Help! I can’t access the Verisign Customer Center.

The Verisign Customer Center is an online portal for partners to find technical details on implementation, including SDKs. Access to this portal is subject to NameStore credentials and access restrictions. If you are unable to connect to the Verisign Customer Center, please email customer support.

Help! My domain name expired.

Verisign operates several domain name registries; however, we are not a registrar. If your domain name expired, you need to contact your registrar about renewing. If you don’t know who your registrar is, you may search the Whois database for your domain name. The results will show the registrar responsible for registering your domain name so that you can contact them.

How do I become a registrar?

To become a registrar, you’ll need to go through a certification process. Different top-level domains (TLDs) have different requirements and processes and some TLDs require ICANN accreditation. Get all the details about certification for Verisign supported gTLDs in our Become a Registrar section.

What are these new generic top-level domains I’ve been hearing about?

With the ICANN New gTLD Program, the number of top-level domains (TLDs) will grow to nearly 2000. Verisign applied for 14 new gTLDs and has been selected to serve as the Back End Registry Services (BERS) provider for approximately 200 other new gTLDs that have or will launch in the near future. Learn more about new gTLDs.

How do I register an Internationalized Domain Name (IDN)?

If you own a website or provide other Internet-based services and would like to use Internationalized Domain Names (IDNs) to help your customers, you may register an IDN in available characters through participating ICANN-accredited and Verisign-certified registrars. A registrant requests an IDN from a registrar that supports IDNs. The registrar converts the local language characters into a sequence of supported characters using ASCII-compatible encoding (ACE). The registrar submits the ACE string to the Verisign® Shared Registration System (SRS) where it is verified and encoded. The IDN is added to the appropriate TLD zone files and propagated across the Internet. Find a Registrar.

Where do I get my password for the DDoS Protection Services User Portal?

How do I know if I’m experiencing a DDoS attack?

A denial of service (DoS) attack occurs when traffic is sent from one host to another computer with the intent of disrupting an online application or service. A distributed denial of service (DDoS) attack occurs when multiple hosts (such as compromised PCs that are part of a “botnet”) are used to carry out and amplify an attack. Attackers usually create the denial-of-service condition by either consuming server bandwidth or impairing the server itself. Typical targets include Web servers, DNS servers, application servers, routers, firewalls and Internet bandwidth.
