Requesting ASN (Autonomous System Number)



To request an ASN organization should fill up the template indicated above and then sent it to . Once it is verified and no error was found, an e-mail is sent back with the "ticket" number that identifies this request in our system.

After being approved, it will be necessary to pay the registration fee and sign the Registration Service Agreement. The instruction for payment and about the agreement is sent with the approval message. The ASN allocation is only done after the payment and the reception of the agreement already signed.

LACNIC shall allocate Autonomous System Numbers to those organizations that meet the following requirements:

  1. The organization must have the need to interconnect with other independent Autonomous Systems at the time of the application, or be planning to interconnect within a period of no more than six (6) month as of the moment of the application. After this period, LACNIC may revoke the assigned ASN if it has not been used.

  2. Detail the applicant's routing policy, specifying the ASNs with which the organization will interconnect and the IP addresses that will be announced through the requested ASN.

From January 1, 2007 to December 31, 2010 Lacnic assigned ASN of 16 and 32bits upon request. However, since January 1, 2011 Lacnic stopped making distinctions between the assignment of 16- and 32-bit Autonomous Systems Numbers (ASNs) and will only assign ASNs from a general 32-bit pool. This change will be introduced to comply with the Global Policy "Internet Assigned Numbers Authority (IANA) Policy for Allocation of ASN Blocks to Regional Internet Registries" adopted in September 2010.
