 This guide is a working specification. We anticipate that it will be implemented and tested by FHIR system producers whose feedback will help improve its content. With this standard for trial use, we are looking for feedback on whether the following goals have been met: 
 - The guide provides guidance on essential resources for identifiers, code systems, value sets and naming systems in Switzerland, specifically in relation to the Swiss Electronic Patient Record ([EPR](https://www.patientendossier.ch/en)).
 - The guide defines extensions that are necessary for local use in Switzerland.
-- The guide covers the requirements for [eCH-0010 postal address (V7.0)](https://www.ech.ch/de/ech/ech-0010/7.0) and [eCH-0011 personal data (V8.1)](https://www.ech.ch/de/ech/ech-0011/8.1) (including [eCH-0007 municipality (V6.0)](https://www.ech.ch/de/ech/ech-0007/6.0) and [eCH-0021 additional personal data (V7.0)](https://www.ech.ch/de/ech/ech-0021/7.0)).
+- The guide covers the requirements for [eCH-0010 postal address (V7.0)](https://www.ech.ch/de/ech/ech-0010/7.0), [eCH-0046 contact (V5.0)](https://www.ech.ch/de/ech/ech-0046/5.0) and [eCH-0011 personal data (V8.1)](https://www.ech.ch/de/ech/ech-0011/8.1) (including [eCH-0007 municipality (V6.0)](https://www.ech.ch/de/ech/ech-0007/6.0) and [eCH-0021 additional personal data (V7.0)](https://www.ech.ch/de/ech/ech-0021/7.0)).
 - The guide incorporates Federal Statistics Office (BFS) variables for medical statistics. See [BFS](https://www.bfs.admin.ch/bfs/de/home/statistiken/kataloge-datenbanken/publikationen.assetdetail.7066232.html) (available in German, French and Italian).
 
 **Note**: This implementation guide is not (yet) a FHIR API specification, this will be a goal for the next iteration.
