Overview of Area Code +86 556

Under the ITU-T E.164 international numbering plan, the full international dialing format for landline numbers in Anqing is +86 556 XXX XXXX (where X represents the local subscriber number).

Geographic Coverage and Administrative Jurisdiction
The 556 area code serves the entire administrative region of Anqing, including its urban districts (Yingjiang, Daguan, Yixiu) and all subordinate counties and county-level cities, such as Huaining, Qianshan, Taihu, Susong, Wangjiang, Yuexi, and Tongcheng. The code is exclusive to Anqing; neighboring cities in Anhui use different codes (e.g., Hefei uses 551, Wuhu uses 553).
Dialing Formats and Caller Instructions
- Local calls within Anqing: For calls between landlines within the same area code, only the 7- or 8-digit subscriber number is dialed (e.g., 1234567). However, due to the expansion of local numbering, some areas may require the full 8-digit number even for local calls. Always verify the current local dialing procedure.
- Domestic long-distance calls from other Chinese cities: Dial 0 556 XXX XXXX (e.g., 0556 1234567). The leading 0 is the domestic trunk prefix.
- International calls from outside China: Dial your country's international access code (e.g., 00 from most countries, 011 from the US/Canada), followed by China's country code 86, then the area code 556 without the leading 0, and the subscriber number: +86 556 XXX XXXX.
Numbering Structure and Overlays
Anqing's local subscriber numbers are typically 7 digits long, but some areas have migrated to 8-digit numbers to meet demand. No overlay codes have been introduced for Anqing; the 556 code remains the sole geographic code for the region. Mobile numbers in China are non-geographic and begin with 1 (e.g., 13X, 15X, 18X), so they are not affected by area codes.
