Caribbean · +297

Aruba phone number format

  • Country code +297
  • No trunk prefix

Reviewed by Sujan ThapaliyaLast updated

What does a Aruba phone number look like?

7 digits, no area code. Landlines are written +297 XXX XXXX and mobiles +297 XXX XXXX. In full international (E.164) format a Aruba mobile is written +2975931234: the country code +297, and no spaces or punctuation.
The anatomy of a Aruba phone number under ITU-T E.164: country calling code 297, then the national destination code, then the subscriber number, to a maximum of fifteen digits after the plus. Nationally a Aruba number is written +297 XXX 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 Aruba numbers in the right-hand form.

A quirk of Aruba numbering

Aruba is a common mix-up: despite being in the Caribbean it is *not* in the North American Numbering Plan. Dial +297, not +1.

Validation

How to validate a Aruba 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 Aruba? 7 digits, no area code, 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 (+2975931234) 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.

Frequently asked questions

What does a Aruba phone number look like?
7 digits, no area code. A landline is written +297 XXX XXXX and a mobile +297 XXX XXXX. In full international format that becomes +2975931234.
How do I write a Aruba number in international format?
Start with +297, then append the rest with no spaces or punctuation. +297 582 1234 becomes +2975821234.
How many digits is a Aruba phone number?
7 digits, no area code.
How do I tell a Aruba mobile from a landline?
You cannot tell from the number alone in Aruba: mobile and fixed lines share the same format, so a carrier lookup is the only reliable way.
Should I store phone numbers with the plus sign?
Yes. Store every number in E.164: leading +, country code, national number, no spaces or punctuation, up to 15 digits. It is the only format that is unambiguous internationally, and it is what makes deduplication work. Format for display, store canonical.
