A complete international number is built from four parts. Here's the anatomy and the dialling order.
Number anatomy
Format follows ITU-T Recommendation E.164 the international public telecommunication numbering plan.
Press + on a mobile (hold the 0 key), or dial 00 from most countries / 011 from North America.
Dial +66. This identifies Thailand on the global telephone network.
Type the first part of the local number. Drop the leading 0 if there is one.
The remaining digits route the call to the specific line in Bangkok or elsewhere.
To call Thailand on WhatsApp, save the number with +66 and no exit prefix — WhatsApp dials from your contacts, not a dial pad. Voice and video calls are free over data.

TKOS provisions +66 DIDs and termination through direct carrier interconnects.
Whether you're reaching Thailand for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.
Bangkok is a Pacific-region destination — calls run 280–320ms round-trip and a wired headset with hardware echo cancellation handles the longer path better than earbuds.
Bangkok is ~8,360 km away — latency runs 280–310ms. Use wired ethernet to eliminate Wi-Fi jitter on this long-haul path.
Schedule Thailand calls during Bangkok business hours — 09:00–17:00 Asia/Bangkok — your contact will be at their desk in a quiet space rather than taking the call on the move.
