Hello.
I bet you have reached this page in hopes of finding your DLSUCET (De La Salle University College Entrance Test) reference number, right?
Apparently, if you have lost the very precious gem you have to call, visit or mail De La Salle University Manila College Admissions Office. They can be reached at this address:
Ground Floor
Br. Andrew Gonzalez Building,
2401 Taft Avenue
1004 Manila, Philippines
Or thru these telephone numbers:
Direct Line: (02) 523-4230
Trunkline: (02) 524-4611 to 19 locals 166/167
Good luck!
