Overview
The character 码 (mǎ) primarily refers to numbers, codes, or units of measurement. It is commonly used in contexts such as postal codes (邮政编码), clothing sizes (尺码), and digital codes like QR codes (二维码).
Common Uses
- Postal codes: 邮政编码 (yóuzhèng biānmǎ) are essential for mail delivery.
- Clothing sizes: 尺码 (chǐmǎ) indicates garment sizes, often numeric.
- Digital codes: 二维码 (èrwéimǎ) refers to QR codes used for scanning and payments.

Usage Notes
When 码 is used for sizes, it usually follows a number (e.g., 32码). For codes, it often appears in compound words. Avoid confusing 码 with 马 (mǎ, horse), which is a different character with the same pronunciation.
Register and Tone
码 is neutral in tone and commonly used in both formal and informal contexts, especially in everyday life and commerce.
