Seven-digit dialing begins--authorization code users, please note change

The campus moved to 7-digit dialing today, as announced. Here's a recap of the two main changes, plus additional information if you use campus authorization codes to charge the cost of phone calls.

(The codes are on-campus versions of calling card numbers, and if you don't know what an authorization code is, you probably don't have one.)

When you use a campus phone:

  • If you're calling another campus phone number, you now dial the full 7 digits. Just add "75" to the front of the 5-digit campus number you want to reach.
  • If you're calling an off-campus number, you no longer dial "9" or "91" first. Just dial the 7- or 10-digit number directly, like you would on a cellphone.

When you use an authorization code:

  • You now begin by dialing "1001," instead of "5," and you no longer have to dial a "9" and/or a "1" when calling. The rest of the process is unchanged. After dialing 1001, you'll dial the phone number you want to reach, and then be prompted to enter your authorization code. After you enter it, your call will be completed.

Last week, IET-Communications Resources contacted customers who used the codes, sent details about the code change to campus area telephone representatives, and updated the dial-change FAQ at myphone.ucdavis.edu with information about the code.

Using an authorization code assigns the cost of the call to a designated account, so the person who owns the line doesn't have to pay for the call. People might charge different calls to different grants, for example, said Service Manager Zack O'Donnell. The service is somewhat dated, because the cost of individual calls is usually miniscule. But there are hundreds of the codes out there, and some are still in use, he said.
