Why identifiers matter
Identifiers are an important part of any dataset. They let a computer uniquely identify and refer to specific grants, organisations, transactions and so-on.
Whilst a human being may be good at recognising that “Big Lottery Fund”, “BLF”, and “big-lottery-fund” all refer to the same organisation, computers cannot make this connection unless a unique identifier is provided.
360Giving asks you to give identifiers to any of the following elements that you include in your data:
- Grant Identifier
- Organisation Identifier;
- and other unique elements in your data.
These go in an
Identifier column alongside accessible text descriptions of the grant, the name of an organisation, or the title of a classification.
You may already have identifiers in your own data. For example, a number for each application or grant. You can use these existing internal identifiers as part of your published data.
However, because there might be an overlap between the internal identifiers you use, and the internal identifiers another funder uses, you need to add a prefix to avoid this possible clash.
If Indigo Trust have a grant called ‘Grant27’, and Nominet Trust also have a grant called ‘Grant27’ the two will get confused when combining the two datasets. But if, when publishing, each one adds a prefix, then we end up with two unique identifiers: ‘360G-indigotrust-Grant27’ and ‘360G-Nominet-Grant27’
For grants, and other identifiers particular to your organisation, you use can use a 360G prefix.
For organisation identifiers, we strongly encourage you to use an officially recognised identifier for the organisation, following the Organisation Identifier guidance below.
Get your prefix¶
To register a prefix for your organisation see the publisher guidance.
All registered prefixes should start with 360G unless you have been advised otherwise by the support team.
To create your grant identifiers:
- Make sure you have asked for a 360Giving prefix.
- Look for an existing internal identifier given to your grants (for example, a sequential number assigned to each grant at the point of application). The important thing is that the identifier should be unique inside your organisation, so adding the prefix will make it unique across the whole world.
- Add your 360Giving prefix in front of your identifier.
If your prefix is
360G-xyztrust and you have a grant identified internally as
123, you would combine these to give
We recommend using a hyphen (-) for the separator to use between your prefix and the internal identifier. Avoid using slashes (\ and /) as these can cause problems with some applications.
If your internal identifiers include spaces or special characters, we recommend replacing these with underscore (_):
There are many different kinds of organisations that give, receive or benefit from grants, such as:
- Registered companies
- Registered charities
- Voluntary and community organisations
- Overseas organisations
- Public bodies
- Schools, universities and other educational establishments
Most organisations (with the exception of unregistered voluntary and community groups) have some sort of official registration number that can be used as a unique identifier and used to look up their details from an official registers or public list.
There are two parts to an organisation identifier:
- A list code: a prefix that describes the list the identifier is taken from.
- An identifier taken from that list.
In 360Giving data we ask publishers to use a list code prefix taken from the org-id list locator. This provides an open, maintained list of codes for many different lists around with world, giving a way to identify almost any organisation.
A charity registered in England and Wales with the Charity Commission of England and Wales, with the charity number ‘1070468’ will use a list code prefix of
This gives an unique organisation identifier of
UK company numbers are a unique combination of eight digits, which in some cases include letters as well as numbers. The majority of company numbers for companies registered in England and Wales start with a leading zero.
Publishers should be aware of the problems that missing leading zeros in UK company numbers present when creating identifiers. Learn more about how to avoid this pitfall.
Choose the best identifier¶
Some organisations have more than one identifier: they might be a charity and a company (charitable companies), or a charity and an educational establishment.
If you have more than one type of identifier for an organisation recorded in your system, it will be necessary to pick which one to use when creating an Organisation identifier.
org-id.guide ranks identifier lists by relevance and quality to help you pick the best identifier, based on what information you hold.
Relevance and quality defined:
- Relevance: are you likely to find the organisation you are looking for in this list?
- Quality: are the identifiers in this list stable and linked to open, accessible contextual data, and can they be easily mapped to other identifiers.
Commonly used identifier lists¶
The following identifier lists are often used in 360Giving publication.
- UK Company Number - GB-COH
- Charity Numbers - GB-CHC, GB-SC, GB-NIC
- Education establishments - GB-EDU and GB-UKPRN
- Local authorities - GB-LAE (England), GB-LAS (Scotland), GB-PLA (Wales)
- Mutual societies - GB-MPR
- HMRC-recognised charities - GB-REV
If you have a registered number from some other scheme, including overseas registrars, check the org-id List Locator for a list code prefix to use. If the list code prefix you need is not listed, contact the support team.
If you do not have any external registration numbers for the organisation, use your 360Giving prefix and any internal identifier you have for this organisation. For guidance about how to create unique internal identifiers, contact the support team.
Additional 360Giving fields for charity and company number
Because ‘Company Number’ and ‘Charity Number’ are so important for analysing grantmaking in the UK, the 360Giving Standard includes additional fields these on their own (without the prefixes), to help users of the data.
If you have these details, you should fill them in, in addition to providing the unique organisation identifier using the method above.
