Addresses in text
When to abbreviate versus spell out:
- In expository text, only avenue, boulevard and street are abbreviated (Ave., Blvd., St.) and only when used as part of a numbered street address.
- All other street suffixes (drive, road, alley, etc.) are spelled out in all instances.
- Capitalize a street suffix when part of a street name without a number, but don’t capitalize it when used alone or with two or more street names: Mill Avenue, Rural and Baseline roads.
Figures or numbers?
- Use figures for address numbers.
When to spell out numbers:
- Spell out and capitalize First through Ninth when used as street names; use figures and ordinals for 10th and above.
Superscript, th or th:
