ARIN Membership

Becoming a Member

Your organization may become an ARIN Member by:

  • enrolling in ARIN's Registration Services Plan - this is automatic for Internet Service Providers (ISPs); or
  • applying for ARIN Membership and paying a $500 annual fee.
  • Applying for membership is an option if your organization:

  • holds Internet number resources from ARIN (an Autonomous System Number and/or IPv4 or IPv6 assignment) under a signed Registration Services Agreement (RSA); or
  • has signed a Legacy Registration Services Agreement (LRSA).
  • Applying for Membership

    If your organization is not automatically enrolled in the Registration Services Plan, you may apply for membership by performing these steps:

  1. Log in to your ARIN Online account.
  2. Select Your Account > Organization Identifiers from the navigation menu.
  3. Select the Organization Identifier (Org ID) that you wish to register as a member.
  4. In the Org section, choose Actions and select Membership. (This menu option appears only if your organization is eligible for membership.)
  5. Complete the form and submit it to ARIN for review.

Note: This feature requires you to have an ARIN Online account that is linked to an Org ID, and your role in the organization must be one of the following: an Administrative Point of Contact (POC), Tech POC, or Billing Contact. Visit the Introduction to ARIN's Database page to learn more about the different types of POCs.

Membership Renewal

Note: This section only applies to organizations who have applied separately for membership. It does not apply to ISPs, whose membership is automatically renewed as long as resources are not transferred or returned to ARIN.

Annual $500 renewal invoices will be sent to the Billing POC for the member organization. For information about how to pay this fee, click here.
