A guide to writing numbers and currencies.

Numbers 0-9 should be written as words.

FOR EXAMPLE:

No fees for six months.

Numbers 10+ should be written using numbers.

FOR EXAMPLE:

Get credit for up to 30 days.


Use numerals instead of words for:

  • business days
  • age
  • school years
  • dates and business days
  • street addresses
  • tips articles
  • instructions
  • snappy copy
  • mobile apps where space is limited.

FOR EXAMPLE:

5 TIPS FOR PAYING OFF YOUR MORTGAGE FASTER.

6 WAYS TO SAVE MORE


Avoid starting a sentence or heading with a number unless it’s a rate, dollar amount, points or tips/reasons/steps, etc.

FOR EXAMPLE:

$3K CASHBACK WITH A WESTPAC HOME LOAN

$3,000 cashback.

Get $3k cashback….


Numerals 1,000+ use commas


Thousands, millions and billions can be expressed using k, m, b – and should always be used as such in headings, disclaimers and T&Cs.

FOR EXAMPLE:

5m customers…

$5b worth of shares…

Note: For points, it’s preferable to use ‘000s as it looks more impressive.


BSB numbers include a dash after the first three digits

FOR EXAMPLE:

732-118


Telephone numbers should include spaces.

FOR EXAMPLE:

6-digit: 132 032

10-digit: +61 2 9155 7700

Mobile: 0439 111 222

Note: Telephone numbers need to be hyperlinked and underlined for accessibility.


Number ranges use an en dash without spaces on either side.

FOR EXAMPLE:

8am–8pm

18–34 year olds

Years 7–12


Percentages should be %, not ‘percent’

FOR EXAMPLE:

Earn up to 3% p.a. interest

Get a fixed rate of 1.99% p.a.

Note: No decimal place if a whole number; two decimal places if any decimal applies.


Number rankings can either be:

  • ‘first’, ‘second’, etc.
  • #1, #2, #3
  • no.1, no.2

FOR EXAMPLE:

Westpac is Australia’s second biggest bank

Westpac is aiming to be Australia’s #1 mobile banking app.

Our no.1 business account.


No currency symbols on abbreviations of foreign currencies, e.g. AUD, USD, NZD, EUR, GB, etc.

FOR EXAMPLE:

Do: AUD100,000

Don't: AUD$100,000


Currencies are lower case when using the word.

FOR EXAMPLE:

euro, dollar, sterling, pound
