1.2. Street Address

The street address is the primary location identifier. It includes the house number and street name. Pay close attention to directional prefixes and suffixes (e.g., 123 Main St NW).

• House Number: The numerical identifier for the building.
• Street Name: The name of the street.
• Directional Indicators: NW, SE, etc., clarify the location on the street.
• Street Suffixes: St, Ave, Blvd, Rd, Ln, etc., denote the type of street.

1.3. Apartment or Suite Number (If Applicable)

If the address is for an apartment or suite within a larger building, include the apartment or suite number on the same line as the street address or on the line immediately above the city, state, and zip code.

• Apartment: Apt #
• Suite: Ste #
• Building: Bldg #

1.4. City, State, and Zip Code

The last line of the address includes the city, state, and zip code. Use the official USPS abbreviations for states (e.g., CA for California).

• City: The official name of the city.
• State: Use the two-letter USPS abbreviation (e.g., NY).
• Zip Code: A five-digit code that identifies a specific geographic area.

2. Demystifying the 5-Digit Zip Code

The 5-digit zip code is the foundation of the US postal system. It helps the USPS sort and deliver mail efficiently.

2.1. How Zip Codes Work

Zip codes are organized geographically, starting with the Northeast and moving westward. The first digit represents a broad region, while subsequent digits narrow down the location.

• First Digit: Represents a group of states.
• Second and Third Digits: Designate a specific area within that region.
• Fourth and Fifth Digits: Identify a local post office or delivery zone.

2.2. Finding the Correct Zip Code

• Omitting the Zip Code: Mail without a zip code may be delayed or undeliverable.
• Using an Old Zip Code: Zip codes can change, so always use the most current information.

3. The Power of Zip+4 Codes

The Zip+4 code is an extension of the 5-digit zip code, adding four more digits to pinpoint a specific delivery location. This enhanced code improves sorting accuracy and speed.

3.1. Understanding Zip+4 Structure

The Zip+4 code consists of the original 5-digit zip code, a hyphen, and four additional digits. These digits represent a specific delivery route, building, or group of addresses.

• First Two Digits: Indicate a sector (a group of blocks).
• Last Two Digits: Indicate a segment (one side of a street between intersections).

3.2. Benefits of Using Zip+4 Codes

• Improved Accuracy: Zip+4 codes narrow down the delivery location, reducing the risk of errors.
• Faster Delivery: Mail with Zip+4 codes is processed more quickly.
• Cost Savings: Some businesses receive discounts for using Zip+4 codes.

3.3. How to Find the Zip+4 Code

The USPS website provides a Zip+4 lookup tool. Enter the full address to find the corresponding Zip+4 code. Many online address verification services also offer this feature.

4. Addressing Envelopes and Packages: Best Practices

Properly addressing envelopes and packages is essential for ensuring timely and accurate delivery. Follow these best practices to avoid common errors.

4.1. Placement of Address Information

The recipient's address should be placed in the lower right corner of the envelope or package. The return address should be in the upper left corner.

4.2. Using Clear and Legible Handwriting

If handwriting the address, use clear and legible handwriting. Print the address if possible to ensure readability. According to a USPS study, handwritten addresses with poor legibility are 30% more likely to experience delays.

4.3. Printing Addresses: Font and Size Recommendations

When printing addresses, use a clear, sans-serif font such as Arial or Helvetica. A font size of 10-12 points is recommended for optimal readability.
