Fix a field format error
What OneForce Care expects for phone, ABN, NDIS numbers and other formatted fields, so a rejected value is quick to fix.
Last updated · 3 July 2026
A handful of fields run the same format check wherever they appear: a worker’s phone number, a participant’s NDIS number, your organisation’s ABN. Get the shape wrong and OneForce Care blocks the save with a toast naming the exact problem. This page lists what each field actually accepts, so you can fix it on the first try instead of guessing.
Note
These checks fire when you select a save button (Send invite, Create participant, Save, and so on), not as you type. The toast appears in the corner of the screen and the field itself keeps whatever you typed, so you can correct it and try again without losing your other entries.
Phone numbers
Spaces, dashes and brackets are all fine; OneForce Care strips them before checking the shape. Once stripped, the number must match one of:
| Kind | Accepted shape |
|---|---|
| Mobile | 04XX XXX XXX (or +614XX XXX XXX) |
| Landline | 0X XXXX XXXX where X is 2 (NSW/ACT), 3 (VIC/TAS), 7 (QLD) or 8 (SA/WA/NT) |
| Freecall | 1300 XXX XXX or 1800 XXX XXX |
| 13 number | 13 XXXX |
A leading +61 (or 61) is accepted in place of the leading 0 for mobiles and landlines. Anything else, including a number with too few or too many digits, or a + that isn’t at the very start, is rejected.
Watch out
New intake enquiries are looser: the New intake form only checks that a phone number has 8 to 15 digits, not the shapes above. It’s meant to accept a number as it’s first given to you and get tightened up later. The full check above applies everywhere else a phone number is saved, including once the enquiry is converted to a participant.
Email addresses
A standard name@domain.tld shape: no spaces, a real domain with at least one dot, and the part after the last dot at least two characters (so name@example.c is rejected, name@example.com is not). The domain’s last two labels can’t be identical (catches obvious typos like name@example.example).
NDIS numbers
There are two different NDIS number fields, and they don’t use the same rule:
- A participant’s own NDIS number, and the NDIS plan number on their NDIS Plans tab, and your organisation’s own NDIS registration number under Account ›Organisation , all take 8 to 11 digits, no letters or spaces.
- The NDIS number on a new intake enquiry takes exactly 9 digits, no more and no less. This is deliberately stricter at the intake stage; once the enquiry is converted to a participant, the participant record follows the 8-to-11-digit rule like everywhere else.
ABN and ACN
ABN (Australian Business Number) must be 11 digits (spaces are fine, for example 51 824 753 556) and pass the ATO’s official checksum, so a made-up or mistyped 11-digit number is still rejected. If you’re not sure your ABN is right, search it at abr.business.gov.au.
ACN (Australian Company Number) must be exactly 9 digits; spaces are optional and no checksum is applied.
NDIS Worker Screening ID
7 or more digits, required for anyone invited as a Support worker. No upper limit and no letters.
Working With Children Check (WWCC) number
Optional, but if you enter one it has to match your state’s format:
| State | Example format |
|---|---|
| NSW | WWC1234567E (or V at the end) |
| QLD | 12345/1 (Blue Card or Exemption) |
| SA | SRN 1234-5678 |
| VIC | 1234567A (7 digits then a letter) |
| ACT, NT, TAS, WA and teacher checks | 4 to 8 digits, no letters |
Centrelink CRN
9 digits followed by one letter, for example 123 456 789A. Spaces are optional.
Medicare number
10 or 11 digits, spaces optional.
Website
A domain with a dot and a top-level domain, for example example.com.au. The http:// or https:// prefix is optional; a port or path after the domain is fine too.
Postcode and address
A postcode has to be a real, issued Australian postcode: 0200–0299 (ACT), 0800–0999 (NT), or 1000–9999. If you type a street address instead of choosing a match from the lookup dropdown, save it with Enter address manually so the state (and postcode) gets set explicitly, otherwise the save is blocked until it is.
The exact toasts
“Enter a valid email address.”
Means: The email address is not a valid format.
Fix: Use a full address like name@example.com, with no spaces and a real domain.
“Enter a valid Australian phone number (e.g. 04XX XXX XXX or 0X XXXX XXXX).”
Means: The number is not a recognised Australian format.
Fix: Enter a mobile (04XX XXX XXX), a landline (0X XXXX XXXX), or a 1300/1800 number. Spaces, dashes and brackets are fine.
“NDIS number must be 8 to 11 digits.”
Means: The participant NDIS number is the wrong length.
Fix: Enter the NDIS number from the participant's plan. It must be 8 to 11 digits, with no letters.
“NDIS Worker Screening ID must be 7 or more digits.”
Means: A support worker needs a valid NDIS Worker Screening clearance number, and the one entered is too short.
Fix: Enter the worker screening ID (7 or more digits) from their clearance.
“Enter a valid ABN.”
Means: The ABN failed the official 11-digit checksum, so it is not a real ABN.
Fix: Check the 11 digits against the business record (search abr.business.gov.au).
“ACN must be 9 digits.”
Means: The Australian Company Number is the wrong length.
Fix: Enter the 9-digit ACN (spaces are optional).
“Enter a valid WWCC or equivalent number for your state (e.g. NSW: WWC1234567E, QLD: 12345/1, SA: SRN 1234-5678, VIC: 1234567A, or digits for other states).”
Means: The Working With Children Check number does not match your state format.
Fix: Enter the check number exactly as it appears on the card, using your state format (the message lists examples).
“CRN must be 9 digits followed by a letter (e.g. 123 456 789A).”
Means: The Centrelink Customer Reference Number is in the wrong shape.
Fix: Enter 9 digits then a trailing letter, for example 123 456 789A.
“Medicare number must be 10 or 11 digits.”
Means: The Medicare number is the wrong length.
Fix: Enter the 10 or 11 digit Medicare number.
“Enter a valid website URL.”
Means: The website address is not a valid URL.
Fix: Enter a domain like example.com.au (the http prefix is optional).
“Enter a valid Australian postcode.”
Means: The postcode is not within a valid Australian range.
Fix: Enter a valid 4-digit Australian postcode.
“Select an address from the dropdown, or use "Enter address manually" to set the state.”
Means: You typed an address line but no state has been set, which the record needs.
Fix: Pick a suggestion from the address dropdown, or click "Enter address manually" and choose the state.
Tip
Left a required field blank instead of getting the format wrong? You’ll see a message naming the exact field, for example “Plan number is required.” (
what this means). Seeing a workspace error rather than a field one? That’s covered in Why can’t I see or edit this?, along with what a missing workspace looks like .
