US Address Format: Examples & Guidelines

Understanding the correct US address format is crucial for ensuring your mail and packages reach their intended destination efficiently. In our experience, incorrect formatting is a common cause of delivery delays. This guide provides a clear, up-to-date overview of the standard US address format, complete with examples and essential guidelines.

Understanding the Basic Components of a US Address

A standard US address consists of several key elements, each playing a vital role in accurate delivery.

• Recipient Name: The name of the person or business receiving the mail.
• Street Address: The house number and street name.
• Apartment/Unit Number (if applicable): The apartment, unit, or suite number.
• City, State, and ZIP Code: The city, the two-letter state abbreviation, and the five- or nine-digit ZIP code.

Example of a Standard US Address Format:

Here's a breakdown using a fictitious example:

John Doe 123 Main Street Apartment 4B Anytown, CA 91234

Key Formatting Rules

Following these rules will help ensure deliverability:

• Use ALL CAPS for all address lines. (This is a USPS recommendation for optimal machine readability).
• Use standard abbreviations (e.g., ST for Street, AVE for Avenue, APT for Apartment).
• Ensure the ZIP code is correct and matches the city and state.
• Place the recipient's name on the first line.
• Include apartment/unit number on the same line as the street address, if space allows, or on the line immediately above the city, state, and ZIP code.

Detailed Breakdown of Each Address Line

Let's examine each component more closely.

Recipient Name

The first line should always contain the recipient's full name or the name of the business. If sending to a business, include the company name.

Example:

ACME Corporation John Doe

Street Address

This is the most important part of the address. Make sure the house number and street name are accurate. Use the correct street suffix (e.g., ST, AVE, RD, LN). Our analysis shows that missing or incorrect street names are a primary reason for undeliverable mail.

Examples:

123 Main Street 456 Oak Avenue 789 Pine Lane

Apartment, Unit, or Suite Number

If the address includes an apartment, unit, or suite number, include it on the same line as the street address or on the line above the city, state, and ZIP code. Use standard abbreviations like APT, UNIT, or STE.

Examples:

123 Main Street APT 4B 456 Oak Avenue UNIT 201

Or:

123 Main Street APT 4B Anytown, CA 91234

City, State, and ZIP Code

This line must include the city, the two-letter state abbreviation (as defined by the USPS), and the five- or nine-digit ZIP code. Always use the correct state abbreviation. — Jodi Arias Murder Scene: Unveiling The Evidence
