You can legally find an address from a phone number a few ways: ask the person, search the number online, check reverse phone or people-search sites, dig through public property and court records, or, if you have a reason the law recognizes, run a lookup that returns the current address from their credit file. What you can't do is trick a phone company into handing over account details, pull motor vehicle records for an unapproved reason, or use credit data without a permissible purpose.

Which method fits depends almost entirely on why you need the address. That isn't a technicality. It decides which tools you're allowed to use at all, and how current the answer will be.

## Start with why you need the address

Most people searching for an address from a phone number have an ordinary reason. Some common ones we hear:

- A landlord confirming that a rental applicant lives where they say they do.
- A lender or dealer verifying the address on a credit application.
- A contractor or small business trying to send an invoice or a demand letter to a customer who moved.
- Someone who needs to serve court papers.
- A person trying to return lost property, send a payment, or reconnect with an old friend.

Those are all fine. What isn't fine is using any of these methods to show up uninvited at the home of someone who has cut off contact, to harass or intimidate anyone, or to track down a person who doesn't want to be found. Stalking laws apply no matter how you got the address. If your reason is in that category, stop here.

## Six legal ways to find an address from a phone number

Roughly from simplest to most thorough.

### 1. Ask

It sounds too obvious to list. But for every situation where you have a relationship with the person (a customer, an applicant, a buyer), asking is legal, free and current. Put an address field on your form. If they won't give one, that's useful information.

### 2. Search the number

Paste the number, in quotes, into a search engine. For businesses, this usually turns up the company and its address within seconds. For individuals, you might find an old classified ad, a club roster, a resume or a social profile that mentions a city. Treat anything you find as a lead, not a fact.

### 3. Reverse phone and people-search sites

These sites compile public records, marketing data and old directory listings into profiles, and many will show a name and one or more addresses for a number. Free versions usually show a teaser. Paid versions show more.

Two cautions. The data is often stale, sometimes by years. And most of these sites say they aren't consumer reporting agencies, with terms that forbid using results for tenant screening, credit or employment decisions. If you're making one of those decisions, you need an FCRA-compliant source instead. We compare the two worlds in [free vs. paid reverse phone lookups](https://phonenumbercreditscore.com/blog/free-vs-paid-reverse-phone-lookup) and explain what these searches can and can't return in [what a reverse phone lookup actually shows](https://phonenumbercreditscore.com/blog/reverse-phone-lookup-what-it-shows).

### 4. Public records, once you have a name

If you've got a name and a rough location, county property records (usually through the assessor's or recorder's website) show who owns a given property, and court records can show an address listed in a case. They're reliable for what they cover. They just don't cover renters, and that's roughly a third of U.S. households.

### 5. A credit-file lookup, with a permissible purpose

This is the method most likely to return a current address, because credit files are updated constantly as lenders report accounts and people apply for credit. When you enter a U.S. phone number in our lookup, we match it to the person's TransUnion credit file and return their name and the current address on file, along with their FICO® Score 4, a credit profile summary, and phone details like line type and carrier. It's a soft pull, so their score isn't affected.

Because it's credit data, the Fair Credit Reporting Act applies. You need a [permissible purpose under 15 U.S.C. § 1681b](https://www.law.cornell.edu/uscode/text/15/1681b) for every lookup. The simplest is the person's written OK. Others include someone applying to rent from you or borrow from you, and reviewing or collecting on an existing account they have with you. Curiosity isn't on the list, and neither is finding someone who doesn't want to be found. Our guide to [permissible purpose under the FCRA](https://phonenumbercreditscore.com/blog/permissible-purpose-fcra) explains each one in plain English.

Rosa (fictional) runs a small flooring company. A customer had $2,800 of tile installed, paid the deposit, then stopped answering. Two months later, Rosa's demand letter comes back "moved, no forwarding address." The customer's account with Rosa is unpaid, which is a recognized reason to look them up. She runs the number on the work order, (555) 555-0119, and gets a current address across town. She mails the demand letter there, and if it comes to that, she knows where to have small claims papers served.

### 6. Legal process

If you're in litigation, an attorney can subpoena a phone carrier for subscriber records, and a professional process server can locate someone to serve papers. Carriers protect subscriber information and generally release it only to the account holder or in response to a subpoena or court order. That's slower and costs more, but it's the right path when a court case is involved.

## What the law doesn't allow

A few shortcuts show up in forums and get people into serious trouble. This isn't legal advice, but these are well-established lines.

