The Regulator Told Carriers to Make It Harder

The Federal Communications Commission adopted rules aimed at protecting consumers from SIM-swap and port-out fraud, placing obligations on wireless carriers to verify subscriber identity before transferring service or a number.

Placing the obligation on the carrier is correct, and it is worth setting out why, because the alternative allocations have all been tried.

The subscriber cannot prevent a swap they are not party to, per the interaction figures at 26-0120. The receiving carrier is being asked to accept a port request that looks routine. The downstream services that trust the number — banks, exchanges, email providers — have no visibility into the transfer at all.

The originating carrier is the only entity holding the subscriber relationship, the account history and the authority to refuse. Regulation placing the duty there is regulation placing it where the capability is.

Number portability was itself a consumer-protection measure, mandated so that switching provider would be easy and customers would not be locked in by their phone number.

Anti-fraud verification pushes directly against that. A carrier applying strict checks to outbound ports is, from another angle, obstructing a customer leaving — which is exactly what portability rules were written to prevent. Regulators are effectively tuning between two of their own objectives.

A carrier bears the cost of stronger verification — support time, friction, complaints — while the losses fall on the subscriber and on the downstream services. It is the externality this desk described for compromised customer equipment at 26-0529.

That is why the obligation has to be regulatory rather than commercial. It is also why compliance should be measured on outcomes rather than on documented procedure, and the useful figure — swaps per million subscribers, by carrier — is not published.
