Transfer Timeline and Approval Process

Which two registries sit on either end of an inter-RIR transfer decides more of the timeline than anything else. Documentation completeness and pre-approval status account for most of what remains, and both are within the applicant's control before the request is ever filed.

Policy snapshot last reviewed May 2026. Official policy references: RIPE NCC Transfers, ARIN Transfers (NRPM 8.3 / 8.4), APNIC Transfers, LACNIC Inter-regional IPv4 Transfers. Always confirm details with the relevant RIR before initiating a transfer.

Timeline Overview by RIR Combination

Inter-RIR transfer timelines range from 4 weeks to 10 months depending on the registries involved and various other factors.

Timeline ranges below reflect observed transfer durations through 2025 and Q1 2026, based on Via-Registry case data and public RIR statistics (NRO, RIPE inter-RIR statistics). Actual durations vary with documentation quality and RIR workload.

Fast Processing Combinations (4-6 Weeks)

RIPE NCC -> ARIN:

• Typical duration: 4-6 weeks
• Well-established procedures
• Pre-approval available at ARIN
• Efficient coordination between RIRs
• High volume of transfers = streamlined processes

RIPE NCC -> APNIC:

• Typical duration: 4-6 weeks
• Mature inter-RIR relationship
• Regular coordination channels
• Efficient documentation processing
• Similar policy frameworks

ARIN -> APNIC:

• Typical duration: 4-6 weeks
• Compatible needs-based policies
• Established transfer procedures
• Good inter-RIR communication
• Time zone differences managed well

Moderate Processing (6-10 Weeks)

RIPE NCC -> LACNIC:

• Typical duration: 6-8 weeks
• LACNIC requires more detailed justification
• Additional documentation review
• Language considerations (Spanish/Portuguese)
• Less frequent transfers = longer processing

ARIN -> LACNIC:

• Typical duration: 6-8 weeks
• Coordination between distant time zones
• LACNIC's detailed policy requirements
• More stringent needs assessment
• Potential translation needs

APNIC -> LACNIC:

• Typical duration: 8-10 weeks
• Less common transfer route
• Maximum time zone difference
• Coordination challenges
• Additional policy verification

Extended Processing (2-10 Months)

LACNIC as primary registry: When LACNIC is heavily involved (especially as recipient), timelines can extend significantly:

• Minimum: 2 months
• Maximum: 10 months
• Average: 3-5 months

Factors causing LACNIC delays:

• More rigorous needs assessment
• Extensive documentation requirements
• Translation needs (English ? Spanish/Portuguese)
• Smaller staff for inter-RIR processing
• Less automation in processes
• NAT deployment verification historically required
