Restrictions on 0ABJ numbers for new orders and porting orders

Currently, Japan allows number portability for 0ABJ numbers, but this service is limited exclusively to Nippon Telegraph and Telephone Corporation (NTT)-owned numbers. As it stands, only NTT numbers can be ported, while all other 0ABJ numbers remain non-portable. However, there will be significant changes; starting from January 20, 2025, 0ABJ numbers will become portable across all service providers.

To facilitate these upcoming changes and enhance the porting systems, all carriers in Japan will observe an embargo period between December 2024 and January 2025 (the exact duration may vary by operator). Zoom will have operational restrictions from November 30, 2024, to January 19, 2025. This will affect new orders, porting orders, and execution of porting.

New requests for adding numbers in certain cities will not be processed from December 24, 2024, to January 13, 2025. This pause will depend on whether Zoom has an available inventory of preactivated numbers for specific cities. The additional requests that remain unprocessed during the restriction period will be addressed after January 13, 2025.

Porting orders will be suspended during the entire restriction period, and those accepted before November 30, 2024, will have execution restrictions from December 24, 2024, to January 13, 2025.
