There is no single universal “KiwiSaver number”. When a form or a provider asks for your KiwiSaver account number, it usually means one of two things: your provider’s member or account number, or your IRD number, which links your KiwiSaver record at Inland Revenue. Here’s what each is and where to find it.
If you’re after your balance rather than a number, see how to check your KiwiSaver balance.
Your IRD Number — The Master KiwiSaver Reference
The primary number linking you to KiwiSaver is your IRD number, a unique 9-digit number issued to you by Inland Revenue (if yours shows 8 digits, add a 0 at the start when entering it).
Your IRD number is how IRD identifies your KiwiSaver membership, processes contributions from your employer, and pays the government contribution. Your provider also uses it to verify your identity.
How to find your IRD number:
- Check any IRD correspondence (letters, tax summaries)
- Log in to myIR (myir.ird.govt.nz) — your IRD number appears in your profile
- Check your payslip — your employer may list it
- Check a previous tax return (IR3 or income summary)
- If you’ve lost it: call IRD on 0800 227 774 with your details
Your Provider Member Number
In addition to your IRD number, your KiwiSaver provider assigns you a member number or account number specific to their system. This is used when contacting your provider directly.
How to find it:
- Log in to your provider’s online portal or app — it appears in your account details
- Check your annual KiwiSaver statement (posted or emailed to you each year)
- Call your provider’s customer service line — they can look up your account with your name, date of birth, and IRD number
Which Provider Are You With?
If you’ve lost track of which provider holds your KiwiSaver:
- Log in to myIR at myir.ird.govt.nz
- Go to your KiwiSaver account panel
- Your current provider is shown there
This is the fastest way to locate your account if you’re unsure.
How to Find KiwiSaver If You Were Auto-Enrolled
If you were automatically enrolled when you started a job and never chose a scheme, you may have been allocated to a default provider (or your employer’s chosen scheme). myIR shows which provider holds your account.
See KiwiSaver default fund explained for more.
KiwiSaver and Your IRD Number — When You Need It
You’ll typically be asked for your IRD number when:
- Enrolling in KiwiSaver with a provider
- Completing a KiwiSaver application form (a first home withdrawal, a savings suspension or a rate change)
- Switching providers: both old and new provider require it
- Making a voluntary contribution via bank transfer (some providers use it as the payment reference)
What If You Have Multiple KiwiSaver Accounts?
You can only be an active member of one KiwiSaver scheme at a time. However, historically some members ended up with accounts in more than one fund (from changing jobs without properly managing the switch). If you suspect you have duplicate accounts:
- Check myIR — it will list your current registered provider
- Contact any other providers you remember joining
- Arrange a transfer to consolidate into a single account
