‘查收’ is a compound verb meaning ‘to acknowledge receipt’ — literally ‘check and receive’. The first character 查 (chá) means ‘to check, verify, or look up’, while 收 (shōu) means ‘to receive or accept’. Together, they emphasize the action of confirming that something (often digital or official) has been successfully received and reviewed. It’s commonly used in formal or semi-formal communication, especially in emails, work messages, or delivery notifications.

This term implies not just passive receipt but active verification — for example, checking an email attachment, confirming a package arrival, or reviewing a submitted document. It carries a polite, professional tone and is rarely used for physical items handed directly to someone (e.g., cash or a book), where simple 收下 (shōu xià) or 接收 (jiē shōu) would be more natural. It’s frequently paired with 请 (qǐng) in requests: ‘请查收’ (‘Please acknowledge receipt’).
