What does a Chile phone number look like?

9 digits: mobiles start with 9, Santiago landlines with 2. Landlines are written +56 2 XXXX XXXX and mobiles +56 9 XXXX XXXX. In full international (E.164) format a Chile mobile is written +56981234567: the country code +56, and no spaces or punctuation.
The anatomy of a Chile phone number under ITU-T E.164: country calling code 56, then the national destination code, then the subscriber number, to a maximum of fifteen digits after the plus. Nationally a Chile number is written +56 2 XXXX XXXX; in E.164 the prefix and the spacing both come off.
National formatting is for people. E.164 is for databases, APIs, and caller ID — store Chile numbers in the right-hand form.

A quirk of Chile numbering

Chile shifts its clocks on a schedule of its own. Verify the current offset before booking a call window.

Validation

How to validate a Chile number

Validating a phone number is three separate checks, and conflating them is the usual source of bugs:

  1. Format: does it match the shape for Chile? 9 digits: mobiles start with 9, Santiago landlines with 2, after the country code .
  2. Allocation: is the prefix actually in use? A number can be the right length and still belong to an unallocated range.
  3. Reachability: is there a live subscriber? Only a carrier lookup (HLR or equivalent) answers that, and it is the only check that catches disconnected numbers.

For form validation, check format only and be permissive: accept spaces, dashes, brackets, and a leading 0 then normalise. Rejecting a real customer because they typed their own number the way they normally write it is a far more expensive error than storing one badly formatted row.

Store in E.164 (+56981234567) and format for display at render time. Storing the display format is how a database ends up with the same person recorded four different ways.

Should I store phone numbers with the plus sign?
