Writing an address for an apartment correctly ensures timely mail delivery and presents a professional image to landlords, employers, and clients. This guide breaks down the exact format, explains international variations, and highlights common pitfalls to avoid.
Understanding the Core Components
Every address line relies on a specific sequence of elements that move from the most specific to the most general. For an apartment, this means starting with the recipient and ending with the broad geographic region.
Line 1: Recipient Name and Apartment Number
The first line is the foundation of the delivery address. It must combine the person's name with the unit identifier to eliminate confusion. Use the full name or a standard abbreviation for the apartment designation.
John Doe

Jane Smith
Building the Standard Address Block
Following the core recipient line, the subsequent lines organize the location into a logical hierarchy. This structure is critical for automated sorting machines used by national postal services.
Line 2: Street Address and Unit Designation
This line merges the physical street location with the apartment identifier. Consistency in abbreviations is key to preventing delivery delays.
Line 3: City, State, and ZIP Code
Always separate the city name from the state abbreviation and ZIP code with a comma for clarity. The state should always use the official two-letter postal abbreviation.
Springfield, IL 62704
Riverside, CA 92507
International Address Considerations
When writing to countries outside the United States, the order often reverses, placing the city name before the street address.
United Kingdom and Canada
In the UK, the postcode is essential and usually appears on the same line as the town. In Canada, the postal code includes a space and should be the final element.
Japan and China
These regions use a hierarchical system where the largest administrative division is listed first. Apartment numbers typically follow the building name rather than the street.
Common Mistakes and Solutions
Errors in formatting usually stem from ambiguity or the use of non-standard symbols. Avoid these issues to ensure smooth delivery.
Using "P.O. Box" instead of a street address when a physical location exists.
Omitting the apartment number entirely, leading to misdelivery.
Using symbols like "@" or "&" which confuse optical character recognition scanners.
Formatting for Digital and Professional Use
When entering an address into online forms or company databases, follow the specific formatting instructions provided. Some systems require the apartment number in a separate field to prevent errors.
Subject Line and Salutation
In email or official correspondence, include the apartment number in the subject line if space is limited. In the greeting, always use the correct unit number to ensure the recipient recognizes the communication.
