Philippines phone number validator
How the phone number format works
- Format
- Philippines phone number in national or international (+63) format
- Example
- +639051234567
Things to watch for
- Accepts national or international (E.164, e.g. +63...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Philippine phone number is easiest to spot by its mobile prefix: 09 followed by a 2-digit network code and 7 more digits, e.g. 0917 123 4567 — 11 digits total including the trunk 0. Landlines are less uniform: Metro Manila uses the single-digit area code 2 plus a 7-digit number, while provincial area codes run 2 digits with a shorter local number attached.
How this validator works
Enter the number nationally (09171234567) or with the country code (+639171234567); this tool checks digit count and prefix range against the Philippines’ real numbering plan using Google’s libphonenumber, entirely in your browser. Converting to +63 form always drops the leading trunk 0, leaving exactly 10 digits behind it — a mobile number with 11 digits after +63, or the 0 kept in place, is a clear sign of a mistyped entry.
What a pass doesn’t tell you
A pass confirms the digits match a real Philippine mobile or landline pattern — it says nothing about whether that SIM currently has an active plan or the landline is connected. Prepaid mobile numbers in the Philippines are recycled by carriers after periods of inactivity, and format validation alone can’t detect that.
Scope: use this to catch a missing digit, an extra digit, or a kept trunk 0 after +63 before a number reaches a form or SMS gateway — not as proof the SIM is currently loaded.

phone number FAQ
What happens to the leading 0 in a Philippine mobile number when converting to +63?
It's dropped. The 0 in 0917 123 4567 is a national trunk prefix, so the international form is +639171234567 — the remaining 10 digits (917 123 4567) are what actually identify the line.
How long is a Philippine landline number?
It depends on the area code: Metro Manila uses a single-digit code (2) followed by a 7-digit number, while other regions use 2-digit area codes with shorter local numbers — so total length varies by region, unlike the fixed 10-digit mobile format.
Does a valid Philippine number check confirm the SIM is active?
No. It only confirms the digits match a real Philippine mobile or landline pattern — it can't confirm a prepaid SIM is loaded or a landline connected, since that requires a carrier lookup outside what a format check can do.
