What is the difference between a suite and an apartment number?

Last Updated: March 27, 2025

The main difference between a suite number and an apartment number is their usage and context:

• Suite Number – Commonly used in commercial buildings (offices, businesses, hotels). It designates a specific space within a larger building. Example: 123 Main St., Suite 400.

• Apartment Number – Used in residential buildings (apartments, condos, multi-unit housing). It identifies a specific living unit. Example: 123 Main St., Apt 4B.

While both serve to identify specific units within a building, “suite” is primarily for businesses, while “apartment” is for residences. However, in some upscale residential buildings, “suite” may be used instead of “apartment” for marketing purposes.
