The Basics of Comma Placement in US Addresses
For addresses within the United States, there are specific guidelines for comma use. Here’s a breakdown of the standard format:
The Correct Order of an Address
Before diving into commas, it's crucial to understand the standard order for a U.S. address: — Discovering Rhymes For 'Reason': A Word Lover's Guide
- Recipient's Name: The person or entity receiving the mail.
 - Street Address: The house number and street name (e.g., 123 Main St).
 - Apartment/Suite Number (if applicable): Often placed on the same line as the street address.
 - City, State, Zip Code: This is the line where commas are most critical.
 
Comma Rules
- City, State: A comma always separates the city and the state. Example: "Austin, TX".
 - State, Zip Code: Another comma separates the state and the zip code. Example: "TX, 78701".

Comma Placement with Apartment or Suite Numbers
When including an apartment or suite number, you have a couple of options, depending on the format you're using. These details are important in making sure your mail gets to the right place.
Placing the Apartment Number on the Same Line
This is a common and acceptable way to include apartment numbers. No commas are needed here.

Springfield, IL, 62704
Placing the Apartment Number on the Next Line
If you prefer to put the apartment number on a separate line, no commas are used.

International Address Formats and Comma Usage
International address formats vary widely, but here are some general guidelines.
Country-Specific Conventions
Always check the specific address format for the country you're mailing to. Many countries have unique formats.
General Guidelines
- Avoid Using Commas: In many international formats, commas are not used as frequently as in the U.S. format. Often, spaces or other punctuation marks are used instead.
 - Address Order: The order of address elements can vary (e.g., postal code before the city). Research the format required by the destination country.
 
Example: Address in the United Kingdom
Mr. John Doe
10 Downing Street
London SW1A 2AA
United Kingdom
In this example, note the lack of commas between the street address, city, and postcode.
Example: Address in Germany
Frau Maria Schmidt
Musterstraße 12
12345 Musterstadt
Deutschland
Again, commas are not used between the street address and the postal code/city.
Common Mistakes to Avoid
Understanding common errors is as vital as knowing the rules. These issues often lead to delivery problems.
Overuse of Commas
Avoid using commas where they're not required. For instance, do not put a comma between the street number and street name or before the apartment number. — Bengals Quarterbacks: A History Of Cincinnati's Signal Callers

Forgetting to Include the Zip Code
The zip code is essential for mail delivery. Always include the correct zip code.
Tips for Writing Addresses
Mastering address writing involves more than just commas. Here are some extra tips based on our practical experience.

Verify the Address Before Sending
Double-check the address using a reliable address verification tool. This can save you from returned mail and delivery issues.
Use an Address Finder
If you're unsure about the correct format, use an online address finder to validate the address. The USPS website and other online tools can help.
