General LNP guidelines

Note: Once the toll-free number porting process starts, changing the porting dates and window or cancellation is no longer possible.

LNP lead time

Lead time to port toll-free numbers in Japan is dependent on the regulatory requirements and the responsiveness of the suppliers in the chain. The process is also reliant on the accuracy of the information provided. We will always keep you advised as the order progresses.

Note: On the day of the transfer, you may experience some loss of service to incoming calls during the activation window. Porting can take place sooner or later than the lead times quoted.

LNP frequently asked questions

How long until we receive an update from the carrier after the order submission?

A response may take up to 10 working days. Status inquiries can only be requested on the 11th working day from the submission date.

Why will it take so long to complete my LNP order?

The LNP lead time is dictated by the business rules of each donor carrier within the framework of government regulation. LNP lead time is based on the complexity of the port request. Your current service provider may require a greater level of validation and back-office work related to your LNP order. Zoom strives to get a response from the losing service provider with enough time for our customers to prepare for the day of LNP activation, and the lead time indicated allows us to accomplish a schedule that accounts for our customers’ needs.

How do I check the status of my current LNP order?

You will see the status of your phone number in the unassigned tab of your Zoom online account one (1) working day after you successfully submit the LNP order. The number will appear as “Pending” in your Zoom account portal. You will also receive notifications every 4 working days or as soon as relevant updates are available.

I see the Toll-Free number in my online account, and it shows “Pending.” What will I do next?

A toll-free number that shows as “Pending” is normal. This means that the LNP Order is now in progress. To minimize the downtime on the day of port, you must configure your call flow and assign the number to port to any queue or user. After the LNP is completed, the configuration will automatically apply to the ported number.

Can we add or remove numbers to an existing LNP order?

No. Cancellation of the order is not possible; therefore, removing the toll-free number from the list is impossible. Adding a phone number is also not possible, you will be required to fill out the Portability Form and submit a separate LNP order.

My order already has an LNP cut-over date. Can we move it to an earlier date?

No. Once the LNP process starts, changing of dates is not possible, as toll-free number porting is 100% manual.

Why can't I change the date or cancel my order?

Toll-free porting is 100% manual. The process requires physical work on both winning and losing carriers from providing a physical copy of the form, provisioning of the network, and mapping the toll-free to a terminating number. Once the LNP order starts, the forms cannot be modified, and the order cannot be cancelled.

Can Zoom undo or reverse the completed LNP order?

No. LNP reversal is not supported. You need to contact your old service provider to start the LNP process, going back to their system.

What are Zoom’s LNP team operating hours?

The Zoom porting team's operating hours are from 9 AM – 6 PM local time, closed on weekends and holidays.

Can I request a weekend, outside business hours, or holiday LNP date/time?

No. Donor carriers only support LNP Cut-over dates between Monday through Friday, and the window time is followed as selected in the form.

What should I expect on the day of port?

The switch will happen between the selected window times. Calls will start to work on your Zoom account anytime between the selected windows. You will be notified once the LNP order is completed, and the “Pending” status in the toll-free will be removed.
