I’m getting some calls from unlisted numbers. Some of the numbers are from mobile phones and some are from land lines. For the land lines some are from Metro Manila while some are from the provinces so I compiled some list of Philippines NDD Codes to help me sort the numbers.
So what is NDD anyway? NDD stands for the National Direct Dial. It is like IDD (International Direct Dial) but its the one assigned for the Philippines provinces and cities. The usual format for the Philippines is:
+63 <NDD Code> 6 0r 7 digit telephone number
As this info may be useful to the readers I will share then here. Below are the Philippines NDD Codes of key cities and provinces in the Philippines:
