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 also provides campus-dialing service to Santa Monica-UCLA Medical Center. However, numbers ranging from 92000 to 93999 and from 95200 to 95999 cannot be dialed directly using the 319 prefix. These five-digit numbers can only be dialed from another UCLA campus number or via Santa Monica-UCLA Medical Center Hospital
