Dial Builder

Paste any messy phone number (spaces, dashes, parentheses). We’ll normalize it and output: +E.164 (mobile-friendly) and a legacy format (exit code + country code + national number).

What’s this? (What does “+” mean?)

The + symbol means: “use my country’s international access code automatically”. Most phones understand +, so +E.164 is the most universal way to write an international number.

Australia’s international access code is 0011
UK: 00
US/Canada: 011

Example: +44 115 877 3466 is the same as 0011 44 115 877 3466 when calling from Australia.

Number normalizer

The same number normalizer powers this builder. If your number starts with +, we treat it as international and just normalize formatting. Otherwise we treat it as a national number for the destination and (when configured) drop the trunk prefix.

FAQ

What does the “+” mean in a phone number?

The “+” means “use my country's international access code automatically”. On mobiles, + is the most universal way to write an international number (E.164).

Do I keep the leading 0 when calling internationally?

Often no. In many countries the leading 0 is a domestic trunk prefix and is usually dropped when you dial internationally. This tool will warn you and (when configured) drop the trunk prefix for the destination country.

What's the difference between the mobile-friendly and legacy formats?

Mobile-friendly uses +E.164 (e.g. +44...). Legacy uses your exit code (IDD prefix) + country calling code + national number (e.g. 011 44 ...).
