# What is an org-id identifier?

**org-id**: An org-id is a standard way of identifying an organisation in open data: a list code naming the register, then the organisation's number on it, for example GB-CHC-200051 for a registered charity or GB-COH-09506232 for a company. 360Giving uses org-ids for every funder and recipient.

An org-id is a standard organisation identifier used in open data. It joins a list code, which names the register an organisation appears on, to that organisation's number on the register. The org-id.guide register of lists, maintained by Open Data Services Co-operative for partners including 360Giving, gives the example GB-COH-09506232, where GB-COH is the list code for Companies House and 09506232 is the company number. A charity registered in England and Wales is GB-CHC- plus its charity number, a Scottish charity GB-SC- plus its SC number, and a Northern Ireland charity GB-NIC- plus its NIC number.

**Why it matters when applying.** Every grant published in the [360Giving](https://opengrant.co.uk/glossary/360giving) Data Standard must carry a funding organisation identifier and a recipient organisation identifier, and those are org-ids. That is what lets [GrantNav](https://opengrant.co.uk/glossary/grantnav) gather every grant a charity has received onto one recipient page, and every grant a funder has made onto one funder page, however the names were spelt. If your organisation's name changed, the org-id still matches.

**How to use it.** GrantNav funder pages sit at an address ending in the org-id, so the Esmée Fairbairn Foundation is at /org/GB-CHC-200051. OpenGrant's [peers lookup](https://opengrant.co.uk/peers) accepts a [charity number](https://opengrant.co.uk/glossary/charity-number) or an org identifier and uses the same scheme to match organisations to published grants. [How to use 360Giving data to find funders](https://opengrant.co.uk/blog/how-to-use-360giving-data-to-find-funders) works through the steps.

**Example.** A fictional community interest company has no charity number, so in 360Giving data it appears under its Companies House number as GB-COH- followed by eight digits. Searching GrantNav by that identifier shows every publishing funder that has given to it.
