DialiNg iNstructioNs
CTS telephone service provides station-to-station
campus dialing for the UCLA community. A
campus telephone number is identified by the last
five digits of its seven-digit telephone number.
UCLA telephone service that extends to UCLA
facilities off campus is called Extended Campus
Service (ECS). It is part of the five-digit campus
dialing plan and offers most UCLA telephone features.
UCLA telephone numbers are located within
the 310 area code and encompass one of the
following prefixes:
206 267 312 319 794 825 983
To identify the full seven-digit UCLA telephone
number, match the last digit of the prefix to the
first digit of the five-digit number. CTS provides
campus-dialing service to Santa Monica-UCLA
Medical Center. Santa Monica – UCLA Medical
Center maintains some lines that cannot be dialed
directly from off-campus numbers using the entire
7-digits. These numbers can only be dialed from
another UCLA campus number or via Santa Monica-
UCLA Medical Center Hospital Communications using
their five-digit extension.
Access to non-UCLA campus numbers requires
dialing 8 first. The allowable calling area is based
on the telephone line’s class of service.
