Only with the MWST\/TVA\/IVA suffix does it signify that the company is registered for VAT.<\/p>\n<h2 id=\"uid\">UID or VAT number: are they the same?<\/h2>\n<p>Yes. Since <strong>1 January 2014<\/strong>, the UID (Unternehmens-Identifikationsnummer \/ business identification number) replaced the old six-digit Swiss VAT number. Every registered business now uses its UID, and its VAT number is simply that same UID followed by the VAT suffix.<\/p>\n<p>So a company has one identifier used across the administration (commercial register, customs, statistics), and when it is VAT-registered, that identifier \u2014 with the MWST\/TVA\/IVA suffix \u2014 is also its VAT number.

An invoice from a supplier whose number cannot be validated can have its input-tax deduction refused.<\/p>\n<h2 id=\"get\">How to get a Swiss VAT number<\/h2>\n<p>You do not apply for a VAT number as such: you <strong>register for VAT<\/strong>, and the number is issued as part of that process. Once the FTA validates your registration, it activates the VAT suffix on your UID.<\/p>\n<p>The full registration procedure \u2014 threshold, documents, timeline \u2014 is covered in our <a href=\"https:\/\/www.rister.ch\/en\/post\/vat-in-switzerland-complete-guide\/\">complete guide to VAT in Switzerland<\/a>.

It is the prefix &#8220;CHE&#8221;, nine digits (the last a MOD11 check digit), and a VAT suffix \u2014 MWST in German, TVA in French, IVA in Italian. Without the suffix, the number is just the business identification number (UID).<\/p>\n<\/p><\/div>\n<div class=\"question\">\n<h3>Is the UID the same as the VAT number in Switzerland?<\/h3>\n<p>Yes. Since 1 January 2014 the UID replaced the old six-digit VAT number. A VAT-registered company&#8217;s number is its UID followed by the MWST\/TVA\/IVA suffix. There is no separate VAT number.<\/p>\n<\/p><\/div>\n<div class=\"question\">\n<h3>How do I check a Swiss VAT number?<\/h3>\n<p>Use the official UID Register (uid.admin.ch), free of charge. Search by company name or enter the UID to confirm the number exists and is registered for VAT. This is worth doing before deducting input tax on a supplier&#8217;s invoice.<\/p>\n<\/p><\/div>\n<div class=\"question\">\n<h3>How do I get a Swiss VAT number as a foreign company?<\/h3>\n<p>Register for Swiss VAT with the FTA; the number is issued as part of registration. A foreign company without a permanent establishment must appoint a fiscal representative domiciled in Switzerland to register and to use the number.<\/p>\n<\/p><\/div>\n<\/section>\n<section id=\"sources\">\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.uid.admin.ch\/\" target=\"_blank\" rel=\"noopener\">Federal Statistical Office \u2014 UID Register (uid.admin.ch)<\/a><\/li>\n<li><a href=\"https:\/\/www.estv.admin.ch\/en\/register-for-vat\" target=\"_blank\" rel=\"noopener\">FTA \u2014 Register for Value Added Tax<\/a><\/li>\n<li>Swiss VAT Act (MWSTG \/ LTVA) \u2014 RS 641.20 ; UID Act (LIDE) \u2014 RS 431.03<\/li>\n<\/ul>\n<\/section>\n<div class=\"conclusion-box\">\n<h2>Conclusion<\/h2>\n<p>The Swiss VAT number is straightforward once two things are clear: the format is CHE-123.456.789 MWST, and since 2014 it is simply your UID with a VAT suffix.
