Phone number formatter: validate and convert any list to E.164

E.164 is the international standard for phone numbers: a plus sign, the country code, then the national number, with no spaces or punctuation and at most 15 digits. +14155552671 is a US number in E.164. Most CRMs, calling tools and APIs store numbers this way, because it reads the same everywhere.

Paste the column here (or import the CSV), pick the default country for numbers written without a country code, and keep E.164 selected. Then copy the valid numbers or download the CSV, which keeps your original input next to each result.

Yes, for most countries: each range of numbers is assigned a line type in the national numbering plan, and the tool reads it. The exception is the US and Canada, where mobiles and landlines share ranges: those numbers show as “Landline or mobile”.

No. The tool checks that a number is well formed and belongs to an allocated range, without calling it or querying an operator. A valid number can still be disconnected or belong to someone else. To get a verified direct number, use Enrow's Direct Phone Finder.

No. Formatting runs entirely in your browser. The numbers you paste or import are never sent to Enrow or anyone else, and they're gone when you close the page.

It's free, with no sign-up and no limit. Lists of several thousand numbers work: the table shows the first 500 rows, and the copy and the CSV include all of them.
