Punctuation Rules for Compass Point Abbreviations
The use of periods after compass point abbreviations depends on whether the abbreviation consists of one letter or two. These guidelines are especially important when indicating directional ends of a street or quadrants of a city within a numbered address.
Single-Letter Abbreviations
For single-letter abbreviations of compass points like North (N), South (S), East (E), and West (W), a period is generally required. This applies when they are used to specify a direction in an address.
- Rule: Use a period after a single-letter abbreviation.
- Examples:
- N. for North
- S. for South
- E. for East
- W. for West
Two-Letter Abbreviations
When compass points are combined to form two-letter abbreviations for quadrants of a city, such as Northwest (NW), Southeast (SE), Northeast (NE), and Southwest (SW), a period is not typically needed.
- Rule: No period is needed after a two-letter abbreviation.
- Examples:
- NW for Northwest
- SE for Southeast
- NE for Northeast
- SW for Southwest
Practical Examples
Understanding these rules ensures addresses are correctly formatted and easily understood.
