Erf number lookup: how to find an erf number by address in Johannesburg

Every formal property check in South Africa starts with the same small piece of information: the erf number. Banks, conveyancers, town planners and the municipality all identify a property by its erf number and township, not by its street address. If you only have the address, an erf number lookup is the first thing to do.

What an erf number actually is

An erf (plural: erven) is a surveyed piece of land in a proclaimed township. Its legal description has two parts: a number and the township it belongs to — for example "Erf 1234, Bryanston". The number alone is not unique. There is an Erf 1234 in dozens of townships, which is why an erf number search always needs the township, or a street address that pins the township down.

You will also see the word "stand" used for the same thing. A stand number search and an erf number search are, in everyday use, the same exercise. If the terminology is new, erf, stand and portion are decoded here.

Find erf number details on documents you already have

Before searching, check whether you already have it:

• The municipal rates account. The property description on the account normally gives the erf (stand) number and township.
• The title deed. The property clause describes the land by erf number, township, registration division and extent.
• The offer to purchase or sale agreement. A properly drafted agreement describes the property by its erf, not only its address.
• Approved building plans and the survey diagram. Both carry the erf number in the title block.
• The agent's mandate or listing pack. Agents usually hold the erf number even when the advert only shows the street address.

If you are a buyer and have none of these, you are in the common situation: an address and nothing else.

How to find an erf number by address

The address and the erf number are two different systems. Street addresses are allocated for postal and navigation purposes; erf numbers come from the survey of the township. An erf lookup by address works by placing the address on a map and reading off which surveyed parcel it falls inside.

On checkproperty.co.za the steps are:

1. Type the street address into the search box. Suggestions appear as you type.
2. Pick the matching result. The property opens with its boundary drawn on the map.
3. Read the erf number and township from the heading, together with the suburb and region.

An erf search also works the other way around. If you already know the number, typing the erf number and township takes you straight to the property — useful when a document gives you "Erf 567 Ferndale" and you want to see where that actually is.

When the address and the erf do not match neatly

A few situations cause confusion, and it helps to recognise them.

Corner stands. A corner property may be known by an address on either street. The erf is the same; only the address differs.

Consolidated or subdivided land. If two erven were consolidated, the old numbers fall away and a new one is issued. If an erf was subdivided, you get portions — "Portion 1 of Erf 1234" — each a separate property. An old document may quote a number that no longer exists in that form.

Sectional title schemes. A flat or townhouse in a sectional scheme is a unit in a scheme that stands on an erf. The erf number describes the land the whole complex sits on, not your individual unit. The difference is explained in freehold versus sectional title.

Estates. Some estates use internal stand numbers for marketing that are not the registered erf numbers. Always confirm against the map boundary.

Why the erf number matters

Once you have the erf number, every other check becomes possible:

• Zoning is recorded per erf.
• The survey diagram is filed under the erf.
• The municipal valuation roll lists the property by erf.
• Sales history and title details are recorded against the erf, not the address.

An address tells a courier where to go. An erf number tells you what is legally being bought and sold.

Quick checks to make after the lookup

When the property opens, take thirty seconds to confirm you have the right one:

• Does the boundary on the map match the fences and walls you saw on site?
• Does the erf size agree with what the advert claims?
• Is the suburb name the one you expected? Marketing suburbs and registered townships often differ.

If any of these look wrong, you may have picked a neighbouring erf, or the listing may be describing more (or less) land than is actually registered.

Frequently asked questions

Is an erf number the same as a stand number? In practice, yes. "Stand" is the everyday word; "erf" is the term used in the deeds registry and on survey diagrams.

Can two properties have the same erf number? Not within the same township. Across different townships the same number is reused constantly.

Does a farm portion have an erf number? No. Land outside a proclaimed township is described as a farm portion, for example "Portion 12 of the Farm Zevenfontein". checkproperty.co.za covers erven in Johannesburg townships.

The bottom line

An erf number search takes a minute and unlocks everything else. Start with the address, confirm the boundary on the map, and write the erf number and township down — you will quote it to everyone involved in the transaction.
