# Number restrictions in China

{% hint style="danger" %}
As of November 2023, due to industry-wide changes, Bird has discontinued call services to Mainland China.
{% endhint %}

Bird does not support call services to mainland China. This is due to the following regulations imposed by China:

* **Inbound calls only**: Chinese numbers are restricted to inbound calls and cannot be used for outbound calling.
* **International dialing only**: Chinese numbers can only receive calls from international, non-Chinese numbers. Calls with a Chinese caller ID will fail.
* **Long call duration required**: Due to strict spam monitoring and VoIP restrictions, numbers that regularly place calls under three minutes are likely to be blocked.
* **No unsolicited marketing**: Unsolicited marketing calls are prohibited.
* **Avoid high-volume, unanswered calls**: A high volume of unanswered outbound calls to Chinese numbers will result in calls being blocked.
* **Avoid repeat calls**: Repeated calls from the same origin number within one hour will result in numbers being blocked.
* **No toll-free numbers**: Using toll-free numbers for calling will result in that number being blocked.

{% hint style="warning" %}
China's strict telecommunication regulations are universal, and apply to Bird and all other carriers.
