Submitting a Transfer Pre-approval Request

ARIN only offers pre-approvals to organizations seeking IPv4 address space via a Transfer to Specified Recipients (NRPM 8.3) based on a 24-month projected need. Before requesting a transfer pre-approval, please review ARIN's policies to ensure that you qualify to receive IPv4 addresses. Please refer to the ARIN Number Resource Policy Manual (NRPM) for full details.

Note: Pre-approval requests will be reviewed based on the organization's projected 24-month need and will not be subject to re-verification for an 8.3 transfer submitted within 24 months of this approval.

To request pre-approval for a transfer:

  • Log into your ARIN Online account
  • Select Transfer Resources on the left
  • Answer the questions on the form provided
  • Follow the instructions on the subsequent screens, including justification information for the space you would like pre-approval for
  • Submit your request to ARIN for review

Note: All transfer pre-approval requests require an ARIN Online account linked to either an Admin or Tech Point of Contact record (POC) with the authority to request resources for a valid Organization Identifier (Org ID).


We will verify receipt of your request upon successful submission. We will issue you a ticket number as soon as you successfully submit the request.

Review Process

We will respond to requests within two business days. We may request additional information; these requests will be sent to your ARIN Online Message Center. For each question and response cycle, we will respond within two days. If you do not reply within 90 days, the ticket will be closed. A request for additional information does not imply a request denial.

For questions about pending requests, send a reply to the ticket through ARIN Online, or call ARIN's Registration Services Help Desk at +1.703.227.0660. When you call, have your ticket number and any requested documentation available and have access to the ARIN website. For further follow-up, supply the name of the ARIN Resource Analyst who assisted you on your prior call.

Request Approval

ARIN notifies the submitter of pre-approval via the submitter's ARIN Online account. The pre-approval is valid for two years.

If a request is rejected and you feel proper justifications were met, contact ARIN using Ask ARIN or via email at for further explanation.

Note: For organizations that are requesting pre-approval for the transfer of IPv4 resources via Transfer to Specified Recipients (NRPM 8.3), ARIN will request that the submitter review all data received on the request with an officer of the company and have the officer sign an officer attestation certifying the accuracy of the data submitted.

If you have any questions regarding officer attestation, notify Registration Services using the Ask ARIN feature in your ARIN Online account. Alternatively, you may contact for further explanation.

What Next?

Once a transfer is arranged, the organization that has the available IPv4 addresses should submit a Transfer to Specified Recipients (NRPM 8.3). For full details, see ARIN's Transfer Resources page.
