Area Code 87 – Davao Oriental

Geographic Coverage and Administrative Jurisdiction

The area code 87 is a geographic National Destination Code (NDC) assigned to the province of Davao Oriental in the Philippines. This province is part of the Davao Region (Region XI) on the island of Mindanao. The code serves the entire province, including its capital, Mati, and other major municipalities such as Baganga, Banga, Boston, Caraga, Cateel, Governor Generoso, Lupon, Manay, San Isidro, and Tarragona. The Philippine National Telecommunications Commission (NTC) allocates this code for fixed-line (PSTN) services within the province.

Dialing Formats and Caller Instructions

For local calls within the same area code, subscribers typically dial only the 7-digit local number. However, for calls from other regions in the Philippines or from abroad, the full national or international format is required.

• Domestic (within Philippines): Dial 0 followed by the area code and the local number. Example: To call a landline in Mati with local number 123-4567, dial 0-87-123-4567.
• International (from outside Philippines): Dial the international access prefix (e.g., 00 or +), then the Philippines country code 63, followed by the area code without the leading zero, and the local number. Example: +63 87 123 4567.

Overlay and Numbering Plan Considerations

As of the latest NTC updates, area code 87 does not have an overlay code. The province uses a 7-digit local number format. However, with the migration to the National Numbering Plan, all fixed-line numbers in the Philippines are transitioning to an 8-digit format by October 2019. For area code 87, this means that the local number will be prefixed with the digit 8 for existing lines, resulting in an 8-digit local number. For example, a number previously dialed as 123-4567 will become 8123-4567. Therefore, after the migration, the international format becomes +63 87 8123 4567. Always verify the current dialing procedures with your local provider.

Practical Usage for Callers

When calling a landline in Davao Oriental from a mobile phone within the Philippines, you must still include the trunk prefix 0 and the area code. From abroad, always replace the leading zero with the country code +63. Be mindful that calls to landlines are typically charged at higher rates than mobile-to-mobile calls. For businesses, it is essential to display the correct international format on websites and marketing materials to ensure global reachability.
