Vietnam toll-free numbers have an industry-wide restriction and their access depends on local carriers.
- 120 – VNPT Fixed*, Vinaphone Mobile**, SPT
- 121 – Mobifone Mobile**
- 122 – Viettel Fixed & Mobile
* Fixed (landline) – not reachable from mobile phones on VNPT, only VNPT fixed/landlines
** Mobile – not reachable from fixed lines, only mobile phones
For maximum coverage and to ensure callers from any network can contact your business, you can purchase:
- 122 numbers since they seem to have the most market share (54% of 2021)
- Multiple toll-free numbers (120, 121, and 122 numbers) and display them on your marketing materials.
- Vietnam local numbers, which are reachable from all phones and networks in Vietnam and internationally.
