How to Check Domain Registration Data with RDAP

RDAP helps you check important public registration data for a domain name.
You can use it to find the current registrar, domain status, expiration date, nameservers, DNSSEC information, and available abuse contact details.
If you own the domain, RDAP is useful for checking public data. But it does not replace your registrar account. To renew, unlock, transfer, update contacts, change nameservers, or request an AuthInfo / EPP code, you still need to log in to your registrar account.

Who Should Use RDAP?
RDAP is useful if you want to:

Check where a domain is registered
Confirm a domain expiration date
Prepare for a domain transfer
Check whether a domain is locked
Understand why a domain may not resolve
Review nameservers
Check DNSSEC information
Find registrar or abuse contact information

It is useful for domain owners, businesses, agencies, hosting providers, resellers, and domain investors.

What Can You Check with RDAP?
RDAP may show:

Registrar
Registry
Domain status codes
Registration date
Expiration date
Last updated date
Nameservers
DNSSEC information
Public contact data, if available
Redacted or privacy-protected fields
Registrar abuse contact

The information shown may vary by domain extension, registry, registrar, privacy setting, and policy.

Step 1: Enter the Exact Domain Name
Start with the correct domain name.
Check:

Correct spelling
Correct extension
No extra spaces
No https://
No page path
No unnecessary subdomain

For most registration checks, you only need the main registered domain.

Step 2: Use an RDAP Lookup Tool
Use an updated RDAP lookup tool that supports domain registration data.
Common options include:

ICANN Lookup
Registry RDAP lookup
Registrar lookup tools
Security or DNS investigation tools with RDAP support

For most users, a web-based lookup tool is easiest.
If one tool does not show enough information, try another trusted RDAP lookup source.

Step 3: Check the Registrar
The registrar is the company that manages the domain registration.
This helps you know:

Where the domain is registered
Where transfer-out usually starts
Where the domain lock may be managed
Where to request the AuthInfo / EPP code
Which registrar abuse contact may apply

Important: If you bought the domain through a reseller, RDAP may show the underlying accredited registrar instead of the reseller brand.
If you think the domain should be in your NiceNIC account but RDAP shows another registrar, check whether the transfer is still pending or whether the domain is actually managed elsewhere.

Step 4: Check Domain Status Codes
Status codes are one of the most important parts of RDAP.
Common examples include:

ok
clientTransferProhibited
serverTransferProhibited
clientHold
serverHold
pendingTransfer
redemptionPeriod
pendingDelete
inactive

These codes can explain why a domain:

Cannot transfer
Does not resolve
Is locked
Is on hold
Is expired
Is in redemption
Is pending deletion
Is restricted by the registrar or registry

If a transfer failed or the domain is not resolving, check the status codes before changing DNS settings.

Step 5: Check the Expiration Date
RDAP may show when the domain expires.
Use this to:

Avoid accidental expiration
Plan renewal
Prepare for transfer
Check whether the domain is expired
Manage client or portfolio domains

For important domains, do not wait until the last few days to renew or transfer.
If the domain is already in redemption or pending delete, contact support quickly.

Step 6: Check Nameservers
Nameservers show where DNS is managed.
This helps troubleshoot:

Website not loading
Email not working
DNS records not taking effect
Transfer planning
Old DNS provider issues
DNSSEC problems

If you added DNS records at one provider but RDAP shows nameservers from another provider, you may have updated DNS in the wrong place.

Step 7: Check DNSSEC
RDAP may show DNSSEC information, such as DS records, key tag, algorithm, or digest value.
DNSSEC can help protect DNS data integrity, but incorrect settings may cause resolution problems.
Check DNSSEC carefully if:

The domain shows SERVFAIL
The website or email does not resolve
Nameservers were recently changed
Old DS records may still exist
DNSSEC was enabled before a DNS migration

If you are not sure, review DNSSEC settings before making further DNS changes.

Step 8: Check Public Contact or Redacted Data
RDAP may show limited public contact information. It may also show words such as:

Redacted
Not disclosed
Data protected
Privacy protected
Proxy service

This does not automatically mean the domain is suspicious.
Public contact data may be hidden because of privacy settings, registration data policy, TLD rules, or privacy law handling.
If you own the domain, log in to your registrar account to check the full account-level contact information.

Step 9: Check Abuse Contact
RDAP may show the registrar abuse contact.
This contact is used for reports involving issues such as:

Phishing
Malware
Spam abuse
Botnet activity
Fake stores
Malicious redirects
DNS abuse
Compromised websites

Abuse contact is not the same as the domain owner contact.
If you need to report abuse, provide specific evidence, such as URLs, screenshots, timestamps, and technical details.

What RDAP Cannot Do
RDAP cannot:
Unlock a domain
Renew a domain
Transfer a domain
Change nameservers
Update contact details
Turn privacy on or off
Provide an AuthInfo / EPP code
For these actions, log in to the current registrar account or contact the authorized support channel.

FAQ
1. What is RDAP?
RDAP stands for Registration Data Access Protocol. It is used to check structured domain registration data.
2. Is RDAP the same as WHOIS?
No. WHOIS is the older lookup model. RDAP is the newer structured registration data lookup system.
3. What can I check with RDAP?
You may be able to check registrar, registry, status codes, nameservers, creation date, expiration date, updated date, DNSSEC data, and available contact or abuse information.
4. Does RDAP show the domain owner?
Sometimes it may show limited contact data, but many results are redacted or privacy protected.
5. Why is registrant information hidden?
It may be hidden because of privacy settings, registration data policy, privacy laws, TLD rules, or registrar data handling.
6. Can I use RDAP to get the EPP code?
No. RDAP does not provide AuthInfo / EPP codes. You must request the code through the current registrar account or authorized support process.
7. Can RDAP help with DNS troubleshooting?
Yes. RDAP can show nameservers and DNSSEC information, which can help identify where DNS is managed and whether DNSSEC may be involved.
8. Should I check my registrar account after RDAP?
Yes, if you own the domain. Your registrar account is where you manage contact details, privacy, renewal, locks, DNS, DNSSEC, and transfers.

Conclusion
RDAP is a useful way to check public domain registration data before transferring, renewing, or troubleshooting a domain.
Use it to review the registrar, status codes, expiration date, nameservers, DNSSEC, and available abuse information.
For domain management actions, log in to your registrar account.
