Introduction

Korea has introduced a convenient new feature - the Mobile ID system that allows foreign residents to digitally verify their identity using their smartphones in addition to their physical Alien Registration Card (ARC).

First, download the Mobile ID app
After installation, follow these steps:
  1. Launch the app and select your preferred language
  1. Accept the terms and conditions
  1. Input your personal information exactly as it appears on your ARC:
      • Full name
      • Date of birth
      • Registration number
      • Phone number
  1. Complete identity verification
  1. Set up security measures (PIN or biometric authentication)
 

Step 1: Arrival at Immigration Office

Visit your jurisdictional immigration office in person as this service cannot be done online.
At Seoul Southern Immigration Office, head to the 2nd floor information desk to get your ticket number.

Step 2: Initial Processing

The entire process typically takes about 15 minutes from start to finish.

Important Notes

⚠️ While Mobile ID provides convenience, it's still recommended to carry your physical ARC with you at all times.
  • Mobile ID only works on the registered device
  • If you change your phone, you'll need to repeat the registration process
  • The service provides an additional verification method but doesn't replace your physical ARC
Having your ID available on your phone can be particularly useful in situations where digital verification is accepted, offering a convenient backup to your physical card.
 

Conclusion

Korea continues to demonstrate its commitment to digital transformation, with Mobile ID being just one example of the country's push towards a more connected and efficient future. The government's dedication to digitizing services not only benefits Korean citizens but also makes life increasingly convenient for foreign residents.
While the pace of change might sometimes feel slow for foreigners eagerly awaiting digital solutions, it's encouraging to see steady progress in making administrative processes more accessible. From online banking to digital health certificates, and now Mobile ID, Korea is gradually breaking down bureaucratic barriers and creating a more user-friendly environment for its international community.
These incremental improvements show promise for future developments, suggesting that Korea will continue to evolve its digital infrastructure to better serve both its local and foreign populations.
