In an address, “CT” almost always stands for the U.S. state Connecticut when it appears in the city–state–ZIP part (for example: “Hartford, CT 06101”).

However, if “CT” appears as part of the street name itself (like “533 Washway Ct”), it usually means “Court” , a type of short, often cul‑de‑sac-style street.

So:

  • At the end of the line with the city and ZIP → Connecticut.
  • Right after the street name/number → Court.

Quick Scoop: What does CT stand for in an address?

The two main meanings

  • Connecticut (state abbreviation)
    • Used in the city–state–ZIP part of a mailing address:
      • Example: “Hartford, CT 06101” → CT = Connecticut.
* This is the official two‑letter postal code used by USPS and other carriers.
  • Court (street type)
    • Used in the street line:
      • Example: “533 Washway Ct” → Ct = Court.
* A “Court” usually refers to a small, often quieter street, commonly ending in a cul‑de‑sac.

In some explanations, people note that “CT” can mean either Court or Connecticut depending on where it appears in the address , but these two are the practical meanings you’ll see.

How to tell which one it is

  1. Look at the position of “CT” in the address
    • If it’s after a city name and before a ZIP code (e.g., “New Haven, CT 06510”), it’s the state Connecticut.
 * If it’s directly after a street name (e.g., “Maple Ct”), it means **Court**.
  1. Use the overall format as a guide
    • Typical U.S. format:
      • Street line → number + street name + street type (St, Ave, Ct, etc.)
      • Next line → City, State (2‑letter code) ZIP.
