The Union ID app is a digital ID wallet used by union members to store the digital ID cards issued by their trade union, labor union or association. You must receive a digital ID card invitation email from your union in order to use this app. If your union is not registered with us, please have them contact us and we’ll set up an account for them. Unions are making their ID cards more useful and convenient for their members by offering them digitally. The Union ID app stores your digital union ID card on your mobile device. It offers a simple way to prove your affiliation. You can also opt-in to receive messages, updates and information from your union. Didn’t get your invite? Ask your union representative to issue you a digital union ID card through ID123 (https://www.id123.io).