**Pretexting a phone company.** Calling a carrier and pretending to be the account holder to get their address or call records is a federal crime under the Telephone Records and Privacy Protection Act, [18 U.S.C. § 1039](https://www.law.cornell.edu/uscode/text/18/1039). Paying someone else to do it is also a crime.

**Pretexting a bank.** The Gramm-Leach-Bliley Act makes it illegal to get someone's financial information from a financial institution through false statements, at [15 U.S.C. § 6821](https://www.law.cornell.edu/uscode/text/15/6821).

**Motor vehicle records.** The Driver's Privacy Protection Act at [18 U.S.C. § 2721](https://www.law.cornell.edu/uscode/text/18/2721) limits when DMV records, which include home addresses, can be disclosed. Running a license plate to find where someone lives isn't one of the permitted uses for a private person acting on their own.

**Credit data under false pretenses.** Getting a consumer report by lying about your reason is a crime under the FCRA, [15 U.S.C. § 1681q](https://www.law.cornell.edu/uscode/text/15/1681q), not just a terms-of-service violation. That's why we ask you to confirm your purpose on every lookup and keep a record of it. Our [compliance page](https://phonenumbercreditscore.com/compliance) lays out the rules, and [is it legal to look up someone's credit?](https://phonenumbercreditscore.com/blog/is-it-legal-to-look-up-someones-credit) covers the common edge cases.

## Why so many free addresses are wrong

People move a lot. The Census Bureau's American Community Survey found that [11.8% of people moved to a different residence in 2024](https://www.census.gov/topics/population/migration/guidance/acs-1yr.html), roughly one in eight in a single year. A people-search profile built from records that are a few years old will often show an address that someone left two moves ago.

Phone numbers make it worse. People keep their mobile numbers when they move across the country, so the area code tells you nothing about where they live now. Family plans mean the number might be registered to a parent. And numbers get reassigned: the person you're looking for may have dropped the number, and someone else entirely may have it now.

Check the date on any address you find, and when it matters, confirm it with a current source or with the person. Our guide to [finding out who owns a phone number](https://phonenumbercreditscore.com/blog/how-to-find-out-who-owns-a-phone-number) ranks seven methods by accuracy if you're still at the "who is this?" stage.

## If someone is using a phone number to find you

Everything above works in reverse, so here's how to make yourself harder to find.

- **Opt out of people-search sites.** Most have an opt-out form. It's tedious, and you'll need to repeat it, but it works.
- **Keep your mobile number off public profiles** and use a separate number for online listings.
- **Freeze your credit.** A credit freeze is free at each bureau and blocks most new access to your credit file. A lookup like ours comes back flagged as frozen, with no score or credit profile. See [credit freeze vs. credit lock](https://phonenumbercreditscore.com/blog/credit-freeze-vs-credit-lock) for how it works.
- **Ask about your state's address confidentiality program** if you're a survivor of domestic violence or stalking. Many states offer a substitute address for public records.
- **Call the police** if someone has threatened you or shown up where they shouldn't.

If you're dealing with a suspicious landlord or tenant rather than a stalker, our post on [verifying a landlord or tenant by phone number](https://phonenumbercreditscore.com/blog/rental-scams-verify-phone-number) is the better next read.

One practical tip if you're on the business side: get the person's written OK to check their credit at the start, on the application or work order. It costs nothing, it settles the permissible-purpose question before you need it, and it turns a customer who moved without notice into a two-minute problem instead of a two-week one.

## Frequently asked questions

### Will a phone carrier tell me who a number belongs to and where they live?

No. Carriers protect subscriber records and generally release them only to the account holder or in response to legal process like a subpoena or court order. Trying to get them by pretending to be the customer is a federal crime.

### Are people-search sites legal?

Generally, yes, for casual uses like reconnecting with someone. But they aren't consumer reporting agencies, and their terms usually forbid using results to decide on housing, credit, insurance or employment. For those decisions you need an FCRA-compliant source and a permissible purpose.

### Can I find an address from a phone number for free?

Sometimes. Searching the number online works well for businesses, and free reverse lookup sites may show a past address. Free results are often outdated, though, because they're compiled from older records.

### How do I stop people from finding my address through my phone number?

Opt out of the major people-search sites one by one, keep your number off public profiles, and consider a free credit freeze, which blocks credit-file-based lookups. If you're in danger, ask your state about its address confidentiality program and contact local police.
