Identifier Qualification (Company identification number (Switzerland), Data source:CH.UIDR) ACCURACY	CH (Switzerland)	This rule compares the Swiss company identification number in the business partner record with the identifier held as reference in the Swiss UID register. A value that does not match the reference is flagged.	INFO	RELEASED(2025-06-25)
Identifier checkdigit invalid (Company identification number (Switzerland)) ACCURACY	CH (Switzerland)	The last digit of the Swiss company identification number is a MOD11 checksum digit calculated with the weighting pattern 5, 4, 3, 2, 7, 6, 5, 4. This rule recomputes that digit and flags a value that does not match. It accepts any correctly formatted Swiss UID, if the format itself is invalid, which the separate rule on the format of the Swiss company identification number covers, this rule fails immediately.	ERROR	RELEASED(2020-01-01)
Identifier format inaccurate (Company identification number (Switzerland)) REPRESENTATIONAL_CONSISTENCY	CH (Switzerland)	This rule checks whether the Swiss company identification number is written exactly in its reference format, any deviation, such as a whitespace where none is specified, results in a violation. For better readability a hyphen is placed between the prefix and the numerical part of the UID number, and the numerical part is likewise split into three blocks of three digits separated by dots. A UID number therefore has the shape CHE-999.999.999 followed by HR, RC, HR/MWST, RC/TVA or RC/IVA. Which extension applies depends on the part of Switzerland concerned: MWST in the German-speaking part, TVA in the French-speaking part and IVA in the Italian-speaking part.	INFO	IDEA(2020-01-01)
Identifier format invalid (Company identification number (Switzerland)) REPRESENTATIONAL_CONSISTENCY	CH (Switzerland)	The Swiss company identification number consists of the prefix CHE followed by nine digits and, optionally, HR or RC, so that a UID number has the shape CHE-999.999.999 HR. Where the identification number is also used as a VAT number, the suffix may in addition carry the abbreviations MWST, TVA or IVA in any combination with HR and RC, for example HR/MWST, RC/TVA or RC/IVA. This rule checks that the prefix and exactly nine digits are present, disregarding any whitespaces, hyphens or dots in the value. A value with too few, too many or misplaced digits or letters, or one that lacks the prefix, violates the rule.	ERROR	RELEASED(2020-12-28)
