PLDT subscribers in Metro Manila and some nearby provinces will have eight-digit landline numbers starting October 6, 2019 in compliance with the directive of the National Telecommunications Commission (NTC) in its memorandum no. 10–10–2017 which orders all telecoms providers in the Metro Manila area to migrate all their customers to eight-digit telephone numbers “to address the insufficient number of assignable exchange codes.”
In this regard, PRA landline numbers may become unreachable for a short period on October 5, 2019 (Saturday) while PLDT reconfigures their telephone network. Once completed, follow the procedure below to call any PLDT landline numbers with area code "02":
Dial 0 + Area Code (2) + 8 digits landline number
Example: To call the trunkline of PRA, Dial 02-8459-5000 instead of 02-459-5000
