Real-World Snapshot

Imagine a growing startup in Oxford. Before 2026, every employee number came with 662. But from January 30 onward, new hires might get numbers with 471. Still, all staff dial the complete ten-digit format whether it’s 662 or 471. No one needs to change existing business cards—but they should include the full number going forward, just in case.
