Eight-digit Number Format for Landlines and DUO FAQs

What is the NTC Memorandum Circular 4-07-2018 about?

The directive by the National Telecommunications Commission (NTC) ordering all telecommunications companies in the Philippines to migrate all telephone numbers with "02" area code from the existing 7-digit format to an 8-digit format has been deferred to October 6, 2019.


This is to give local banks and credit card companies ample time prepare for the change. The date for the migration was initially set on March 18, 2019.

Are all telecommunications companies in the Philippines complying with the new directive?

All telecommunications companies in the Philippines are covered by the NTC directive.

Which customers are affected by the memorandum? Will this affect my number if I'm outside the (02) area code?

The NTC memorandum circular applies to all telephone numbers within the specified area code “02.”


Customers outside these (02) area codes aren't covered by the NTC memo and will continue to use their existing 7-digit number format.

Why are we migrating to an 8-digit numbering format for telephone numbers within the (02) area code?

This is to address the insufficient number of assignable exchange codes.

What is a Public Telecommunications Entity (PTE) identifier?

A Public Telecommunication Entity (PTE) identifier is a prefix assigned by the NTC to a particular telco/service provider to preserve order and quickly identify to which company a number belongs.


NTC has assigned the following Public Telecommunications Entity (PTE) identifiers:


Identifier Company
3000-YYYY to 3499-YYYYBayan Telecommunications, Inc.
7XXX-YYYYGlobe Telecom, Inc/Innove Comm Inc.
5300-YYYY to 5799-YYYYETPI/Telecomm Tech Phils Inc.

When will the migration to an 8-digit number format happen?

The scheduled migration as agreed amongst NTC and the telecom providers is set on October 6, 2019, from 12:01 AM - 5 AM.

What will happen during the migration? What services will be affected?

On October 6, 2019, from 12:01 AM - 5 AM, all telephone numbers with 02 area code, including DUO, will experience a service interruption in their incoming and outgoing calls.


Specifically, the voice services for landline, voice over IP (Internet Protocol), Super Home Phone, DUO and emergency numbers will be affected during this period.

How will Globe inform their customers of this change?

Globe will continue to make use of the following channels - hotline, social media, media announcements, email, and text - to generate an awareness campaign  to the general public at least 3 months before the migration.

Will # number services be affected? What about international/domestic toll-free services?

During the activity on October 6, 2019, from 12:01 AM -5 AM, your #XXXXX will experience a service interruption anytime from 12 AM - 5 AM. After the activity, your #Number will retain its current dialing pattern


Ex. #87000 after October 6, 2019 will still be #87000.


The same goes for all international/domestic toll-freenumbers using 1800-xxx as its dialing pattern.

Would there be any changes that need to be made on our PABX System when this is implemented?

Yes, there is, depending on the type of PABX configuration.


  • For ANI-masking configuration, there will be no change needed in your PABX.
  • For ANI-filtering configuration, ANI should be changed from 7-digits to 8-digits. It is best to get in touch with your account manager to identify the specific change needed in your PABX.

My old number is in my business cards, flyers, marketing materials. How will I inform my customers/friends about the new number?

The new number will be implemented on October 6, 2019. We're informing you ahead of time so you can update your contact materials in time for the change and inform those within your personal and professional circle accordingly. Also, starting October 6, 2019 until January 5, 2020 - a period of three months - those who will call your old number will be able to hear an in-call voice recording on how to properly get in touch with you.

Will this affect my "special/golden" number?

Since this is a government mandate, all "golden and special" numbers in the (02) area code will follow the new number format.

I want to complain about this government mandate, where can I send my formal complaint?

This mandate was given by the National Telecommunications Commission, any complaints regarding this can be emailed to them directly at [email protected].
