How a Philippine mobile number is built
Every Philippine mobile number has 11 digits when written locally: 0 (the domestic trunk prefix), then a three-digit network code, then a seven-digit subscriber number. Writers usually group it as 09XX XXX XXXX. The first four digits — for example 0917 or 0933 — are what people call the “prefix”.
Internationally you drop the leading zero and add the country code +63, so 0917 123 4567 becomes +63 917 123 4567 (or +639171234567 without spaces, the E.164 format that apps and SMS gateways expect). A newer range starting 08 also exists: 0813, 0817 and DITO's 0895–0898.
The networks behind the prefixes
Three mobile network operators run their own infrastructure in the Philippines: Globe Telecom, Smart Communications (a PLDT subsidiary) and DITO Telecommunity, which launched commercially in March 2021. Several consumer brands sit on top of them:
- TM and GOMO run on Globe.
- TNT (Talk 'N Text) and Sun Cellular run on Smart. Sun was a separate operator until it was absorbed into the Smart group, but its prefixes are still widely called “Sun numbers”.
- Smaller labels such as Cherry Prepaid have used Globe's network.
Prefix lists by network
These are the original allocations most commonly cited in public lists. Use the searchable prefix directory for the full table with international formats.
| Network | Prefixes |
|---|---|
| Globe / TM | 0817, 0904–0906, 0915–0917, 0926, 0927, 0935–0937, 0945, 0953–0956, 0965–0967, 0975–0979, 0995–0997 |
| Smart / TNT | 0813, 0907–0914, 0918–0921, 0928–0930, 0938, 0939, 0946–0951, 0961, 0963, 0968–0970, 0981, 0989, 0998, 0999 |
| Sun (Smart group) | 0922–0925, 0931–0934, 0940–0944, 0973, 0974 |
| DITO | 0895–0898, 0991–0994 |
So what is 0933? It is a Sun Cellular prefix, part of the Smart group — which makes this site's name, 093333, look like the start of a Sun number in the Philippines. (In Vietnam the same digits point to MobiFone; see the Vietnam guide.)
Portability: why prefixes are now hints, not facts
The Mobile Number Portability Act (Republic Act 11202) lets subscribers move between Globe, Smart and DITO without changing their number. A 0917 number that started on Globe may be on DITO today. For individuals the impact is small — most promos and pricing are now network-neutral — but for businesses it matters: routing SMS by prefix alone can send traffic down a more expensive or less reliable path. High-volume senders use a live lookup (often called an HLR or MNP query) before sending.
Practical uses (and limits)
- Sanity-check a caller. A “bank” calling from a personal 09 number is a red flag regardless of network. Real institutions use hotlines and registered sender names.
- Validate data. A Philippine mobile must be 11 digits starting 09 or 08 (or +639/+638 internationally). Anything else is a typo or a fake.
- Plan budgets. Group your contact list by original network with the bulk sorter to estimate SMS costs.
What a prefix can never tell you is who owns a number. SIM-registration data is held by the operators under the SIM Registration Act and data-privacy rules; any site claiming to reveal a stranger's name and address from a number should be treated with suspicion.
