Dialing sequence, step by step

  1. 1

    Start with + on a mobile, or 0011 when the Australia network requires an all-digit access prefix.

  2. 2

    Add 65, the country calling code for Singapore.

  3. 3

    Add the destination national significant number. There is no domestic trunk prefix to remove from ordinary eight-digit numbers.

Singapore ordinary mobile and fixed-line numbers have eight digits and no trunk 0. Australia commonly uses 0011 when + is not available.

Mobile and landline examples

X means a subscriber digit placeholder, so these patterns explain the transformation without publishing a private callable number. Save the + format; use the access-prefix format only for a call that starts in Australia.

How the international format is built

Portable contact format

+ 65 + national significant number

The + represents international access. It is display notation, not one of the E.164 digits.

Digits-only call from Australia

0011 + 65 + national significant number

The first part routes out of the origin network and must not be stored as part of the destination.

E.164 limits the full international number to 15 digits and excludes international and national prefixes. See the E.164 and international-format guide for the reusable structure and regional exceptions.

Common mistakes for this route

  • Adding a leading 0 to the eight-digit Singapore destination number.
  • Saving Australia's 0011 access prefix as though it were part of the Singapore number.
