There is a series of numbers that serves as an identification name tag in all Philippine cellular numbers. It is not random. It is an electronic signature that tells us what company was initially holding and using this number. They are called mobile prefixes.
In this 2025 guide, we’re talking about what network the 0919 prefix is, Smart or TNT, why prefixes are still a thing today and how to check if a number with 0919 is still from the same network.
What Is a Mobile Prefix?
A mobile prefix is the four numbers that come right after the zero of a Philippine mobile number.
Example:
The prefix of the number 09191234567 is 0919.
Prefixes are assigned to mobile operators such as Smart, Globe, TNT, or DITO by the National Telecommunications Commission or NTC.
They oversee the telecommunications sector and determine where a number came from.
What Network Is 0919?
The 0919 prefix belongs to Philippine telecommunications giant Smart Communications.
It is also under its subsidiary Talk ‘N Text (TNT).
So if you buy a number with the 0919 prefix, you can be sure that it was initially released by Smart or TNT, unless the owner has availed of Mobile Number Portability (MNP) to switch network without switching numbers.

Why Prefixes Like 0919 Are Still Handy
Even as of 2025 when nearly all promos are “all-network,” prefixes are still handy and helpful.
Here’s why:
- Don’t Send Load to the Wrong Network
Once you’ve sent the load already, there’s no turning back. Fortunately, 0919 is Smart or TNT so you won’t accidentally send load to a Globe or DITO number.
- Buy the Right Promo
Same-networkers still enjoy trouble-free call and text promos.
Since you already recognize that 0919 is Smart/TNT, you do not miss out on any within-network free or discounted call and text.
- Interstitial Charge Savings
Cross-network calls and texts remain your cost.
Since you would know that your friend’s number begins with 0919, you would know what offer or promotion to apply in order to save.
- Business and Marketing Convenience
Prefix listing of client numbers is utilized by organizations for spend tracking, promoting, or reaching for SMS promotion.
In case you know 0919 = Smart, then you can segment the same.
- Makes Scam Awareness Increase
A prefix provides you with an immediate idea from where a call or message is originating.
If you’re not logged online in Smart/TNT and you’re being called by 0919, you would have to be careful.
