The proper format for writing a provincial address in the Philippines typically includes the name of the recipient, the building number and thoroughfare, the barangay (locality) where the building is located, the city or municipality where the barangay is situated, and the province where the city or municipality is located [1].
Here is an example of the proper format for a provincial address in the Philippines:
Recipient's Name
Unit Number + House/Building/Street Number, Street Name
Barangay Name, City/Municipality
Postal Code + Province
Philippines
For a P.O. Box address, the format would be:
Recipient's Name
P.O. Box Number, Post Office Name
City/Municipality
Postal Code + Province/Metro Manila
Philippines
It is important to note that the postal code should be placed on the left-hand side of the last line of the address, before the city or province [3].
