How to Find Your Strata Plan Number in NSW

Every strata building in NSW has a unique plan number — usually written as "SP" followed by a number (e.g. SP 12345). You need it to look up your building's financial health, check for disputes, or lodge paperwork with NSW Fair Trading. Here's how to find yours.

What Is a Strata Plan Number?

A strata plan number is the unique identifier assigned to every strata scheme registered in NSW. It's issued by NSW Land Registry Services when the strata plan is registered and stays the same for the life of the scheme.

The format is simple: "SP" followed by a number. Older buildings might have a 4 or 5-digit number (e.g. SP 1234), while newer developments can have 6 digits (e.g. SP 107823).

Think of it like an ABN for a strata building — it's how government agencies, strata managers, and legal systems identify the scheme.

Why You Need Your Strata Plan Number

You'll need your strata plan number to:

  • Research a building before buying — look up the building's levy history, financial health, and any NCAT disputes
  • Lodge an application with NSW Fair Trading — mediation applications require the plan number
  • Order a strata records inspection — strata search companies need the plan number to locate the correct scheme
  • Check who manages your building — the plan number links to the current strata manager
  • File with NCAT — the NSW Civil and Administrative Tribunal requires the strata plan number for all strata disputes

4 Ways to Find Your Strata Plan Number

2. Check Your Levy Notice

If you already own a unit in a strata scheme, the easiest place to find your plan number is on your quarterly levy notice. It's usually printed near the top of the document, alongside the scheme name and your lot number.

Look for text like: "Strata Plan SP 12345 — Lot 7" or "SP12345". Some strata managers also include it in the subject line of levy emails.

3. Look at Your Contract of Sale

The contract of sale for any strata property includes the strata plan number in the property description. It's typically in the first few pages, written as part of the legal description:

"Lot 7 in Strata Plan SP 12345 at 42 Example Street, Sydney NSW 2000"

If you're buying, your conveyancer or solicitor will have this. If you've already purchased, check your settlement documents.

4. Search NSW Land Registry Services

NSW Land Registry Services (LRS) maintains the official register of all strata plans. You can search their portal at nswlrs.com.au, though you may need to pay a small fee for detailed records.

This is the most authoritative source, but it's slower and less convenient than searching online. It's mainly useful when you need the official strata plan document itself — the registered plan showing lot boundaries and common property.

What You Can Do With Your Strata Plan Number

Once you have your plan number, you can look up a wealth of information about the building:

  • Financial health — check the admin fund and capital works fund balances, quarterly levy amounts, and how they compare to similar buildings in NSW
  • Strata manager — see who currently manages the building, their licence number, and how many other buildings they manage
  • Disputes — check whether the building has had any NCAT tribunal cases
  • Building details — number of lots, year registered, address, and location
  • Sales history — recent sale prices for units in the building

Common Questions

Is a strata plan number the same as a lot number?

No. The strata plan number (e.g. SP 12345) identifies the entire building or scheme. The lot number (e.g. Lot 7) identifies your individual unit within that scheme. You need both to uniquely identify a specific apartment.

What if my building has multiple strata plans?

Large developments sometimes have more than one strata plan — for example, a mixed-use complex might have one plan for residential lots and another for commercial lots. Each plan operates as a separate owners corporation with its own levies and funds. Search by your specific address to find the correct plan.

Can I find the strata plan number for a building I don't own?

Yes. Strata plan numbers are public information. You can search for any building's plan number on StrataChecks — no account or ownership required. This is especially useful for buyers researching a building before purchase.

What does the number after SP mean?

The number is simply a sequential identifier assigned when the strata plan was registered. Lower numbers generally indicate older buildings — SP 1000 was registered decades ago, while SP 100000+ are recent developments. The number itself doesn't encode any information about location or building type.

The Bottom Line

Finding your strata plan number takes seconds if you search by address. Once you have it, you can research the building's financial health, check for disputes, identify the strata manager, and make more informed decisions — whether you're buying, selling, or already living in the building.
