• We believe that all cities (counties) of Guangdong have 3 digit city codes, but for a few cities we still do not have updated information. Your help is greatly appreciated.
• Guangzhou: The local phone number changed to 8 digits on June 8, 1996 (including Panyuu, Zhencheng, Huadu, Conghua). The rule is, add 8 before the original 7-digits if the first digit of the original number was 2-7 (2xx-xxxx to 82xx-xxxx), otherwise (8xx-xxxx) add 1 after the 8 (81xx-xxxx).
