Under the ITU-T E.164 international numbering plan, the full country calling code for China is +86. Therefore, to call a fixed-line number in Dongying from abroad, you would dial +86 546 XXX XXXX, where the subscriber number is typically 7 digits long.

Geographic Coverage and Administrative Jurisdiction

Dongying is situated on the Yellow River Delta and is known for its petroleum industry, particularly the Shengli Oilfield. The area code 546 covers the entire administrative region of Dongying, including its central urban districts and surrounding counties. Key administrative divisions under this code include:

Dialing Formats and Caller Instructions

For local callers within Dongying, the area code is often omitted when dialing another fixed-line number in the same city. However, for clarity and to avoid misdialing, it is recommended to use the full national format. For international callers, the correct format is:
