How the Phone Parser and Formatter Works

Phone numbers come in many formats (spaces, dashes, parentheses, local formats). This tool normalizes that input and produces standardized formats that are easier to store and share.

Pick a default country code for local numbers, then paste a phone number. The tool parses it, checks if it’s valid/possible, and outputs E.164, international, and national formats.

  1. Default country: Helps interpret local numbers without a +country code.
  2. E.164 output: Best for databases, CRMs, APIs, and verification flows.
  3. International / national: Best for display and copy/paste across regions.
  4. Valid vs possible: Two useful checks to reduce bad form submissions.

When to Use E.164 vs International Format

Use E.164 when you store phone numbers or send them to an API (auth, SMS, CRM integrations). Use international format when you display numbers to humans across countries.

  1. Store numbers: Use E.164 for consistency and fewer edge cases.
  2. Show numbers: Use international format for readability across regions.
  3. Local display: Use national format when you only operate in one country.

FAQ

What is E.164 format?

E.164 is the global phone number standard used for storing numbers internationally. It starts with a + followed by the country calling code and the national number (for example, +14155552671).

Why do I need a default country code?

Local numbers often don’t include a +country code. Selecting a default country tells the parser how to interpret numbers like 0612345678 correctly.

What’s the difference between “valid” and “possible”?

“Possible” means the number has a plausible length/structure. “Valid” means it matches known numbering rules for that country (stronger check).

Does this tool upload or store phone numbers?

No. Everything runs locally in your browser. Your input is not uploaded, stored, or shared.

Does it support every country?

Yes — the country selector includes all real ISO country codes supported by the phone number library, and formatting works for each of them.
