Everything You Need to Know About an Address Line

Dave Moore - July 16, 2025

Back in the day, knowing address lines was a big deal. Whether you were sending letters to friends or keeping in touch with family abroad, getting the details right was important. While writing letters has become less common, it’s still important to know address lines for things like sending and receiving packages or filling out forms.

To help you with this process, this article will walk you through the basics of address lines and how you can find them. 

What Are Address Lines?

Address lines are different parts of a complete mailing address that provide detailed information about a specific location. There are typically two address lines you’ll encounter: Address Line 1 and Address Line 2:

• Address Line 1: This line will include your house number and street name, for example, “123 ABC Street.” If you live in an apartment, suite, or a unit within a building, you’ll write “Apt 123B” or “Suite 123.”
• Address Line 2: This line is typically optional and is used for providing additional information. As an example, if your address is within a specific building or associated with a particular company, you would write “ABC Plaza” or “XYZ Corporation.”

Along with this, you’ll add the name of your city, your state, and your zip code. Incorrect or incomplete address lines can cause major issues, leading to delayed deliveries or even lost packages. 

In more serious situations, like handling legal documents or official correspondence, mistakes in address lines could lead to legal or financial consequences.

How Can You Find an Address Line?

Finding an address line can be a bit challenging, especially if you’re unfamiliar with the location or the information at hand is outdated. There are five main ways you can find these details:

Check Google Maps

One of the most reliable ways to find an accurate address line is by using online applications like Google Maps. If you have the longitudinal and latitudinal coordinates of the location, you can enter them into the search bar and find the exact address you’re looking for, including its street number, apartment/house number, and building name. 

In case you don’t have the exact coordinates of the location, you can search for any notable landmarks or well-known locations that could help narrow down your options. You can then browse the streets shown on the map and pick out the location you’re interested in to find out its exact details. 

Use a ZIP Code Lookup

For those who aren’t sure about a corporate or residential street address, city, and state, you can use the ZIP Code Lookup from USPS. 

By simply entering a zip code, you can quickly get more information about the address you need. This can help you verify the address lines and make sure that your mail or package reaches its destination without any hassle.

Check Official Documents

If you want to make sure about your own address lines, checking your official documents is a great starting point. Go through accounts, such as utility bills, tax forms, or lease agreements, and note the address you’ve written there. This will help you make sure that your address is accurate and up-to-date. 

Contact the Relevant Authority 

Getting in touch with your local authority can also be a helpful step. Your local post office can provide accurate address information as they know your area well and can also help locate your exact zip code as well. 

The municipal office is a viable option as well. The staff there handles a vast range of local data and can always direct you to the right resources. If there’s any new area you’re interested in, you can count on your municipal officers to provide reliable guidance. 

Make Use of Reverse Lookup Tool

Information.com’s reverse address lookup tool is incredibly useful when you only have partial information about an address. 

Using a phone number, email, or even a name, you can get detailed information about an address and its region. The tool gathers data from various public sources, such as government records, property records, voter registration files, business directories, and social networking sites.

All this data, legally and ethically sourced, is compiled into a highly accurate report. This report will show you the address lines that are associated with the person, email, or phone number you have entered. 

You might even get access to additional details like the person’s full name, previous addresses, social media handles, online accounts, and related contact details.

The process of using this tool is quite simple: 

1. Enter their first and last name, email, phone number, or address.
2. Add any extra details to help narrow down the search. This step is optional, so don’t worry if you’re not sure about the exact street, state, or city. 
3. Click on the “Search” button. 
4. Wait for the site to generate a report on the person or business that best matches the information you provided.
5. Review their address information and verify it to make sure it’s the right person. 

If you don’t get it right the first time, don’t hesitate to give it another try. Sometimes the data might be incomplete or outdated, but you can try again with a different combination or a more specific search.

Tips for Finding Address Lines Effectively

There are several pointers to keep in mind when you’re dealing with address lines. Keeping the following tips in mind will help make sure that you’re able to find accurate information efficiently.

• Take Care of Punctuation and Spelling: Some addresses might contain commas and periods or tricky spellings like “O’Connor” or “St. Louis.” Account for proper punctuation and the use of special characters and verify any suffixes or designations. This will be a huge help when finding and entering a complete address line. 
• Double-Check Any Information You Find: Whether you use a reverse lookup tool or contact your local post office, make sure to verify it against another source. This will help you make sure that the address lines you’ll be using are accurate and updated. 
• Take Regional Differences Into Consideration: Address formats can vary between regions. Some might require the postal code before the city name, while others place it afterward. You need to be well aware of these differences when finding an address.
• Keep Yourself Updated: Addresses can change over time, especially when there are new real estate developments or relocations. Make sure to reach out to your friends, family, and colleagues every now and then to stay updated and confirm that their address hasn’t changed. Reverse lookup tools might also sometimes provide outdated information if there isn’t public data about a person’s relocation. 
• Use This Information Responsibly: If you’re using a reputable lookup tool to search for address lines, you can rest assured that the data is extracted using legal and ethical means. However, you still need to be careful about how you use this data. Avoid using it for malicious purposes, such as harassment or identity theft, and respect people’s privacy. 
• Educate Yourself on Your Legal Responsibilities: Violating ethical and legal guidelines in your county or state can lead to serious consequences, including fines and even prison time. Make sure you have a legitimate reason for seeking someone’s address details, and avoid any unauthorized or questionable uses of the information.
