When you need to send a registered letter to a former associate or find a distant relative for an inheritance, the starting point is often the same: a name, a first name, and nothing else. Searching for an address based on a name seems simple on paper, but homonyms, recent moves, and privacy protections quickly complicate the task. Here are the methods that really work in the field, along with their concrete limitations.
Reliability of results: why the first Google link is not enough
You type a name and a first name into Google, and you get dozens of results. The reflex is natural. The problem is that the majority of results mix up homonyms and outdated data.

A common name like “Laurent Martin” leads to LinkedIn profiles, sports results, mentions in local news articles. None of these results provide a reliable postal address. For a person with a less common name, Google may display useful snippets, but rarely a verifiable address.
The real difficulty lies in cross-referencing information. A general search engine does not automatically correlate the city, approximate age, or professional context. It is up to us to manually filter, which takes time and leaves a wide margin for error. To deepen the process, one can refer to a guide detailing how to find a person’s address by their name by combining multiple sources.

White Pages and online directories: what has changed in recent years
The White Pages remain the first reflex for many people. The service still works, but the number of individuals listed has significantly decreased. With the widespread use of mobile phones and internet plans without a landline, many households no longer appear in the directory.
The other point to know: the White Pages only display people who have not requested to be on the do-not-call list or anti-solicitation list. In practice, a significant portion of the population has made this choice.
What can still be obtained via a directory
- The name, first name, and postal address of a person listed in the White Pages, provided you know at least the city or department
- A fixed phone number associated with it, which sometimes allows for identity confirmation with a simple call
- An indication of the presence of homonyms in the same geographical area, which helps refine the search
When the directory yields nothing, we move on to the next step: social networks and specialized tools.
Social networks and people search engines: exploiting digital traces
Facebook remains, despite recent privacy restrictions, one of the most effective tools for locating someone. Many users indicate their city of residence, workplace, or school. Cross-referencing the name with a contextual element (employer, hometown) quickly filters out homonyms.
LinkedIn works well for professional searches. The profile rarely displays a postal address, but the geographical location and current company help narrow down the scope.
People search engines: an underappreciated tool in France
Platforms like Social Catfish, Spokeo, or BeenVerified aggregate public data, address histories, and information from various registers. These services are primarily oriented towards the United States, but they are increasingly indexing European profiles.
Results for French residents remain random on these platforms. Sometimes you get an old address or a phone number, but rarely a verified current address. These tools mainly serve as a supplement when other leads have yielded nothing.
Cadastral records, town hall, and public registers: often overlooked administrative leads
Few articles mention the cadastral records, yet it is a concrete resource. If the person being searched for owns real estate, the land registry service allows you to obtain the identity of the owner of a parcel. The request is made to the competent service, for a modest fee.
The town hall of the place of birth can also provide information, within a specific framework. A request for a birth certificate with marginal mention indicates marriages and sometimes the place of residence at the time of the event. This is not a complete address, but it is a solid geographical clue.
Administrative limitations to be aware of
- The land registry service only works if the person is an owner, which excludes all tenants
- Civil status documents are only issued to individuals who can prove a family link or legitimate interest
- Response times vary greatly from one administration to another, from a few days to several weeks
GDPR and legal framework: what we are allowed to do (and what we risk)
The French legal framework is strict regarding the collection of personal information. Searching for a person’s address is not illegal in itself, but the use made of it can be. Harassment, surveillance, unauthorized commercial use: these practices expose one to criminal penalties.
The GDPR has also changed access to online data. WHOIS records, which once displayed the postal details of domain name owners, now mask this information for European individuals. Registrars like OVH or Gandi have been applying this rule since the regulation came into force.
In practice, as long as the search aims at a legitimate reason (inheritance, legal proceedings, family connection) and does not use illegal means to obtain the information, one remains within the legal framework. For complex situations, a bailiff or licensed private investigator has specific access channels to administrative files, which speeds up the search while securing it legally.
The most reliable method always combines multiple sources: directory, social networks, public registers. No single tool guarantees a result. It is the patient cross-referencing of information that ultimately produces a verifiable address, provided that the legal framework is respected at every step.
