Finding someone’s last name when you only have their first name may seem impossible. However, you can find someone’s last name as long as you have other information about the person, even if what you have is basic details like past workplaces or schools.

This article will guide you on how to find someone’s last name. Read to the end to discover effective methods for finding anyone’s last name.

5 Ways to Find Someone’s Last Name

Here are five ways to find someone’s last name. We’ll include a variety of methods so everyone reading our article will have multiple options.

1) Ask Around

Before searching the internet, start by asking around. Your friends and family might know the person you’re trying to find the last name better than you think. Since searching on the web can take considerable time, it is best to start with this simple action.

Even if the people in your social circle may not know their last name, they may be able to provide you with additional information that can help with your search. Therefore, ask around to gather leads that will assist you in your search for finding someone’s last name, not necessarily to find it.

2) Social Media Search

Countless popular social media platforms have features that allow users to find others filtering by location, including Facebook, X (formerly Twitter), and Instagram. You can utilize these filters to search for the individual you’re trying to discover the last name of.

For social media platforms that don’t have such features, such as TikTok and Snapchat, search for the usernames they’ve used in the past if you know any, and look for active accounts. You can also search posts by city or specific locations, like restaurants and cafes, and see if the person has public posts, which may lead you to their social media accounts.

3) Professional Networking Sites

If the person you’re trying to find the last name of is someone from work, use professional networking sites like LinkedIn. Similar to social media platforms, you can search for their name and filter by profession and education.

These filters also come with several subcategories that make finding someone easy. Additionally, check the “people you may know” section on LinkedIn or similar features in other professional networking sites. If they’ve connected with the people on your network, their profile might appear on this list.

4) Google Search

If social media and professional networking sites can’t help you find someone’s last name, try a simple Google search using the individual’s name and the relevant information you have. For example, you can search for their name and the school they attended to find relevant results.

Although it might sound like a simple thing to do, a Google search can help you find their last name or, at the very least, gather information that will bring you closer to it.

5) People Search Sites

Last but not least, you can use people search sites to find someone’s last name. These websites search for people on public records and web pages and trace the information you’ve provided to an individual.

While there are countless of these websites, most charge hefty fees or require a subscription to access the records. One of the few free people search sites is FreePeopleSearch.com. It is a people search free to use, allowing users to find people by name and filter by city or state.

As long as you know the individual’s name and have a rough idea of their location, you can find not only someone’s last name but also their up-to-date records that include current addresses, contact information, employment history, education, and even criminal records. 

Compared to all the other methods mentioned above, people search sites like FreePeopleSearch.com are much more effective in finding someone’s last name. Even though we’ve covered it last, it has the highest success rate for this purpose.

Furthermore, you can search for people by address or phone number. If the person you’re trying to find is a long-lost friend, you can use their past address to run a search. The same goes for phone numbers – Free People Search works even if you use a phone number that’s no longer in service.

Be Prepared for Difficulties When Finding Someone’s Last Name

You now have multiple answers to how to find someone’s last name, whether you only have their first name or other details. The methods we’ve covered can help, but you should be prepared for difficulties if you don’t have much information to begin your search.

How soon you can find someone’s last name depends on the information you have about the individual. If you know where they attended school, past workplaces, addresses, or contact details, you will have an easier time than simply starting with their first name. In any case, be prepared to spend time and effort finding someone’s last name with limited information.
