SIP Trunk Philippines — +63 Termination & DID Numbers
The Philippines is one of the world's largest voice BPO markets, so traffic flows both ways: offshore agents calling the US and Australia, and customers calling into Manila and Cebu. Metro Manila landlines moved to eight digits in 2019, and the 2022 SIM Registration Act ties every mobile to a verified identity.
Overview
Routing calls to Philippines
Most Philippines traffic we see ends in Manila, Quezon City and Cebu City, Davao City and Makati. Each +63 prefix is mapped to at least two carriers, and we watch ASR, ACD and PDD per prefix so a degrading route is replaced before your agents notice.
NTC sets the Philippines numbering plan, and our prefix tables follow it closely. Supported number types: geographic, mobile and toll-free. Inside the country, numbers are dialled with a 0 trunk prefix. Strip it before you send the call, and send 63 followed by the national number.
Some Philippines number ranges can be activated with basic company details, while others need proof of address. Tell us the city and number type, and we will confirm what is needed before you order.
