As of Sept 21, 2026, a foreign resident opening a Korean phone line with an Alien Registration Card (외국인등록증, oegugin deungnokjeung, “ARC”) is not on the ministry’s face-scan list. Since July 6, carriers must match a live face to the ID photo for new lines and carrier switches, but the ministry names only the resident registration card and the driver’s license.
I am a Korean who builds internal systems at a financial company, so I read this rule as a systems question first: a face match is only as trustworthy as the reference it is compared with. Everything here comes from ministry notices and dated news reports, not from a counter visit. I date each claim because Korean government pages stay online in old versions, and the December 2025 pilot text and the June 30, 2026 rules do not say quite the same thing.
Who Gets Face-Scanned at a Korean Phone Shop Today?
The ministry drew its line by ID document, not nationality, so the table sorts by what you put on the counter.
| ID shown at the counter | Face scan today? | Dated source |
|---|---|---|
| Resident registration card (주민등록증, jumin deungnokjeung) | Yes, since Jul 6, 2026 | ID types: Ministry of Science and ICT (MSIT) notice, Dec 19, 2025; start date: rollout announcement, Jun 30, 2026 (both korea.kr) |
| Driver’s license (운전면허증, unjeon myeonheojeung) | Yes, since Jul 6, 2026 | Same sources |
| Interior Ministry mobile ID app (모바일 신분증, mobail sinbunjeung) | Accepted instead of the scan | Maeil Business Newspaper Q&A on the MSIT announcement, Jun 30, 2026 (Daum News) |
| ARC | Not on the list yet | Same Dec 19 notice; ID Tech, Jun 23, 2026 |
| Passport | No, no confirmed start date | Asia Business Daily, Jul 7, 2026 |
The ARC row rests on the ministry’s own wording. Its Dec 19, 2025 policy notice on korea.kr says the face check applies to activations made with a resident registration card or a driver’s license, and that in “the second half of next year”, meaning 2026, it would extend to other IDs, including the veterans’ card, the disability registration card and the ARC. That notice describes the pilot, so I read it against later reporting: ID Tech (Jun 23) and Asia Business Daily (Jul 7) both describe foreigners as outside the rollout. As of Sept 21, 2026, I found no announcement in Korean or English that the ARC extension has started. That describes my search, not tomorrow’s counter.
Two cautions. A foreign resident who opens a line with a Korean driver’s license is presenting a listed ID on the notice’s wording, and I found no source on how counters treat that case, so I would not assume either way. And at least one English expat guide says foreigners get face-matched and chip-scanned. I found no primary source, and it conflicts with the ministry’s list.
What Actually Started on July 6, 2026?
Face verification (안면인증, anmyeon injeung, “face authentication”) became mandatory on Monday, July 6, 2026, at SK Telecom, KT, LG U+ and the budget carriers (알뜰폰, alddeulpon, “thrifty phone”, the MVNOs), in stores and online. It covers new lines and carrier switches (number portability). Reports differ on device changes: the December pilot text listed them, while a June 30 Maeil Business Newspaper Q&A says a same-carrier phone swap is excluded. I make no claim about upgrades, and I would ask the counter.
| Date | Step | Status |
|---|---|---|
| Dec 19-23, 2025 | MSIT notice sets ID coverage; pilot starts at the three carriers’ stores and budget carriers’ online channels | Done |
| Mar 20, 2026 | Pilot extended to Jun 30 (formal launch had been set for Mar 23) | Done |
| Jun 30, 2026 | Mandatory rollout announced, with a roadmap through November | Done |
| Jul 6, 2026 | Face match mandatory for new lines and carrier switches | In force |
| Aug 2026 | Review of a stronger multi-factor system | Planned; no result seen |
| Sep 2026 | Automatic check for forged resident-registration abstracts | Planned; no report seen |
| Oct 2026 | Enforcement-decree amendment to make the face check’s legal basis clearer | Planned |
| Nov 2026 | Subscription-restriction service (가입제한서비스, gaip jehan seobiseu; M-Safer) offered by default at contract signing | Planned |
The delay from March to July came from the industry: carriers and industry groups asked for at least three more months to prepare operating manuals and fallback methods.
The order of events is the part I notice. The mandate came first, and the roadmap schedules the decree amendment that further clarifies the face check’s legal basis for October.
How Does the Scan Work, and What Can Koreans Do Instead?
The system compares a live face with the photo on the ID. A customer gets at least one try and at most three before moving to another method (MSIT rollout announcement, Jun 30, 2026). The ministry says the biometric data used in the check is not stored or kept separately, and that only the result is retained (Dec 19 notice). For a systems person that is the right shape: the carrier learns yes or no, not a face template. I cannot audit it, and a notice is a promise, not an inspection report.
Nobody is forced in front of the camera. A customer who dislikes biometrics can use the Interior Ministry’s mobile ID app instead, and the Q&A says this works on both in-person and online channels. Someone without a smartphone can bring a resident registration abstract (주민등록초본, jumin deungnok chobon, a certificate of your registration record) issued the same day. Reports also say that if the match fails but identity is confirmed another way, activation can go ahead with the process recorded, under certain conditions.
