厂址 (chǎng zhǐ) is a compound noun meaning 'factory site' or 'plant location' — the specific physical address or land where a manufacturing facility is situated. The first character 厂 (chǎng) means 'factory' or 'plant', while 址 (zhǐ) means 'site', 'location', or 'address'; together, they denote the precise geographical spot occupied by an industrial operation. This term is formal and commonly used in business, logistics, urban planning, and official documentation.

Unlike more general terms like 地址 (dìzhǐ, 'address'), 厂址 specifically implies an industrial or production context — it’s rarely used for offices, shops, or residences. You’ll often encounter it on company websites, regulatory filings, shipping labels, or when discussing relocation, zoning approvals, or environmental assessments. It carries a technical, administrative tone and is seldom found in casual speech.
