Additional LNP guidelines for the following service providers

LNP scenarios

In Japan, telephone numbers can be part of a group consisting of one parent (also known as main) number and one or more child numbers. The child numbers need to be listed in the LNP form.

The following scenarios are to be considered when submitting a port-in request:

ScenarioCommentWhat to expect?
Port in one or more child numbers and leave the parent numberSupported 
Port in only the parent numberSupported with a condition
  • Child numbers will be disconnected after the port is completed.
  • Not applicable for Unitalk/Dialpad or Otokuline/Otoku Hikari.
Port in the parent number with child number(s), where not all child numbers will be portedSupported with a condition
  • The remaining child numbers will be disconnected after the port is completed.
  • Not applicable for Unitalk/Dialpad or Otokuline/Otoku Hikari.
Port in group numbers: Requesting different LNP dates for the same group of numbersSupported with a condition
  • The rule of thumb is that all numbers in a group must be included in the same order and will be completed on the same date.
  • In cases where the order needs to be split into different dates as requested, it can only be done under the conditions below:
    • Parent/main number must be ported last.
    • Orders MUST be processed in a sequential manner or in batches (e.g., batch 2 cannot be processed until batch 1 porting order is completed).
    • The quantity of phone numbers per order (see table below) will be followed.
    • Standard lead times will apply per batch.
Port in child number with features (such as voice warp, AIS, etc.)NOT supportedRequest the current provider to remove the feature or Port all numbers in the group.
Port in group numbers: Requesting LNP for a group of numbers for the same dateSupported with a condition
  • Some donor carriers have a set cap to accommodate the volume of phone numbers per order (See the table below).
  • In cases where the group exceeds the quantity of numbers versus the capacity of the LNP system, the following steps are required.
    • The group must be split into batches to accommodate the system capacity.
    • Parent/main number must be ported last.
    • Orders MUST be processed in a sequential manner or in batches (e.g., batch 2 cannot be processed until batch 1 porting order is completed).
    • Standard lead times will apply per batch.

LNP lead times

Lead times to port phone numbers in Japan are 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 transfer, you may experience some loss of service to incoming calls during the port activation window while the numbers are being ported from the old carrier. Porting can take place sooner or later than the lead times and the porting activation window 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 5 business days. Status inquiry can only be requested on the 6th business 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.

Why is the quantity of phone numbers per order limited?

National LNP infrastructure is in its infant stage; thus, carriers are still working on improving individual systems. We are optimistic that the quantity will increase as the infrastructure matures.

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 Phone online account. One (1) working day after you successfully submit the LNP order, it will show as Pending Numbers. You will also receive notifications every 4 working days or as soon as relevant updates are available.

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

Yes, but this will set the order back to day 1. To amend (adding/removing numbers, change of LNP information) the LNP, the order is required to be canceled and submitted as a new LNP order, which will set the whole process back to day 1.

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

No. Expedites are not possible and are not industry-supported.

Why can't I schedule the cut-over date for the end of the month?

Carriers will need to update their records of all incoming and outgoing LNP transactions for inventory and traffic tracking purposes.

Can Zoom undo or reverse the completed LNP order?

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

What are Zoom’s LNP team's operating hours, and how can I contact them?

You can respond to the open LNP ticket (email thread). The Zoom porting team is a back-office team, and its 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 on a business day, between Monday through Friday, and have a fixed window time. 

Can I cancel my Port-In request?

Orders can only be canceled after the order receives a response. If the order already has a porting date, cancellation can only be requested 3 working days before the LNP date, except for the service providers stated here.

Can I reschedule my LNP date?

Yes, but this will require additional time. We will need to wait for the response to an ongoing order first; only then cancellation request be sent. A new order with the new LNP date will be submitted after the cancellation request is acknowledged.

Note: This sets back the porting process to day 1.

Why do I need to contact my provider if my order is denied?

Denial of the LNP application is normal and part of the process. Zoom will try to fix the reason for the denial without involving you. Zoom will only ask you to reach out to your service provider if the reason for denial is due to information mismatch, as we do not have authorization to get your information due to privacy.

What should I expect on the day of port?

For non-PEX/BYOC LNP, calls will start to work on your Zoom account anytime between the quoted porting window. You will be notified once the LNP order is completed, and the “Pending” Status will be removed.

I am porting my PEX/BYOC number, which is already in the Zoom portal. What do I need to expect?

Since the number is already in your account, it will remain as PEX/BYOC while the LNP is in progress. On the day of port, the phone number will be moved from PEX/BYOC to a Native number. The current setup, such as extensions or call flow, will remain the same.

Note: A loss of service to incoming calls is expected during the port activation window while the porting numbers are in progress, as backend configuration is required. Should you experience a loss of service, please immediately contact us through the existing LNP ticket.

I see the 0ABJ number in my online account, and it shows “Pending”. What will I do next?

The 0ABJ number that shows as Pending is normal. This means that the LNP order is 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 users. After the LNP completes, the configuration will automatically apply to the ported number.

Will my existing phone features with my current provider be ported as well?

No. Zoom only ports the phone number and will apply Zoom’s feature to the phone number.

Will Zoom cancel my service with my provider?

No. Our authorization is limited only to number porting. You will need to work with your provider to cancel your service.

Note: Please do this after LNP has been completed.

What should I do if my service provider is not included in the form?

It is possible that your service provider is a reseller and sources their provider from a wholesale carrier. Please contact your service provider and ask for the name of the donor carrier of your phone numbers.
