Key takeaways
- Domain registration collects contact details that can appear in the public WHOIS record, which for many small businesses means a home address.
- Since privacy rules tightened in 2018, registrars redact much of the personal data in WHOIS, and most offer a privacy or proxy service, but those can lapse or be inconsistent across domain types.
- Putting a real business address on the registration is the more durable fix, since it keeps your home private even if a privacy service is off, expires, or does not apply.
Before you start
- Check what your registrar currently shows in WHOIS for an existing domain before you assume it is private.
- Decide on a business address you are comfortable being public, in case a privacy service does not fully apply.
Who this is for
- Founders registering a domain who do not want their home address public.
- Online businesses relying on a registrar privacy service they have not verified.
- Anyone deciding what address to use for a domain registration.
When you register a domain, the contact details can end up in the public WHOIS record, and for a small business that often means your home address. WHOIS is the public lookup for who is behind a domain, and the data you enter at registration is what can be exposed.
This guide covers how WHOIS privacy actually works today, where it falls short, and why putting a real business address on the registration is the more durable fix than relying on a privacy service alone.
What WHOIS Exposes
WHOIS is a public directory that records the registrant, administrative, and technical contacts for a domain. Historically, that meant the name, address, email, and phone you entered were openly searchable by anyone, which is how a home address used at registration becomes public.
- Registrant contact: the person or business that owns the domain, including the address entered.
- Administrative and technical contacts: additional details that can carry the same address.
- Anyone can run a WHOIS lookup, so an exposed address is public to customers, competitors, and spammers alike.
How WHOIS Privacy Works Today
The picture changed in 2018, when privacy rules led registrars to redact much of the personal contact data that used to appear in WHOIS. The shift continued through 2025, as registrars began moving from the old WHOIS protocol to its successor, RDAP, and a new ICANN policy further trimmed which contact fields are published by default. On top of that, most registrars offer a privacy or proxy service that replaces your details with the provider's. These changes help, but they control what is displayed, not what you entered: the address on the registration is still collected and stored, so it stays the variable that matters.
- Redaction: many registrars now hide personal contact fields in public WHOIS by default, though what is hidden can vary.
- Privacy or proxy services: these substitute the registrar's contact details for yours, sometimes free and sometimes paid.
- The gaps: coverage differs by domain extension, a paid service can lapse if it is not renewed, and some situations still surface the underlying data.

Why a Business Address Is the Durable Fix
A privacy service is a layer on top of whatever address you entered. If that layer is ever off, expired, or does not apply, the address underneath is what shows. That is the case for using a real business address as the underlying detail rather than your home.
Privacy service plus a safe underlying address
The strongest setup is both: keep a registrar privacy service on, and make sure the address underneath it is a business address you are comfortable being public, not your home. Then a lapse in the privacy service exposes a business address, not where you live.

Domain Privacy Is One Layer of a Bigger Picture
Your domain is not the only place a home address can leak. The same address often appears on your entity formation records, your business filings, and your mailing setup, so treating the domain in isolation only solves part of the problem.
For the entity-records side, see keeping your home address private during formation, and for how the different address roles fit together, the three business addresses every LLC needs.
Registering a domain can quietly put your home address in a public database, and a privacy service only masks whatever you entered underneath. Redaction and registrar privacy help, but they vary by domain type and can lapse, so they are not something to rely on alone.
The durable answer is to keep a privacy service on and make the underlying address a business address rather than your home. Then, whatever happens to the privacy layer, what is exposed is an address you chose to be public.
