How to use the Phone Number Formatter

  1. Choose the country.
  2. Paste numbers in any format, one per line.
  3. Pick E.164, international or national format and copy the result.

What does this tool do?

Phone numbers arrive in every shape: (415) 555-0132, 415.555.0132, +1 415 555 0132. E.164 (+14155550132) is the format most apps, CRMs and SMS services expect.

The formatter strips punctuation, handles the country code and trunk prefix (the leading 0 in many countries) and checks the length. Everything runs in your browser — your text is never uploaded.

Why use it?

  • Bulk formatting.
  • E.164 for apps and CRMs.
  • Flags wrong lengths.

Accuracy and limits

  • Checks length and country code only — it can't confirm that a number exists or is in service.

Privacy

The calculation happens instantly in your browser. The numbers you enter are not sent to our servers or saved. There's no account to create and nothing to install.
