Mobile Number Formatting for SMS

When sending SMS messages, the safest option is to send numbers in internationalised E.164 format (often called MSISDN format). For example, +642100001 and +61400010001.

Your account can be pre-configured to accept New Zealand and Australian formatting. This means you can submit NZ and AU numbers as a mixture of:
+6421000001 and +61400010001
006421000001 and 0061400010001
6421000001 and 61400010001
021000001 and 0400010001
21000001 and 400010001

Note:

1. International numbers will still require a leading + or 00, e.g. +447955554444.
2. The service is able to accept and strip any unnecessary characters, such as spaces, dashes and brackets.
3. If you prefer globalised E164 format without a leading +, contact your account manager.
4. We do not support ENUM format (1.0.0.0.0.1.2.4.6.e164.arpa) currently.