If you live with Korean in-laws, they are the people who will be asked. The advice is dull: bring the physical ID, and install the mobile ID app beforehand if the scan makes them uneasy.
Whether the mobile Residence Card (모바일 외국인등록증, mobail oegugin deungnokjeung) can play the same role for a foreign resident is not something the notices say. My earlier post on a coworker’s hour-long fight to set up that card covers the carrier, phone-OS and NFC limits that stood in the way.
Why Were Foreign IDs Left Out?
The stated reason is a database problem. ID Tech reported on June 23, 2026 that MSIT said the work to link the scanning system with the separate foreign-identity databases is not ready. An MSIT official told Safety Times the same day that running the domestic system first and speeding up the follow-up development was the more appropriate policy call.
A second gap sits behind the first: the card itself. A face match says the person at the counter resembles a photo. It does not say the card is genuine, and if the reference is a forged card’s photo, a perfect match still passes. As I read it, that is why the ministry pairs the scan with an ID authenticity check (진위 확인, jinwi hwagin). For foreigners, the June 30 announcement says the Justice Ministry (법무부, beommubu) will upgrade that check in stages.
The dates do not line up. I had been reading “second half of 2026” as one firm date until I put the sources side by side. A Dec 24 MSIT briefing (korea.kr) repeated the Dec 19 notice’s second half of 2026 for foreign IDs and said the ARC photo authenticity link with the Justice Ministry had 2025 budget and was due in 2026. In July an MSIT official told Asia Business Daily that foreign registration cards and passports lack a fully developed authenticity verification system and the ministry was preparing to introduce one in the second half, with budget set aside. The outlier I found is the same June 30 Q&A, as Maeil Business Newspaper carried it on Daum News, which points later: a Justice Ministry-backed framework “around next year” (2027). My reading is that the ARC scan is aimed at late 2026 but leans on a piece that may land later, so I would not plan around a date.
Which Burner-Phone Percentage Is Which: 45.9% or 73.3%?
Burner phones (대포폰, daepopon, phone lines opened in someone else’s name) are the reason for the rule, and two foreign-name percentages travel with it. They measure different things.
| Figure | Base | Source |
|---|---|---|
| 45.9% (106,018 foreign-name vs 124,889 Korean-name; ID Tech rounds to 46%) | Phones seized 2020 to 2024, five years pooled | National Assembly data, via ID Tech (Jun 23, 2026) |
| 73.3% | Share of illegal phones detected in 2024 alone | Asia Business Daily (Jul 7, 2026) |
| 71,000+ | A count of foreign-name phones in 2024, up from 474 in 2019 (not a share) | Korea Herald (Oct 14, 2025) |
A pooled share is a weighted average of the yearly shares. If all three figures come from the same police series, which the reports do not say, a 73.3% year inside a 45.9% window means earlier years ran lower, and 2024 alone would be about two-thirds of the five-year foreign total (71,000 divided by 106,018 is 67%, my arithmetic).
Do the numbers say the rule works? Not yet. Police data put detections at 97,399 in 2024 (a National Assembly submission reported in Oct 2025). Seoul Economic Daily’s Sept 19, 2026 report then gave 20,303 for 2025, about 79% lower (my arithmetic) after ID-document checks were tightened, and 15,446 for January to July 2026, already 76% of last year’s total, with 4,292 at the three major carriers, about 83% of their 5,187 for all of 2025. One outlet supplies these figures, so I build nothing on them. Phones caught in that window were probably opened earlier, so it cannot show yet whether the face check helps.
What Should Foreign Residents Watch Before Year-End?
None of the June 30 roadmap’s four dated steps, August through November, targets foreign IDs in the reporting I read. The November item, the subscription-restriction service (msafer.or.kr), locks your own name against new lines, and today you must apply for it yourself. The foreigner-specific step, the Justice Ministry’s staged upgrade of ID authenticity checks, has no month attached.
Meanwhile the notices leave the counter routine for foreign customers where it was before July, and it varies by carrier. Korea Herald’s Oct 14, 2025 report is the last carrier-by-carrier look I found:
- SK Telecom: postpaid lines for foreigners generally only with an ARC (with separate rules for diplomats, US military and overseas Koreans).
- KT: a single passport copy for certain visa holders (E-7, E-9, D-2, D-4), and many outlets only scan passport images and check them by eye.
- LG U+: passports allowed, with extra documents (an employment contract for E-7 and E-9, an admission letter for D-2 and D-4) plus in-person verification.
That snapshot is about eleven months old and may be outdated. A June 2026 expat guide still says postpaid lines generally require an ARC and could not confirm whether passport-only registration had ended.
If I were a foreign resident opening a line this quarter, my plan would be unglamorous. Bring the ARC, ask the counter which extra documents that carrier wants, and ask outright whether they will run a face check on your card, because the answer tells you what that counter does today, which no notice can. Then search korea.kr for 외국인등록증 안면인증 once a month, since English coverage lags.
Dates and coverage are as of Sept 21, 2026 and can change without notice. This is a reader’s guide, not legal advice.
