Difference Between a Building Society & a Bank

If you haven’t spent a lot of time in the UK, you probably haven’t heard the term building society before. Fortunately, there’s a direct comparison in most countries, credit unions.

Building societies and credit unions are very similar. In fact, the only real difference is found in the services that they offer their members.

While credit unions typically reflect more traditional banking activities for both individuals and businesses, building societies are almost exclusively focused on helping members buy homes through mortgages that they offer.

That said, in terms of personal banking, both building societies and credit unions typically offer savings accounts, current (or checking) accounts, credit cards, and other personal loans.

Of course, there are a few other differences between building societies and traditional banks as well, including the numbers that get issued during account opening. With this in mind, let’s take a closer look at what is a bank or building society number below.

Building Society Numbers

When you open an account with a traditional bank, you will typically receive an account number. Depending on where you open in the world, the length of this number can vary.

For example, standard UK bank accounts have eight characters plus a six-character sort code, while IBANs vary and can go up to 34 characters.

When opening an account at a building society, you will also receive a standard account number, which will be used anytime you need to receive funds into your account.

However, there is another number that often gets confused when dealing with building societies, which is a building society roll number.

What is a Building Society Roll Number?

First of all, a building society roll number is not a number at all, in fact, it’s a combination of letters and numbers that is better described as a reference code.

The purpose of the building society roll number is to identify the individual’s account, typically a savings account.

Today, a building society roll number is not always required when sending transfers to a building society account. But, when it is required, the roll number will be added to the “reference” portion of the transfer details.
