There are 1109 exchange groups of the Community Exchange System (CES) in 101 countries. Join an exchange in your area or, if there is not one, consider starting one.

All exchanges are linked through the Community Exchange Network so inter-exchange trading is possible.

Join an existing CES exchange group

If you would like to join an existing CES exchange group, select your country below. From the list of exchange groups that appears, click on the name of the one you would like to join. Fill in the joining form and within 24 hours you will be sent an account number and password, which you can use to log in above.


For your registration to be accepted your contact details are required. If you are concerned about your details appearing on the internet, it is possible to hide them. Your details are not open to the public and are only seen by other CES users. Ensure that you fill in your email address for a rapid response. You may register as a company, a family, an individual or an organisation. Your details will not be provided to any third parties.

Please also provide details of what goods and/or services you will be able to offer. Exchange groups are relatively small, closed communities so make offerings that are meaningful in that context  (click here for more information about offerings).

If you require further information please write to

NB: Please do not register just to have a look. The demonstration site contains most of the features that appear on the real site. We are seeking active participants who wish to trade with others of their communities.
