Android Question Regex for Australian phone number validation

First one: \+[0-9][0-9] *[0-9][0-9][0-9][0-9]-[0-9][0-9][0-9]-[0-9][0-9][0-9]
Second one: \+[0-9][0-9] *[0-9][0-9]-[0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]

I dont know how to put both in one regex but you can check both using and if

You can validate it here

I would try this (which is more or less the same as the above...
didn't test it though

To accept normal numbers only ie mobile service numbers starting with 04 and state area codes 02/03/07/08:


A looser version of the above that accepts any service or area codes (that start with 0):


Same again but also accepts service codes starting with 1 eg 1800 and 1300 numbers:

In human language:

\+61 will match the country code +61 (need to escape the + otherwise regex interprets it as a quantifier)

The space will match a space, ie there *must* be a space after the country code. You could put a quantifier after the space to make it optional: a + will match either 0 or 1 spaces, or a * will match 0 or 1 or multiple spaces.

(?: xxx | yyy | zzz) construct will match xxx or yyy or zzz etc

[01]\d{3} will match a 0 or 1 followed by 3 digits ie a 4 digit number starting with 0 or 1

[01]\d{3}-\d{3}-\d{3} will match:
a 4 digit number starting with 0 or 1, followed by
a hyphen, followed by
a 3 digit number, followed by
another hyphen, followed by
another 3 digit number

likewise, 0\d-\d{4}-\d{4} will match:
a 2 digit number starting with 0, followed by
a hyphen, followed by
a 4 digit number, followed by
another hyphen, followed by
another 4 digit number
