Frequently asked questions
What is E.164 format?
E.164 is the international standard that writes a number as a plus sign, the country code, then the national number with no spaces, like +11234567890. Most APIs expect it.
Does it handle an 11-digit number with a leading 1?
Yes. A US number that starts with the country code 1 is recognized, so 11234567890 formats as +1 (123) 456-7890 nationally.
What if I paste a non-US number?
Numbers that are not a standard US length fall back to a clean international style, grouping the digits after a plus sign so the value stays usable.
Are dashes, spaces, and parentheses removed?
Yes. Every non-digit character is stripped first, so any messy input is normalized before it is reformatted.
Is my data private?
Yes. Formatting runs entirely in your browser and nothing is uploaded or stored.
