Frequently asked questions
How many Thailand area codes do you cover?+
We cover all 5 area codes in Thailand, for example +66 2, +66 52, +66 33, for local numbers, hosted PBX and SIP trunks.
How do I pick the right Thailand area code?+
Choose the code for the city where you want a local presence. Our team helps you pick the code your customers recognise.
Can I combine several area codes on one trunk?+
Yes. All your numbers, whatever the area code, land on the same SIP trunk or PBX instance.
Are calls to these area codes billed differently?+
Outbound rates depend on the destination type (fixed, mobile, special), not on the area code itself. Billing is per second.
Can I port an existing number and keep its area code?+
Yes. Porting keeps your area code and number with zero downtime, usually within 2–4 weeks.
Do these numbers support emergency calling?+
Yes, where local regulation allows. We register the emergency address tied to each number during onboarding.
