Why Do Some Mobile Prefixes in the Philippines Work on Multiple Networks?

I’ve noticed that in the Philippines, some mobile number prefixes seem to work on multiple networks. For example, a number starting with a specific prefix might be originally from one telecom provider but is now active on another. This can make it confusing to determine which network a number belongs to.

Is this due to mobile number portability (MNP) or are there other reasons why prefixes aren’t always tied to a single telecom provider? How do networks in the Philippines handle this, and is there an easy way to check the correct network for a number?"*

  • This is an interesting question! In the Philippines, the reason why some mobile prefixes seem to work on multiple networks is due to Mobile Number Portability (MNP). This allows users to switch from one network to another without changing their number, making it difficult to determine the original network based on prefix alone.

    Another reason is that telecom providers sometimes lease or acquire number ranges, leading to cases where a prefix once exclusive to a specific network is now shared or reassigned.

    For those who frequently need to check which network a number belongs to, there are online tools available that can help. One such website is Whatnetwork, which provides a quick way to determine the correct network for any mobile number in the Philippines.

    Hope this helps! Has anyone else noticed prefixes that seem to belong to more than one carrier?

  • Yes, that’s correct — it’s mainly due to Mobile Number Portability (MNP). Since the Philippines implemented MNP, users can switch telecom providers without changing their mobile numbers, including the prefix. This means a number that starts with a prefix like 0976 What Network Philippines originally tied to, say, Globe, might now be active on Smart or DITO.

  • I did a bit of digging after posting this and it seems the main reason is Mobile Number Portability (MNP). With MNP, users in the Philippines can keep their old number even if they switch networks, which explains why some prefixes don’t always match the actual provider anymore. Originally, prefixes were tied directly to Globe, Smart, etc., but now it’s more about routing on the backend rather than what the digits at the start say.

    It actually reminded me of something deeper — just like prefixes don’t always reveal the “real” network, the labels we carry in life (job, role, title) don’t always reveal our true self either. Sometimes you need to look beyond the surface to understand what’s really there. That thought led me into exploring more on spirituality, and I found this resource insightful: spiritual meaningz
