The 411 service became decentralized with the break up of the Bell System into regional Bell carriers. As such, the local Bell or AT&T service has real-time 411 information. However, it aggregates data from other carriers every three days. This is also complicated by the fact that other, non-Bell carriers are not required to share their customer lists with 411 and may not be listed at all.
