How do you abbreviate suite in a mailing address

When abbreviating "suite" in a mailing address, the most common abbreviation is "Ste." or "St.". Both of these abbreviations are widely accepted and used by the United States Postal Service (USPS).

Here are some examples:

• 123 Main St, Ste 101 (using "Ste")
• 123 Main St, St 101 (using "St")

You can use either "Ste" or "St" as long as you're consistent throughout your mailing address.
