Maybe you want to know whether a number is TNT before using a same-network promo. Maybe you just forgot your own number. This guide gives you the prefix list, the right formats, every reliable way to find your number, and what to know about recycled and ported numbers.

How TNT SIM Numbers Are Formatted

Dialing from	Format	Example
Inside the Philippines	09XX XXX XXXX (11 digits)	0918 123 4567
From abroad	+63 9XX XXX XXXX (10 digits after +63)	+63 918 123 4567
Some online forms	9XX XXX XXXX (10 digits, no 0)	918 123 4567

The last row trips people up. Some forms want the leading 0 and others don’t, so follow the hint in the box. The digits after the 0 or +63 never change.

When you save a contact, store it as +63 9XX…. That format works whether you’re in Manila or overseas.

TNT and Smart Prefix List

TNT is a Smart brand, and both share one block of prefixes. The number alone doesn’t tell you whether it’s TNT or Smart. That depends on which SIM pack was sold.

Prefixes commonly listed for TNT:

• 0907, 0909, 0910, 0912
• 0930, 0938
• 0946, 0948
• 0950

Other prefixes in the Smart/TNT block (they can be either brand):

• 0908, 0911, 0913, 0914, 0918, 0919, 0920, 0921, 0928, 0929, 0939, 0947, 0949, 0951
• 0961, 0963, 0968, 0969, 0970, 0981, 0985, 0989, 0998, 0999
• 0813

Some former Sun Cellular prefixes now sit under Smart as well.

Globe and DITO Prefixes, for Comparison

If a prefix isn’t on the list above, it may belong to another network. Commonly listed blocks include:

• Globe / TM / GOMO: 0905, 0906, 0915, 0916, 0917, 0926, 0927, 0935, 0936, 0937, 0945, 0953–0959, 0965–0967, 0975–0979, 0995–0997, 0817
• DITO: 0895–0898, 0991–0994

Use these only as a rough guide. They come from the same unofficial trackers, and porting moves numbers between networks.

Why a Prefix Isn’t Proof

Two things break the “prefix = network” rule:

1. Mobile Number Portability (MNP). Under RA 11202, you can move your number to another network and keep it. A 0917 (Globe) number may be on TNT now, and a 0907 may be on Globe or DITO.
2. Shared blocks. Smart, TNT and the old Sun prefixes all sit under one company, so a prefix can’t tell them apart.

If it matters, for example for a same-network promo, ask the person or check the network name on their texts.

How to Find Your Own TNT Number

Forgot your number? Try these, starting with the easiest:

Getting a New TNT Number

New numbers come with new SIMs. Buy a physical SIM or an eSIM from a Smart Store or the Smart Online Store. Our eSIM setup guide covers the digital option.

Every new number must be registered before it works. Follow our step-by-step registration guide.

You usually can’t choose a specific “vanity” number at a store.

Keeping Your Number: Replacement, eSIM and Porting

Your number can outlive the SIM card they came on:

Situation	What to do	Same number?	Cost
SIM lost or damaged	Get a replacement at a Smart Store with your ID	Yes	Ask at the store
Move to eSIM (“tnt esim same number”)	Upgrade at a Smart Store or through MySmart	Yes	₱89
Come from Globe/DITO	Port through MNP with a USC code	Yes	Free
Number disconnected	Buy a new SIM	No	New SIM price

The USC (Unique Subscriber Code) is a 9-digit code from your current network, valid for 15 days, according to TNT’s MNP page.

Recycled Numbers

TNT’s terms say permanently disconnected numbers can be reissued 180 days after disconnection. So a “new” number may have belonged to someone else, and you might get their old texts or OTPs.

If that happens:

• Update the number on your own bank, GCash, Maya and social accounts.
• Ignore OTPs meant for the old owner, and never use them.
• If an app says the number is “already linked,” contact that app’s support, not TNT. TNT’s terms say it can’t change third-party accounts.

To keep your own number from being recycled, keep it loaded. TNT’s terms say a SIM at zero load for 120 days in a row is permanently disconnected. Need help? See our full list of help channels.
