Recently, along with the emergence of cases of one-way service temporary suspension due to incomplete authentication, many users are concerned about the question: After June 15, when will the subscriber be two-way locked?
This is also one of the most easily confusing contents in the process of implementing subscriber authentication according to Circular 08/2026/TT-BKHCN.
Once locked in one direction, when will it be locked in two directions?
According to current regulations, two-way locking is not calculated from June 15 but is calculated from the time the subscriber is temporarily suspended from one-way service.
The handling roadmap for the blocked one-way subscriber group includes the following steps:
- The network operator sends a notification requesting information verification.
- If the user does not perform authentication as required, the subscriber will be temporarily suspended from one-way service.
- After 60 days from the time of being one-way locked but still not completing authentication, the subscriber may be two-way locked.
- After about 5 more days, the subscriber may have their contract terminated and their number recovered according to regulations.
For example, if a subscriber is locked in one direction on May 10, 2026, then the time of two-way locking may fall around July 9 or 10, 2026. If authentication is not continued, this subscriber may have their number revoked around July 14 or 15, 2026.
This means that the time of two-way locking for each subscriber may be different, depending on the date of previous one-way locking.
After June 15, are all unverified subscribers being double-checked?
According to the provisions of Circular 08/2026/TT-BKHCN, June 15, 2026 is the time to end the 60-day transition period from the date the circular takes effect.
This is not the milestone for all unverified subscribers to be double-locked or their numbers to be revoked. After June 15, telecommunications businesses will continue to implement the handling roadmap for subscribers who have not completed verification as prescribed.
For subscribers who have never been one-way locked, handling must still be carried out in the order of notification, authentication and temporary suspension of service according to regulations.
In other words, to determine the time a subscriber is locked in both directions, you must first know when that subscriber has been locked in one direction.
What should users pay attention to?
According to telecommunications businesses, users should proactively check phone numbers that are in their names on the VNeID application, and at the same time monitor notifications from network operators to promptly carry out verification if they are required to update information.
In recent times, many cases have only begun to pay attention to regulations when detecting that the subscriber's dial call is locked. However, if they continue to ignore authentication notifications, the subscriber may still be locked in both directions and the number may be recovered according to the handling roadmap.
