 3LD System focal point to reference designators as well as make and track requests online.
2) What happens if I already used my PIN? Can I reuse it any other way?
The PIN can also be used to track your online request for a Designator, after it has been submitted to the State.
Steps for “Online-Tracking”:
  1. On the Homepage under the heading of Industry, click “ONLINE-TRACKING”.
